I had a fiberglass pool installed with a SWG and a cartridge filter. The pool company left it sitting for weeks with water in it before they hooked all of the equipment up. It looked like the scariest of swamps with crazy stuff growing on the surface. They got my water blue but never clear. It’s currently so cloudy that I can only see a few feet down but it is blue. The levels all tested in range on my Taylor kit and at the pool store. I tried a clarifier that didn’t really do much. I’ve been vacuuming, running the filter constantly, and scrubbing walls but nothing seems to help. I’m not sure what else to do.
