Pool Chemical Maintenance

Keeping correct pH and chlorine levels is essential to making sure that pool water is kind to both equipment and swimmers. Fluctuating pH is one problem: Levels lower than 7.2 (too acidic) might liquefy plaster or concrete surfaces and trigger metal in the mechanicals to corrode. Greater levels minimize chlorine’s ability to eliminate bacteria, such as E. coli or those that cause ear infections and rashes.

Chlorine monitoring is similarly essential. “If you don’t enjoy the levels, you risk exposure to hazardous germs,” states Dr. Thomas M. Lachocki of the National Spa & Pool Institute (NSPI). At the exact same time that chlorine damages algae and bacteria, it bonds with nitrogen-based ammonia– mostly from urine, fertilizer, and the environment– forming irritating chloramines. It’s chloramines– not extreme chlorine– that sting the eyes and aggravate the skin. Paradoxically, adding more chlorine ruins the chloramines. Excessive chlorine– the NSPI’s requirement is a maximum of 10 ppm– can not only aggravate mucous membranes however rust system parts and fade your swimsuit.

Still, chlorine remains the industrywide favorite: As long as you’re alert, inspecting levels as soon as a week and more often during peak use, it’s a really reliable and safe sanitizer. The only thing better might be to boil the water.
