Kill Power: A Smarter Way to Measure Pool & Hot Tub Water Chemistry

Most pool and hot tub owners set a weekly schedule to measure and balance their water, requiring test strips, tables, interpretation, and calculation before chemical dosage. But the pHin team developed a smarter way to measure, they call it “Kill Power.”

Rather than measuring the specific levels or parts per million (PPM) of the sanitizer that is in the water, a Kill Power rating is an analysis that focuses on ORP (oxidation-reduction potential) that shows how effectively the sanitizer is doing its job, for chlorine, bromine and saltwater sanitizers.

Proper ORP levels are important for understanding the effectiveness of your chemicals. OPR sensors within the pool and hot tub water will have a voltage created between them from the electrons in the water, measuring the ORP reading. If the chemicals aren’t bonding properly, sanitizers become less effective. When ORP is low, the chlorine has a hard time keeping up with the bather load and additional adjustments are needed to get the pool balanced.

When ORP is high, the water’s cyanuric acid levels are also high which is the number one factor that can prevent sanitizer from working effectively. Factoring ORP levels in overall pool and hot tub water readings allows for a detailed analysis of the cleanliness of the water and its ability to break down contaminants.

How pHin measures “Kill Power”

pHin constantly measures the pH, sanitizer, and temperature of pool, hot tub, and swim spa water. Kill Power is measured electronically through the pHin monitor’s sensors, and is used as a factor when calculating chemical dosage recommendations that users see in the app.

When taking measurements, pHin analyzes the ORP level of the water to make sure the sanitizer is doing its job to keep your pool safe. pHin has built-in algorithms that analyze the water samples over time. With this data, pHin simplifies the chemical dosing process for pool and hot tub owners by providing easy to understand chemical instructions for balancing the water.

pHin factors your pool or hot tub’s Kill Power/ORP level into all measurements and makes it easy to read with a color-coded system, so you can always know whether your pool or hot tub is safe.

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.

Stuck at home? Stay Fit and Sane with your Pool or Hot Tub

Communities are encouraging everyone to stay at home amid coronavirus concerns. While families are staying in, their pool or hot tub can help maintain sanity and offer fitness benefits as well.

The CDC has advised that “There is no evidence that COVID-19 can be spread to humans through the use of pools and hot tubs.” If school, work, and the gym are closed, a pool or hot tub can help families stay fit and have fun as long as the water is properly cared for. Here are some ideas from the pHin team:

#1: Schedule Workouts

Don’t let the shutdown stop your workout routine – make your pool your home gym! Set a schedule for swimming; it’s a low-impact, full-body workout that improves muscle tone, cardiovascular health, and overall energy. You could also try water aerobics if laps aren’t your thing.

#2: Hot Tub Therapy

Whether you’re stressed or need some muscle relief from the tension of sitting at a home office all day, a hot tub can help. Astudy from Healthline showed that warm water can help reduce the hormones related to stress. When you’re soaking in a hot tub, leave your phone behind and focus on the warm water and massaging jets. Read more benefits of a hot tub here.

#3: Fun and Games

If you’re staying home with your family, keep them entertained with pool games. Country Living recommends inflatable Tic-Tac-Toe, Number Basketball, and pool noodle races. If you have a hot tub, try water cards, or water battleship. In water battleship, you’ll need two cups: Take turns pouring water into the empty cup. Take five-second intervals in between each player – the person who sinks the cup loses.

Stressed about keeping your water healthy? pHin is here to help. Don’t worry about balancing the right chemicals to keep your family safe. pHin floats in the water constantly and will tell you at a moment’s notice when you need to adjust your water balance.

How to Make Pool Time the First Step to #SelfCare

#Selfcare has been trending lately as we focus on improving our physical, emotional, and mental well-being. The self-care revolution is a positive force, but it can be challenging to make these changes in our day-to-day lives.

Pool, hot tub, and spa owners have a leg-up on setting a wellness routine with hydrotherapy, swimming, and time outdoors. The pHin team put together a few ways to get started:

1. Shut off the notifications and pick up a book

Alone time can be the start of self-care – and spending time by the pool or hot tub with a good book or relaxing music is a great way to escape the daily hustle. Set aside time each week to leave your phone behind and pick up a good read – especially if you don’t have a waterproof phone! Set a playlist for 30-minutes to an hour and leave your phone out of reach.

