pHin App Compact Mode Enables Remote Client Management

With pHin data at their fingertips, service technicians can efficiently initiate proactive water care schedules.

pHin has added Compact Mode to the pHin app, enabling service technicians to remotely view customer water data with an easy filter view and alerts.

A pHin Smart Water Monitor deployed in a client’s pool, hot tub, or swim spa measures the water pH, oxidation reduction potential, and temperature, with charts showing seven day, 60-day, and 90-day views. The measurements are taken over 1,000 times per week, and the proprietary algorithm analyzes the results to provide a color-coded status indicating whether the water is balanced, needs an action, or is unsafe.

Client management is streamlined with Compact Mode. Technicians can monitor a vast number of pHins through the app, streamlined with a filter view to search clients by location, vessel name, water status, and cellphone number. Technicians can also assign a custom name to the connected pHins, such as client name, address, location, or even a client’s separate units in a hot tub and pool. When the water is unbalanced and needs attention, they’re alerted in real-time in the app or via email so they can proactively schedule maintenance be

fore the customer even notices an issue. The data provided in Compact Mode can also be used to manage service schedules and delegating teams.

Compact Mode can be activated in the pHin app with a simple on/off in account settings with the most-recent version of the app. Technicians can add client pHin Smart Monitors to their account by scanning the QR code on the box or entering the serial number during setup to add the pHin to their account.

Why pHin Is The “Best Tech Investment” of One User’s Smart Home

Smart home technology can be found in more and more homes, offering convenience, peace of mind, and fun. Most devices are inside the home, like smart speakers, connected light bulbs, and smart door locks. But the smart home has now extended to the backyard with the pHin Smart Water Monitor.

John Clancy is a veteran pool owner, having managed pools in both of his homes over the last 20 years. An executive in the smart home technology space, his two residences are fully equipped with state-of-the-art Crestron smart home systems that he and his family use to control everything from the lights, shades, thermostats, TVs, and more. John is always testing the latest technology that can make his life easier, or even make it more fun. When John heard about pHin, it seemed like the perfect addition to his smart technology lifestyle.

After using it for a few weeks, pHin has already transformed John’s pool care routine. “I use pHin every day. I’ve owned pools for the last 20 years, and pHin makes enjoying and managing my pool convenient and easy,” he commented. Using the pHin smartphone app, his pool care routine is simple: John can see the status of his pool water any time in the pHin app, which has become a daily habit. Seeing important metrics about his pool at a glance, including the temperature, pH level, and sanitizer allow John to proactively manage the chemistry and temperature of the pool and maximize fun time. Instead of having to check chemicals and adjust the temperature on Saturday mornings, before a pool party, or in the afternoon for a workout, he can simply check the app and then jump in.

“I will also say that the accuracy at which the levels are reported from pHin are amazing,” added John.  “When my pool company was here this week for our weekly maintenance, their readings matched all three metrics exactly on my pHin app.”

pHin also accounts for the other elements of routine pool water care, providing test-strips and a reference card. It’s a simple process, analyzing a photo of the used test-strip in the app to provide other readings important to the overall pool chemistry. According to John, “The best part, which is unlike any other test strips I have ever used, is that it tells you exactly what chemicals and the quantities to add to remedy any unbalance.”

Whether you’re new to pool care or an experienced pool owner like John, smart technology like pHin can make water care simple.

Why and How Do We Shock Our Pools?

Seasoned pool owners know shocking is important to water care. When new pool owners research maintenance tips, they quickly find the advice: “Shock your pool. Shock your pool. Shock your pool.”

But, why do we shock?  

Regular pool shocks are critical to keeping the water safe, and to maintaining balanced water.

The main reason you need to shock is to get rid of the chloramines in the pool, which can be responsible for eye irritation and an ammonia smell. Shocking is an extra boost to burn off of bacteria so that the free chlorine can do its job.

Chlorine or bromine sanitizers can get overworked and need to be removed from the pool. This could be after a heavy rainstorm, lots of kids in the pool, or a pool party. Using a non-chlorine shock is the first step to eliminating bacteria, and doesn’t disrupt your chlorine or bromine levels, so your water can remain balanced.

How do you shock?

