Hello Again....... I have a Jandy system now. Prior to that I had a Chlromatic. After 11 years I needed another cell Chlormatic was out of business, so I had to get a complete Jandy system. My original aaaand still being used equipment is an American Products Ultra Flow Pump & a 22 Inch Eclipse sand filter. Sand was changed when the new Jandy was installed. It looked as good as the new sand. None of my equipment has ever been rained on, or had sunlight hit it. It is all enclosed in a special room I designed for it when I built my home. I have always had a pool cleaner who tests the water weekly. The water reports I got was just to see that he was keeping my water balanced. I'm sure the PH has not always been in range, but from the looks of the pool, it's been pretty close for 14 years.
The Algea Dust is just that. You touch it underwater a disappears into the water till it settles again. I have seen posts about algae dust on the web before. Very hard to get it out of the system. My PH is hard to get below 7.9 and the alkalinity wants to keep dropping. When I do add acid, I walk it in small amounts. Any idea there?
I live in Destin.
