5 Surprising Things That Can Ruin Your Pool Water Chemistry

5 Surprising Things That Can Ruin Your Pool Water Chemistry

Anne Booc |

Achieving and maintaining crystal-clear pool water goes beyond just adding chlorine and skimming off debris. You may be surprised to learn how some everyday nuisances can throw your pool's chemical balance out of whack without you even realising it. If left unchecked, these issues can lead to cloudy water, scaling, and skin or eye irritation. Let’s explore five unexpected culprits that can disrupt your pool water chemistry and how you can proactively manage them.

Sunscreen and Body Care Products

Many people don’t realise that sunscreen, moisturisers, and tanning oils can significantly disrupt the delicate balance of your pool chemistry. When these products wash off in the water, they leave behind residues that can cloud the pool and diminish chlorine effectiveness. Over time, these oils may accumulate, creating a scum line around the pool’s edge, making cleaning a hassle. To eliminate this issue, remind swimmers to rinse off before taking a dip.

Rainwater and Storm Runoff

While a refreshing rain might seem like a blessing, it can have detrimental effects on pool chemistry. Rainwater is naturally acidic, lowering the pH levels of your pool and diluting vital sanitisers. Moreover, storm runoff can introduce dirt, debris, and fertilisers, further complicating water balance. After heavy rainfall, always check your water parameters and adjust pH and chlorine levels as necessary.

Household Cleaners

Using standard household cleaners or soaps near your pool may appear innocuous, but these products can pose significant risks. Even slight traces can lead to foaming, chemical imbalances, and potential health hazards for swimmers. To maintain a pristine environment, choose cleaning products specifically formulated for use around pools to ensure safety and efficacy.

Overapplication of Pool Chemicals

It may seem counterintuitive, but even the chemicals designed to keep your pool clean can disrupt balance when overused. Excessive chlorine might cause skin and eye irritation, while too much algaecide or shock treatments can lead to pH and alkalinity issues. Always adhere to product guidelines, test your water following treatments, and remember that sometimes, less is more!


Swimmer Load and Daily Habits

The influence of swimmers on your pool water chemistry is often underestimated. Factors like sweat, hair products, deodorant, and even trace amounts of bodily fluids can affect water quality. More swimmers lead to faster chlorine depletion. If you're hosting a pool party, take the extra step to test your water both before and after and consider performing a shock treatment to restore chemical balance.

Keep Your Pool Water in Top Shape

Pool water chemistry can be more sensitive than most realise. From sunscreen residues to rainwater, these seemingly small things can add up quickly. The exciting news? Regular testing, careful maintenance, and choosing the right products can help you prevent minor issues from escalating into significant problems.