  • Check the label: If you have shock for a chlorine pool, carefully read the instructions to know how long the manufacturer recommends waiting before you can swim.
  • Set a schedule: Shocking your pool should be done each week – and it can be as simple as tossing a pod in the water. There are many brands that offer shock, so find what works best for your pool, or consult a local pool retailer or service technician.
  • Pick a time: Shock your pool when it’s not going to be occupied. These chemicals aren’t stabilized, so you may have to stay out of the water for at least a few hours to let the shock spread and start working, depending on the type of shock you’re using. Evenings or late afternoons work, or if you’re not a morning swimmer, maybe your shock can be in the morning.

In addition to pool shocking, make sure you check your pool water balance regularly. The right water balance keeps your pool safe to jump in anytime, and it can be simple. Pool experts created the pHin Smart Monitor, a system that measures your pool water chemistry, sends you alerts, and helps with chemical dosing.

6 Tips for Conserving Pool Water

On World Water Day, think ahead for summer savings.

World Water Day is on March 22 each year, right on the brink of the swimming season! Each year, it offers time to think about conserving water. Pool owners can take steps to conserve water to help the environment while at the same time, benefiting from saving money on water and electric bills.

The pHin experts share tips for saving water this pool season:

1.       Cover Your Pool

Most pool owners cover their pools during the off season, but a pool cover can be handy for conserving water during peak pool season. Covering your pool when it’s not in use will prevent evaporation that decreases water levels and requires more frequent pool refills. It will also conserve pool heat, reduce algae growth, and keep debris out of the pool.

2.       Check for Leaks

Regular leak checks on your pool will help you find issues that could cause water levels to get too low. When looking for leaks, keep an eye out for damp spots around the pool, cracks in the pool’s concrete, leaking pipes or valves, and saturated grass or soil. Staying on top of leak checks helps you stay aware of your pool status while stopping water drainage before it gets out of hand.  

3.       Heat Your Pool? Lower the Temperature

While it’s nice to dive into a heated pool (especially early in the season or in the fall), high water temperature can make pool water evaporate at a faster rate. If you use a pool heater, consider lowering the temperature when you’re not planning to use the pool or when outdoor temperatures are expected to rise — just turn it back up when you’re ready to jump in. Using the heater less will also reduce your overall electric bill!

4.       Block the Wind

A fence and pool-side landscaping are important for safety and privacy and can enhance the ambiance of your backyard. These features can also help reduce the risk of water loss — Fences and landscaping elements act as a barrier between the wind and the pool to keep water from evaporating.

5.       Only Drain When Necessary

Cleaning your pool regularly and maintaining proper water levels during the off season will reduce the amount of times you need to drain the pool. Your pool should only get fully drained once every few years. Rather than starting from scratch with an empty pool at the start of each season, regularly maintain your pool and the area. To drain your pool as little as possible, make sure you don’t overfill your pool. By keeping the water levels consistent, you won’t have to worry about water draining from splashing.

6.       Keep Your Water Balanced

Keeping your water healthy can also conserve your water. Proper maintenance yields less equipment damage and fewer pool repairs. Use a smart monitor like pHin to keep your water balance on track. It can help you with your pool conservation goals by alerting you the second your water needs attention or temperatures get too high and provides chemical dosing instructions.

3 Ways Smart Technology Makes Water Balance Easy

A pool or hot tub can be an oasis – if the water is clear and safe. A perfect morning can start with a freshly brewed cup of coffee, enjoyed poolside in the sunshine. Summer evenings are best spent with friends and a cocktail, supported by pool noodles or fun floaties, even with a cupholder. An afternoon swim can reduce tension, or a nightly soak in the hot tub can melt a stressful day away.

But if the water balance is off, hot tubs and pools can quickly become dangerous for swimming and relaxing.

Most pool and hot tub owners aren’t water experts. Balancing pH, sanitizer, and managing chemical doses often requires professional expertise to ensure safe water. But new intelligence and algorithms are making the water balance equation simple for any family, for peace of mind, alerts, and helpful tips whether they manage their own water or rely on a professional.

The pHin Smart Monitor floats in the water, and automatically measures the pH, sanitizer, and temperature up to 1,000 times per week. The device is made smart with built-in analytics, that it simplifies to make water balance understandable and more manageable.

Here are 3 ways pHin transforms your pool and hot tub water care routine:

1.            Real-Time Alerts: Since pHin monitors your water 24/7, you can expect to receive an alert about your water balance the second it needs attention on the smartphone app or via email. You can also use the app to check in on your water temperature before you jump in.

2.            Color-Coded Guide: Tables and charts can be hard to understand. pHin simplifies water balance with a color-coded system: Blue for safe water, Orange means you need to check the water, and Red means the water isn’t safe.