2. Connect with nature and enjoy the outdoors

An article from Mental Floss points out that spending time outside can improve memory, fight depression, and lower blood pressure. Breathing in fresh air and listening to the sounds of nature can help relieve stress and improve your focus. Head out to the pool for extra sun and some Vitamin D when winter is over – invite friends for a swim, hang out on a floatie, or enjoy the jets in your swim spa.

3. Hydrotherapy and exercise

Exercise is a major part of physical and mental well-being – Medline Plus notes that regular physical activity can improve your mood, increase your chances of living longer, and help control your weight. Pools and spas are a great place to exercise, providing resistance and buoyancy that is effective without being high-impact. Squats, shoulder rolls, water aerobics, and more can be the start to your physical fitness in the pool; a hot tub can also be a great place to unwind after a difficult workout.

4. Family wellness

A self-care routine can also be shared with the entire family. Spending time together in the pool relaxing, playing games, or working out can help you connect, have fun, and achieve better wellness together.

Tip: Use technology for peace-of-mind that your water is safe for self-care time

To maximize the benefits of self-care from your pool or hot tub, technology can help provide peace of mind that your water is always safe for swimming. With pHin, you can check the water temperature before you dive in using the app, and it’ll also tell you ahead of time if your water is out of balance or needs chemical adjustments. Knowing your water is balanced can help make whatever pool or hot tub routine you choose even simpler.

Smart Pool Technology Helps Early Adopter Manage His Pool Water

Technology is making our lives easier, whether it’s household supplies showing up at our doorstep on a schedule or smart home devices helping save energy and provide us with peace of mind. Many pool owners don’t know that smart connectivity can even make pool care easier too.

California homeowner Shannon Jean has been a technology early adopter for years and decided to extend tech to his backyard. He’s always relied on a local pool company to keep the water in his home pool balanced, but he sought another way to take control of his pool care. He heard about pHin, a smart water monitor that helps pool owners monitor and manage their own water care.

“I watched a few videos and testimonials about pHin before I bought it. One day I decided to ‘jump in,’” said Jean. “Because I’ve never taken care of the pool, my main concern was that I didn’t want to screw it up.”

pHin makes pool care easy – the monitor floats in the water 24/7, taking over 1,000 measurements per week. Users can see the status of their water’s pH, sanitizer, and temperature in the pHin App, which also sends them alerts when it needs attention. The system has built-in intelligence – it analyzes the water data to provide an easy-to-understand, color-coded water status. When users get an alert, they can see whether the water is safe for swimming or if it needs attention.

pHin makes water analysis easy to understand and doesn’t stop there – it also gives users exact instructions to balance the pool water for most chemical brands, for saltwater, chlorine, and bromine pools. “In the morning I go out to my pool, and it tells me what to do.”

“I’ve had pHin for about a year and a half, and it works fantastically, and I don’t know anything about pool chemicals,” added Jean.

Customers can choose any chemical brands to use with the pHin system. Jean follows the pHin app on his phone, which tells him exactly what to do for chemical dosage. “When I have had problems or questions, the pHin customer service has been great and they get back to me quickly,” said Jean. “Their customer service isn’t cut-and-paste – it’s a real person that troubleshoots with me.”

 “With the pHin app, the whole pHin system is pretty powerful.”

3 Steps to Stress-free Pool Care with pHin

 There are many perks to having a pool– relaxation and pool parties, or a nice après-ski soak. New pool owners might not realize the challenges of ongoing maintenance required to keep the water clean, healthy, and ready for a good time, so we’ve rounded up some essential pieces of pool maintenance advice to help you manage your water.

Pool-care professionals recommend measuring your water chemistry at least once a week. If neglected, getting your pool or hot tub water balanced again can be a frustrating task that costs both time and money.

 A smart water care system like pHin helps take care of this task while taking the stress out of managing your pool or hot tub, with three easy steps:

1. Constant Water Monitoring

Most people check their water levels once a week or just before they hop in the pool but water chemistry is easily affected by how much you use your pool or hot tub, how many people are using it, the weather (especially rain and heat), water temperature, sunlight, and several other factors. The lag between water checkups can create an unhealthy water situation. Since weather and water temperature are always changing, it’s best to test your pool water as often as possible to make sure you have an accurate picture of its overall water quality. Between raising a family, working, and other tasks, it’s difficult for most people to consistently test their pool water more than once per week, which is why a smart water monitor like pHin is the best alternative.

