The Importance of Balanced Pool Water

Improperly balanced pool water can lead to algae resulting in a "green" pool

As a pool owner, having balanced pool water should be one of your top priorities. Water balance directly contributes to how your pool looks and feels, but more importantly, it affects the overall safety of your pool. With the right plan of action, you can ensure your pool stays balanced year-round.

What Happens When Your Pool Water Balance is Off?

You can usually tell when your pool’s water balance is off:

  • The water is cloudy or green.
  • The “chlorine smell” is strong (this usually means there’s too little chlorine in the pool — contrary to popular belief)
  • The water feels thick or slimy.

If your pool water is imbalanced, it may also be unsafe to swim in. Pools can contain a variety of microbiological organisms, including viruses and bacteria. When left untreated, some of these bacteria can cause health issues, like gastroenteritis and nose, ear and throat infections.

Maintaining balanced pool water is the best way to ensure your pool is healthy, clean and safe.

The Benefits of Balanced Pool Water

The health benefits of balanced pool water are paramount, but there are other advantages to maintaining water balance, too:

  • Prevents bacteria and algae growth
  • Ensures beautiful, clear pool water
  • Creates a comfortable swimming environment
  • Protects your pool from corrosion and equipment damage caused by too many pool chemicals
  • Minimizes health reactions from over-chlorination

How to Maintain Pool Water Balance

Getting balanced pool water is all about using the appropriate pool chemicals in the correct amounts with the right equipment. It requires keeping an eye on your filtration, chlorination, pH level, total alkalinity and calcium hardness.

If you’re hesitant about using too many pool chemicals, there are safe ways to reduce the amount of chemicals needed to maintain pool water balance. One solution is the Nature2® Mineral Sanitizer, a water sanitizing cartridge that uses EPA-registered natural mineral bed technology to destroy algae and bacteria with significantly fewer chemicals.

Aside from managing chemicals, the most cumbersome part of pool balance lies in checking the pool’s levels. You can easily monitor your pool’s balance with an automatic water balance reader, like the Blueriiot™ Smart Water Analyzer. It takes readings of your pool’s water balance levels in real time and notifies you via a simple smartphone app if something is out of whack. You can even have your pool pro alerted when a reading is off (available with the premium bundle).

Achieving Balanced Pool Water is Possible

Luckily, with the right technology and ongoing monitoring, maintaining balanced pool water is a pretty straightforward task. Be sure to talk to your pool professional for help setting up these technologies.
