New Pool? Tips for Getting Water Ready for Swimming

New Pool? Tips for Getting Water Ready for Swimming

You wanted a pool, longing to jump into cool water after a hot day, splashing with your family on the weekends, or floating around with a cocktail after work. So, you researched. You planned and consulted. You purchased, you landscaped, and you waited.

Congratulations on your new pool! A pool full of new water isn’t safe to swim in right away. To get the most out of it (and protect your investment), you need to prepare it before welcoming swimmers. pHin team put together what you need to know to get your water safe and ready for swimming:

Assemble your tools.

Every pool owner should have a standard set of tools they use to test and treat their pool water. That includes:

  • A water test kit
  • Pool brushes and cleaning tools
  • Chemicals
    • Chlorine or salt, depending on your system
    • Baking soda
    • Muriatic acid: One of the chemicals used to lower pH and total alkalinity in pools. Follow the instructions on the label, and make sure it is compatible with your pool; some muriatic acid can’t be used in hot tubs or with fiberglass, vinyl, or painted pools.
    • Sequestering agent: Iron and copper can build up in your pool. Sequestering agents help prevent staining and scaling by suspending the metal particles in solution.

Test the pool water.

Take your first water measurements with test strips to get the pH, chlorine, and total alkalinity levels of the water. You can purchase a test kit at your local pool store, or online.

Safe water should have pH between 6.8 and 7.2, and total alkalinity between 70 and 80 ppm.

There is a range for an optimal pH, which should then be raised between 8 7.1 and 7.7 for chlorine pools and 7.0 and 7.5 for salt pools. Lower pH provides better sanitizing benefits. At the same time, this will raise the total alkalinity. For example, concrete pools should have total alkalinity between 80 and 120 ppm, where painted, vinyl, or fiberglass pools should be between 125 and 170 ppm.

Remember, whenever you’re adding chemicals to your pool, use extra caution to prevent them from touching your skin or eyes, by using gloves or goggles. Keep the chemicals secured and stored safely away from children and pets.

Grab your scrub brush.

To get the water balance right, you’ll need to keep your pool clean.

As a best practice, brush the pool often using a nylon brush. Particles, leaves, or dirt can get stuck in corners, steps, and other crevices, so make sure they get extra attention. You can also use a pool skimmer to catch leaves or bugs that accumulate on the surface overnight.

After the pool is balanced, you may want to add algaecide. Always check with your manufacturer to make sure it’s compatible with your pool, how much to add, and when it would be safe to swim.

Let the water settle.

Your pool water needs time to run through the system. Allow the pump to run for 1-2 days, and, as you add chemicals through the process, you may need to wait a few days in between to allow for stabilization.

You should also wait until the chemicals settle before using a heater or vacuum. If you don’t wait, it could interfere with the pool’s curing time, which can cause long-term damage. Some experts recommend letting your pool cure for 21 days, but it’s best to check with your manufacturer or local pool expert to determine the most suitable time-frame.

Set your pool care routine.

Once your pool is open and ready for swimming, you need to set a routine to keep it safe. Schedule weekly water test strips and chemical adjustments.

If you’re brand new to pools, testing, and chemicals, technology like the pHin Smart Water Monitor can remove the guesswork of water care. Instead of testing just once a week, pHin gives you a clear picture of your water quality in real-time. The device takes over 1,000 measurements a week (few pool owners can match that by hand!), and sends alerts, reminders, and chemical dose instructions in the app. See what users think of pHin.