Once you drop pHin in the water, it automatically starts measuring pH, sanitizer, and temperature levels — over 1,000 times every week! The daily measurements are collected and analyzed with the monitor’s built-in intelligence to show you the status of your water health at any time, along with an easy-to-understand guide that will notify you whether your water is safe for swimming, needs chemicals to be balanced, or is unsafe.

2. Automatic Alerts

With smart technology in the pool, you’ll always know the status of your pool water. The pHin app gives you information about the water balance and temperature while sending you app alerts letting you know when you need to adjust your chemicals. Knowing the status of your water at any time can help you ensure that your pool or hot tub is always jump-in ready. It also helps you with easy steps to set unbalanced water right – continue to step three to read how!

3. Chemical Instructions

pHin is your personal pool and hot tub water expert. Instead of having to learn the charts, tables, and measurements for proper water chemistry yourself, pHin analyzes your water quality and provides easy instructions to get balanced water. It works with most major retail chemicals and uses its built-in analytics to give you precise dosing instructions for balanced water based on the chemical brand you use, your pool system, and your pool size.  All you have to do is follow the instructions and check in to see your water status on the app. Whether you’re a new pool owner or you’re looking to manage your existing hot tub or pool water, you can get the full benefits with smart monitoring from 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.

The Ultimate Pool Opening and Closing Checklist

Opening and closing a swimming pool can be a challenge — even for a veteran pool owner. It’s easy to forget tasks, so we recommend having a checklist of all your pool opening and closing must-dos to avoid finding yourself scrambling to get everything done.

To save time, use our pool care checklist:

How To Open Your Pool:

●             Remove the pool cover. First, clear off any debris that has accumulated on the cover using a broom or leaf blower. To keep it clean year-round, plan to use your hose, a pool brush, and some dish soap to scrub the cover every three to six months to increase the lifespan of your cover and ensure that it continues to protect your pool from debris.

●             Vacuum and clean your pool. If you have a very dirty pool, the best option is to use a manual pool vacuum, or there are adapters available for ShopVacs. For pools that are in good, clean condition, automatic pool cleaners are a great option. There are a few different types of automatic pool cleaners, suction side cleaners, pressure side vacuums, and robotic cleaners, each picking up different size debris. After it’s vacuumed, scrub the water line to remove any calcium build-up and stains.

●             Refresh and fill your water. There is a lot of debate about if — and how often — you should replace the water in your pool. We recommend checking your water level and chemical balance when you open the pool. If you properly manage your chemical levels and follow regular maintenance rules, you shouldn’t have to completely replace the water, just simply add water when levels get low. When you open your pool, check your pH and total alkalinity before and after you bring the pool back to its full water level. The chemical densities will change along with the water level so it’s important to make sure that you are monitoring levels in real time. An automated smart water monitoring system like pHin by Hayward makes it incredibly easy to get accurate measurements so you can tweak your chemicals while you refill your pool for the season.

●             Test and adjust chemical levels. Whether you use chlorine, bromine, or saltwater, you must test the pH and alkaline levels before swimming. You could take samples and test manually — but if you want to make it easy, a smart water monitor will do the work for you. A smart water monitor like pHin tests your chemical levels over 1,000 times per week and sends an alert to your phone when you need to make an adjustment. You’ll always know when you need to add chemicals, balance or shock your pool so it’s ready to enjoy the minute you are.

How To Close Your Pool

●             Lower the water level. Reduce the amount of water in your pool during the off-season to avoid problems with groundwater and freezing temperatures. The amount of water you drain will depend on winter temperatures where you live and the type of pool you have. If you live in a colder climate, you should drain the water 4 to 6 inches below the tile line in order to avoid the risk of damage from frozen water. If you’re in a milder climate, you just need to make sure the pool water temperature is below 65 degrees to avoid algae growth, but you probably don’t need to drain any water.

●             Test and adjust chemical levels. Before you close your pool for the winter, check and adjust all of your chemicals so you don’t end up with a complicated science experiment when you’re ready to start using your pool in the spring. Check your pH, water hardness and alkalinity and make sure they’re in the correct range.