3.            A Chemist in Your Pocket: Instead of having to calculate how much chemicals you need to add, pHin syncs up with the size of your pool or hot tub and the chemical brand you prefer, and gives you simple, easy dosing instructions.

pHin provides simplicity and peace-of-mind for pool care. Whether you manage your own water or work with a professional, the alerts keep you informed about your water balance, so you always know when it’s safe for swimming, relaxing, and fun. And, if you have a pool technician – they can use pHin too to check on your water from anywhere – the information helps them prepare and intervene sooner when the water needs attention.

pHin is compatible with chlorine, saltwater, and bromine water systems.

6 Hot Tub Mistakes to Avoid

Hot tubs can have many benefits – they can help with a post-workout recovery, de-stressing, and even be a place to host parties. If not properly cared for and safe for soaking, hot tub water can pose health risks, like coughs and rashes. Yikes!

The warm water in a hot tub needs special care to remain a safe place for whatever benefits you seek, whether it’s fun, relaxation, or recovery. The certified pHin pool care experts put together a list of 6 Don’ts of hot tub care:

1.       Don’t cut the power on a full tub

Whether you use your hot tub regularly, a few times a month, or a few times a week, it’s necessary to maintain the same water level and a steady temperature. For both cold and warm seasons, this is ideal to maintain the chemical balance vs.  letting your hot tub cool down and then reheating it for each use.

2.       If you see green, don’t get in

If you’re ready for a soak and your hot tub water looks a little off, has a weird foam, green tinge, or flowing foam – don’t get in. These are signs that your hot tub water is unbalanced, unsanitary, or unsafe, and can have health risks. It will need chemical attention to be re-balanced, or you may have to drain and refill the tub to resolve the issue.

3.       Say “no” to plastic covers

Maintaining hot tub water is a delicate balance. A greenhouse setup or a plastic cover can magnify sun rays and trap heat in the tub. This extra heat can make it challenging to maintain a healthy water balance, and can even melt the plastic cover. It’s best to use the hot tub cover recommended by the manufacturer.

4.       Some like it hot – but don’t go over 104° F

The heat of the hot tub can be soothing for tired muscles, or even help with common headache symptoms. But be careful – a hot tub’s max temperature should be 104° F. Heating your hot tub above this level can be unhealthy and dangerous for swimmers, and could also damage your hot tub.

5.       Skip the soaps and suds

Aromatherapy can enhance hot tub relaxation, but it’s best to keep soaps, scents, and suds out of the water. Adding these products is not recommended by most hot tub manufacturers, as they can be detrimental to your system, requiring a drain and refill or  an expensive repair. It’s also a best practice to rinse off in the shower before getting into the hot tub. If you’d like some extra soothing scents, you can try an essential oil diffuser or candles in your hot tub space.

6.       Don’t forget your filters

For best results, hot tub filters need to be cleaned every two to three months and completely replaced every two years. Even if you don’t regularly use the hot tub, changing filters is important, because buildup can be a cause of unbalanced water and affect the lifespan of your hot tub. For a more efficient hot tub, the silver ion cartridge needs to be changed every four months.

Bonus tip #7: Use technology to monitor your hot tub water

Whether you have a service tech who manages your hot tub or you’re taking on the task yourself, the best way to know exactly what’s going on in your hot tub water is to have a smart monitor that analyzes it for you. The pHin has built-in analytics, a mobile app, and Bluetooth connectivity that keeps you informed about your hot tub water and guides you with chemical instructions.

Learn about the three simple steps for pool care with pHin.

pHin Reaches New Milestone: Over One Billion Water Samples Tested!

There are more than 15 million pools and hot tubs in the U.S., and even though water chemistry can be challenging, about 75% of owners test their own water. Maintaining healthy pH, sanitizer, and temperature levels requires water testing at least two to three times a week, which adds up to a lot of hands-on maintenance for pool and spa owners who’d rather be relaxing or splashing around.

pHin, was designed to streamline pool water care so families can just enjoy their pools without all the guesswork. Now part of the Hayward family, pHin has just reached an exciting new milestone: We’ve tested and analyzed over one billion samples of pool and hot tub water!

Because there are so many environmental factors that affect water chemistry such as usage, weather, water temperature, sunlight exposure and more, pool water can easily become unbalanced. pHin helps keep things in check by keeping a constant eye on the chemical levels. There are pHin monitors floating in  pools, hot tubs, and spas around the country, which have collectively taken over one billion samples!

