The surrounding environment, warm summer days, and a high pool activity level are all factors that affect the pool water. 

The wind continuously adds microscopic debris to the pool water, and at times there will also be more debris falling from trees and pollen, which adds bacteria and impurities to the water. 

Warmer summer days will also provide better growth conditions for deposits in the pool, which requires additional water care products and extra water circulation. Large amounts of rain water can also affect the water pH value, making it acidic

This requires adjustment of the pH balance and extra water care products. Follow the water care steps for the best results. 

Enjoy the water!
