We have a pool on the balcony. I wanted to avoid chlorine, but every 3 days it would turn green and clog the filter. With a heavy heart - I admit it :) - I bought the tablets and a floating dispenser. And the problem was solved. No more hassle and excessive water consumption (although I use it to water the garden). Finally, we can enjoy the pool. Of course, the dosage must be followed and it should be removed before use, as chlorine also has its negatives.

The tablets do not dissolve!!! I have had them in a bowl with water for 5 days and they remain intact, they smell very much like chlorine but they are hard and cannot dissolve!!!