When pHin takes a reading of the sanitizer, pH, or temperature that needs attention, it sends an alert to the user on the mobile app with instructions, so they know exactly what to do to keep the pool or spa water safe and ready for swimming. With a proven track record and years taking measurements pHin is family-tested and industry approved.

pHin is constantly improving to make pool care easier. Having taken over a billion water samples, the monitors provide families with exact instructions to balance their pool water with the chemicals of their choice from a growing database.

How to Clean Up Your Pool or Hot Tub After Hurricane Season

Weather-related disasters can damage pool and hot tubs with heavy wind and rain. As hurricane season comes to a close along the coast, here are some steps you can take to get your backyard back to a beautiful and safe oasis:

1. Clean up debris and check water levels

Start restoring your pool to its pre-season glory by cleaning debris from the pool water. If your pool doesn’t drain excess water on its own, remove the necessary amount of water to get your pool back to its normal water level. Check that the pump and skimmer aren’t clogged with debris to ensure they’ll work properly. A pool vacuum may be helpful for catching any debris or dirt that has fallen to the bottom of the pool.

2. Restore power to your pool

Flood waters caused by hurricanes may have damaged your pool or hot tub’s electrical equipment. Before restoring power, double check that no equipment is water damaged. If you are unsure, it’s safer to have an electrician double check the area. Once the power is restored, the pool will begin to filter properly again, getting rid of the small debris and particles that were not picked up during the cleaning process.

3. Check water quality

Hurricane flooding and rainfall could have contaminated your pool or spa area, making it unsafe for swimming. Before you re-balance the water, don’t let anybody (including pets!) swim until it’s back to normal chemistry levels. Pools should be at a 7 pH level, which can be affected by the hurricane; it’s also important to check the chlorine, hardness, and cyanuric acid levels in the water. Once you’ve gotten your pool or hot tub back in balance, use the pHin Smart Monitor to easily maintain your water health. pHin monitors your pH, and sanitizer and temperature levels over 1,000 times per week and notifies you when your chemicals need adjusting.

Considering a Hot Tub for the Winter? How to Pick the Right Hot Tub for You

One of the great things about the Internet is the amount of information at your fingertips at any given time. When you’re looking to make a major purchase, such as buying a hot tub, this wealth of information is a great help. Even if you’re replacing an old tub, chances are you bought the previous one some time ago and your preferences, as well as styles and features, may have changed.

Unfortunately, picking your way through the information online is often challenging. Before you start your quest, answer these questions. Then, let those responses guide your choice.

How will You Use the Hot Tub?

The main function of your hot tub should be the primary focus when purchasing. Are you looking to exercise with your tub? Perhaps you should consider one with built-in fitness equipment or a swim spa. If your goal is hydrotherapy, then you need to make sure the tub you choose has the proper jets and features designed for your particular health condition. You also need to consider how often it will be used. Will it be used daily? How long will it sit with nobody using it? In that case, you need to consider the amount of energy it will take. Your tub’s purpose comes first and foremost when deciding which model is right for you.

Where Will You Install It?

Location might not seem like that big a deal, but in reality, it is incredibly important. Will it be indoors? Then you need to place it in an area both large enough for the tub and that allows easy access for service calls. If you want it outside, you need a tub that stands up well against the elements and your particular climate. You also need to ensure there’s enough space for servicing the hot tub.

No matter where you put it, you need to make sure that the surface the tub rests on is level and flat, and close to both a power and water source. You’ll need the correct wiring to run the hot tub, so keep that in consideration when it comes to placement. As for water, you will need to empty and refill the hot tub a few times a year, so make sure that wherever you put it has adequate drainage.

Is the Tub Energy Efficient?

A hot tub requires electricity to run, so keep the energy efficiency of your tub in mind. The best hot tubs have high-quality insulation, and even indoor spas should be well insulated. It is also recommended that you get a thick, insulated cover so that your tub can retain heat even when it is not in use. Also keep an eye out for spas that use a separate pump system for the jets and water circulation, as they tend to be more energy efficient.

Residents of California should make sure that their hot tub meets California Energy Commission requirements.

What Size Do You Need?

Size might not seem like an important factor in choosing your hot tub, until you’ve taken it home to install in a specific space and it doesn’t fit or you can’t get it through the doors. Or, you go to set it up in your backyard and realize there’s nowhere to put it where it can be easily serviced. Portable spas are relatively small in size and can still accommodate two to three bathers without overcrowding. There are also above-ground and in-ground spas.