●                   pH should be between 7.2 and 7.6

●                   Water hardness should be between 175 and 225

●                   Alkalinity should be between 80 and 125 ppm.

●             Check and clean filters. Making sure that your filters are clean and functional helps ensure that your pool is clean and safe. Filters help remove debris, dirt, calcium, and oils that can make your pool water cloudy and dirty, but they need to be cleaned regularly to function properly. Clean filters in the spring and the fall for safe water, and this will also help preserve the lifespan of your pool equipment, pumps, and filtration systems. There are different types of filters and the method for cleaning each is a little different but having clean filters will help ensure that your pool is clean and also helps the chemicals maintain proper balance.

Learning how to open and close a pool is a challenge for many pool owners, but smart pool owners use tools that make it easier. We hope that this checklist and the pHin Smart Monitor make opening and closing easier so you can enjoy your pool!

Rookie Pool Owner Solves the Water Care Equation with pHin

With pHin, a Texas family went from having green to crystal-clear pool water with less than half the work.

Experienced pool and hot tub owners know that it’s easy for water to get off balance. Whether from a heavy rainfall or a missed dose of shock, keeping a pool safe for swimming is an important chore. But new, inexperienced pool owners can mistakenly end up with green water if they’re relying only on complicated test strips and charts.

Aaron Richardson quickly learned the challenges of pool water care when he rented a Texas home with a 13,000 gallon pool. The owner provided basic pool care instructions: Throw two tablets in the skimmer and check the water quality weekly with color test strips. After following the original instructions to the letter, Aaron’s pool water quickly turned green. “I can read tables and do math, but the traditional pool care process is overcomplicated,” said Aaron.

Texas summers are hot. Not only was Aaron’s family unable to cool down with a swim, but he also had to scrub the pool each day in 103 degree heat. “We looked at getting a pool service, but it was expensive at about $1,200,” said Aaron. His family also needed a less  time-consuming alternative that would help them keep the water safe for swimming. Seeking a cost-effective solution, Aaron found the pHin Smart Monitor while searching online. The $350 device is Wi-Fi connected and designed to float in the pool — taking over 1,000 measurements a week. Paired with the subscription service, pHin measures sanitizer, temperature, and pH levels in the pool water, sending results and dosage instructions to the user on the pHin smartphone app.

“When we started with pHin, it told us everything we needed to do, including shocking,” commented Aaron. Instead of relying on traditional test strips and complicated charts, Aaron used the exact chemical doses from pHin. Once starting with the instructions, he was able to quickly balance the pool water. “After the first few dosing instructions, I went from scrubbing the pool every day to between ten days to two weeks.”

pHin helped make the difference whether it was pool chores or pool parties. At the end of the summer, Aaron’s family planned a Labor Day pool party for their family and friends. To prepare, a simple check on the pHin app showed that the water quality was “in the blue” — perfect for swimming. The pHin Smart Monitor also made it easy for Aaron to check the water balance after the party, simply adding the prescribed chemicals as needed. Instead of spending time with test strips and complicated charts, pHin makes dosage easy and manageable in Aaron’s day-to-day life, “I can even toss shock in while I’m walking out to my car,” he said.

 

Since using pHin for pool care, Aaron can relax and enjoy a swim after work instead of scrubbing the pool. “I’m a new pool user, and it couldn’t be easier to use pHin,” he said. “After pHin, I had a crystal clear pool with much less effort.”

The 9 Common Hot Tub Questions

Hot tubs are a great way to unwind in the privacy of your own home or backyard. Whether it be with family, friends, or even just by yourself after a long day, your hot tub helps melt away stress and lets you relax. Since you never know when opportunity will strike, you want your tub to be ready whenever the mood strikes. This can be difficult if you don’t know how to maintain your spa, but caring for your tub should be just as easy as relaxing in it. Here are the top hot tub questions to consider.

1) How Often Should I Clean My Filters?

