How To Use Chemicals To Treat Your Hawthorne Pool

One of the most difficult things to know when after getting a new swimming pool is how to use chemicals to balance the water chemistry. We all use chlorine for various purposed in our Hawthorne homes, so it’s a no-brainer that it is also a necessary pool sanitizer that makes swimming in our backyard pools safe.

Pool water chemistry isn’t something you are born knowing, so educating yourself about different chemicals is important if you own a swimming pool or hot tub in Hawthorne. Our Hawthorne pool supply company wants to educate you with the basics below on how to use chemicals to treat your pool.

Good Pool Water Chemistry

When you look at a pool testing kit, you’ll see that you aren’t just testing the pH level of the water chemistry. You’re also looking for chemicals such as total and free chlorine content, bromine, minerals, and phosphates. There are also test strips available to detect levels of bacteria and metals.

On the pH scale, 7 is neutral. For any pool in Hawthorne, target the level to between 7.2 and 7.6. A lower pH level indicates too much acid while a higher pH means too much alkalinity. Everything in the water will affect the pH level, so your pool chemistry needs to be balanced. You’ll often need to add certain chemicals to your pool.

Hydrochloric Acid

High alkalinity content makes your swimming pool water cloudy and will cause scale deposits along your pool tiles. It also irritates your eyes. Your pool equipment and plumbing system will also be affected. Muriatic acid is now known as hydrochloric acid and is used to lower alkalinity in swimming pools.

Chlorine tables that contain cyanuric acid will help to lower the alkalinity. It won’t be as effective at killing bacteria in water that has higher alkalinity content.

For a 15,000 gallon pool with a pH reading of 7.8 or higher, you’ll need to add about 1/4 of a gallon of hydrochloric acid. Be sure to test again afterward.

Sodium Bicarbonate

A low pH level means the pool water is too acidic. Adding sodium bicarbonate will raise the alkalinity. Make sure you check the balance about three days afterward so the entire body of water has time to adjust. Test and then adjust until the water chemistry is balanced.
