Wonder if you can please help with my pool problems, I am looking for a non liquid clorine method to maintain my parents pool, the home is empty and the pool is not used so I just want to keep it from turning green each week, I had to stop the pool guy as he was not arriving on time and each week would let it start to turn so right now I have a green pool previously used liquid clorine and tabs to maintain it. I don't mind storing dry chemicals but don't like the idea of liquids can anyone please suggest what I can use and how to start applying it with my current green pool?
A friend suggested TriClor? Is that an option maybe? I am located in central Florida if that makes any difference and my in ground pool is about 20k gallons.