You want to thoroughly rinse your filter with fresh water every other week. A garden hose works great for this, since it easily dislodges hair and most other materials from the filter. You should also soak your filter cartridge in a filter-cleaning compound every three to four months, as well as whenever you change your water. Keep two filters on hand – one in the spa and a clean, dry spare. This allows you to pop in the spare while soaking the main filter. Then, after you rinse the cleaning compound off after the original is done soaking, you can replace it and clean the spare. Your filters last longer and you get to keep enjoying your hot tub.

2) How Often Should I Drain My Hot Tub?

The answer mainly depends on how often you use the tub and your sanitizing system. However, draining and refilling your spa every three to four months is a good schedule to follow to ensure that contaminants and solids that dissolve in the water do not become excessive, which makes it difficult to maintain proper sanitation.

3) Why is My Water Cloudy?

Cloudy water in your spa usually means one of two things: either the filtration system is failing to clean smaller particles out of the water or bacteria are growing in your spa. If it is a problem with the filtration system, products that act like a coagulant to trap the dust and dirt should help. Just make sure to pull out and clean your filters once the hot tub is clean, otherwise the coagulants can break down and reintroduce all the dust and dirt they just collected. If it is bacteria you need to act fast and use a double dose of both chlorine and non-chlorine shock.

4) Can I Use Pool Chemicals in My Hot Tub?

It might seem like a good idea to just use pool chemicals for your hot tub, but that is a big mistake. Pool chemicals are much stronger than those meant for a spa and can cause serious damage to your tub. When it comes to buying the chemicals for your spa, remember that you get what you pay for. Cut-rate products are more likely to include fillers and additional chemicals that can cause issues with your water and the filtration systems. A quality product keeps your hot tub running well for years to come. In addition, product labeling differs between pool and hot tub chemicals, particularly as regards acceptable EPA guidelines. Chemical overdosing is very common when you use products specifically intended for a swimming pool in your hot tub.

5) Should I Use Bromine or Chlorine as a Sanitizer?

The chemicals that you use to sanitize your hot tub really come down to personal preference. Chlorine has a stronger odor, but is a very effective sanitizer. However, chlorine can also cause colors to fade, whereas bromine does not. Bromine also causes less eye, skin, and nose irritation and can be an effective sanitizer in its own right when administered properly in a two-part form.

6) Can I Get a Rash From My Hot Tub?

Yes, but it typically means that something is wrong with your chemical routine, not the tub. Skin rashes can be caused by both a surplus of chemicals and a lack of chemicals. For example, pseudomonas folliculitis is a skin rash commonly known as “hot tub rash.” It occurs when hot tub water is not properly sanitized. It is important to make sure the chemical balance of your water is exactly where it needs to be. This is where your pHin device comes in handy. But, when in doubt, drain, clean, and refill your spa.

7) How Should I Care for My Hot Tub Cover?

Twice a month you should remove the cover and wipe the entire surface with a cover cleaning agent. You only need a few squirts, and make sure to use a clean, damp cloth when you wipe it down. To guard against odors and bacteria growth, clean the underside of your cover with a mixture that is one part bleach to nine parts hot water. You may also use a cover cleaner such as 303 Aerospace vinyl cleaner and preserver. These products are available at most local pool and spa retailers.

8) Why is My Hot Tub Green?

Your hot tub should never be green; this means that there is bacteria growth in your spa. Drain the water and scrub every surface with a chlorine solution, then rinse the tub out with water. Refill your spa and shock the water with a dose of chlorine and non-chlorine shock. Remember, you should use your hot tub if the water is not crystal clear.

If the problem persists even after you sanitize the tub, your water may contain excess copper, which attacks the plumbing and equipment. Similarly, chromium may turn the water a lime green Jello  color. Proper water chemistry, especially pH, balances chromium and copper levels in your hot tub water.

9) Why Doesn’t My Hot Tub Get Hot?

The most common culprit when your hot tub goes cold is the filter. When the filter gets clogged, the heater shuts off because it needs water flow to be able to operate properly. Pop out your filter and give it a thorough rinse and soak in a cleaning solution. If your filters are over two years old, it is probably time to replace them. If cleaning the filter does not bring back the heat, turn the heater off for about 15 minutes. If it is still not working when you turn it back on, it is most likely time for a service call. Another common cause of heater failure is scale buildup on the heater core or element, typically caused by not using a stain and scale control. Scale buildup on the heater element of only 1/20” can reduce the heater’s efficiency by 40 percent!