In-ground hot tubs typically don’t come in a large variety of sizes and are more labor intensive to install. Above-ground spas provide a larger number of size options and, while more labor intensive than an inflatable unit, tend to offer less maintenance requirements than an in-ground model. They also tend to be more energy efficient.

What Is Your Budget?

Other than the primary function of your hot tub, cost will probably be the biggest factor in choosing your new unit. Beyond the initial purchase price, you need to consider the cost of maintenance. Look at the accessories (steps, covers, etc.) and chemicals you’ll need to keep the tub in tip-top shape. Also consider long-term costs of running the hot tub. While the unit with solid foam insulation and a high-end filter might cost more than the one with basic insulation and filtration, it could save you money in the long run. Better insulation means retaining heat and spending less on power to keep the unit hot, and a better filter means less time and money spent on chemicals and cleaning. In some cases, spending more up front can save you more over time.

Additional Considerations

Research is key; look at models and specifications online, then go into a store to actually check them out. Most reputable dealers should let you test a few models to see how they feel. Consider everyone that may use the hot tub, including kids, friends, and family, and how the tub would be for them. When the time comes to actually buy a unit, you can purchase either in store or online, but make sure to ask about warranty service. It is also a good idea to buy from a dealer that has been in business for a while, since they are more likely to be there a year or two down the road.

The Importance of Collecting a Water Sample to Test

It will almost always be easier to avoid water chemistry issue than it will be to solve it. Eliminating something like an algae bloom once it already colors the water is no simple task. Once the walls are stained and the equipment corroded, the damage is done. Even worse is treating contamination. By the time swimmers or soakers complain about infections and rashes from contaminated pool or hot tub water, it is too late to prevent the spreading of disease. But, using proper sampling techniques and monitoring the chemical content of the water frequently helps you avoid costly, time consuming problems. It is incredibly important for pool operators to be familiar with good water testing kits and techniques.

Use a Sample Container

When conducting a test poolside, many people will just fill the four-in-one test bottles directly. This is perfectly fine provided you thoroughly rinse the bottle prior to collecting samples in order to eliminate any contamination and the pool’s circulation pump is running. Repeat the rinsing process between pH, alkalinity, and chlorine tests.

If you use a pool supply store to test your sample, most typically require eight ounces of water for testing. Some pool stores offer a free sample bottle. If yours doesn’t, make sure that you use a container that both meets the volume requirements and is free of contaminants. Thoroughly clean any repurposed container. Never use an empty chemical bottle, since it may throw off your sample, or pickle jars, since the salt and vinegar will never fully wash out. Also avoid coffee and juice containers as they can affect the pH reading.

Where to Gather Your Sample

Just as important as what you put your water sample in is where you get the water sample from. You don’t want to skim along the top, as that water is not an accurate representation of the entire pool. The recommended level to take your sample is 12 to 18 inches below the surface of the water, or about elbow-deep. Avoid the skimmer, return areas, and anywhere near a floating chlorine feeder to keep from getting an inaccurate chlorine reading. And, if your pool has varying depths, take the water sample from the deep end, which is less affected by temperature.

When to Take Your Sample

Something that many people don’t consider when taking a water sample is timing. Do not take a water sample if you’ve added any chemicals to the pool within the last 12-48 hours. While that may seem like a fairly large time-frame, there are a multitude of factors that may cause a discrepancy, such as the size of the pool and what chemicals you added. Most pool professionals should be able to tell you when to retest your pool’s water based on its specific circumstances. Rain also makes a difference. If it is currently raining, about to rain, or has just finished raining, do not take a water sample. After a rainstorm, wait at least eight hours to take a water sample.

Testing Your Sample

If your tests require using tablet reagents, do not touch the tablets when removing them from their foil packets. If they get wet or the foil packet tears, discard them. When using dip and read test strips, replace the bottle immediately after use; the strips can become reactive with moisture in the air. Pay attention to timing, as colors can change if you wait longer than the specified time. Follow the manufacturer’s directions carefully, since many involve more than one step.

Your samples should be fresh; taking a sample in the morning and coming back to it after going to work or running errands is not ideal. And, if you take a sample and it rains soon after, then that sample is no longer an accurate reflection of the pool.

Ensure that your testing instruments are properly calibrated and do not expose them to high humidity conditions, drop them on the pool decking, or submerge them unless they are fully sealed. It is a good idea to purchase wide range test kits since dilution testing can be a complicated and precise process.

