Really a great thing, I needed far more than any other care product to give (rarely a pH reducer). The water is crystal clear and the tabs are very economical (for 17500 liter pool reaches a Tab up to 2 weeks - the pump is also less). The water is soft and is also the chlorine smell hardly. I was a bit skeptical before but now convinced and will no other means more . Buy So simply can pool maintenance be - highly recommended!