Working with a Pool Store

If this whole process is new to you, be sure to provide basic information to your pool store, such as pool size (in gallons), pool type (fiberglass, concrete, etc.), sanitizer (chlorine, salt system), and anything that has been done to the pool in the last 48 hours.

Chemicals Demystified: Balance Pool and Hot Tub Water Chemistry in 7 Steps

Besides good filtration equipment and a general cleaning routine, chemicals are the most important factors to maintain a safe and healthy swimming pool or hot tub.

Your Pool or Hot Tub is Similar to a Mini Water Treatment Plant in Your Backyard

Just like how the municipal water you use at home for drinking, bathing and cleaning needs to be treated with chemicals at a water treatment facility in your area, the same way the water in your pool or hot tub needs to be treated. 

Unlike our lakes and rivers, which take care of themselves both ecologically and naturally, our pools and hot tubs are “self-contained” vessels and do not constantly exchange the water. Bacteria and aggressive water can deteriorate the surface of the pool or hot tub, damage the plumbing and equipment, and cause harm to bathers.

Chemicals Help Protect Your Investment and Keep Your Pool Sanitized

Almost every chemical used in a pool or hot tub is to protect the vessel and support system. Only the sanitizer and control of pH are tied primarily to bather health and safety. 

Minerals, pH buffers and shocks are required at times to adjust the water chemistry so that you, your family and friends can be safe from waterborne pathogens, algae infestation, perpetuated cloudy water and deterioration of the pool and its support systems.


7 Steps to Maintain Balanced Water Chemistry

Let’s start with the basics: Every pool needs chemicals. Yes, even salt water pools. The role of the salt water chlorine generator (SWCG) is to produce the sanitizer (chlorine or bromine) in the vessel. The SWCG does not maintain the pool or hot tub water balance and does not eliminate the need to add chemicals to maintain a worry-free pool or hot tub.

1. Go for products with high active ingredients

  • Make sure you get the most for your money: read the labels. Get the most concentrated active ingredients and low inert ingredients. It is typical to have some “inert” ingredients, however, the higher the inert ingredients, the lower the concentration of the active products. Whenever in doubt, ask a pool professional for a brand recommendation.

2. Know the parameters of your pool or hot tub

  • Be sure to know the water volume as accurately as possible. It will help you calculate the proper amount of chemicals to add without over- or under-dosing. Just like how you wouldn’t want to give an infant an adult-sized medication or vice versa, you wouldn’t want to over-or under-chemicalize your pool.

3. Add the right amount, evenly distributed

  • Always measure how much your are adding and follow the “directions for use” located on the product labels.
  • Unless stated otherwise, apply the required chemicals in the deepest part of the vessel and with the pump system operating to get a thorough mixture throughout the entire body of water. Rinse empty containers with the pool water and dispose or recycle as required.
  • Some interior surfaces and certain chemicals require pre-dissolving prior to adding them. Again, refer to the “directions for use”. Brushing behind newly added chemicals will help any undissolved product get into the solution and avoid staining or harming the pool or hot tub surface.

4. Follow the proper sequence

  • Since many chemicals interact with each other, make sure you add the chemicals in the proper sequence and avoid unnecessarily wasting the product. 
  • For instance, if the pH, total alkalinity and chlorine all require an adjustment, the proper sequencing to adjust those factors would go in this order: total alkalinity, then pH and lastly chlorine as each of those particular factors are dependent on each other.
  • Additionally, when the “directions for use” instructions call for a time delay, it generally implies a minimum period of time and not sooner than. 

5. Think safety first when handling chemicals

  • Always add chemical downwind and away from you to avoid coming in direct contact with the product.
  • Unless directed, do not add any pool chemicals into the surface skimmer to avoid damage or harm to you and the pool.
  • If there is a spill near the pool, rinse the spilled chemical into the pool water. If an acid is spilled away from the pool, neutralize the acid with some baking soda or copious amounts of water rinsing it to a fully diluted neutralized state. Avoid any spilled chemicals from coming into contact with your skin, eyes or clothing. Use gloves if needed.

6. Remove the cover

  • If you use a cover, always remove it when you add chemicals, and replace it when directed by a professional or the product label.

 7. Store chemicals responsibly

  • You know the drill: always keep pool and hot tub chemicals in a cool and dry area and away from children and animals. A plastic shed or storage bin works great as some chemicals may react with metal and cause staining or corrosion. Clearly label the products in their storage containers and do not mix products together as some can cause chemical reactions and health hazards.

Maintaining the right water chemistry can be intimidating and time consuming.
