Hello, this is my first post. I have recently opened my pool a few weeks ago. I noticed a lot of algae at the time. I did the normal pool opening routine, with all chemicals, and the water became cloudy, white/blueish cloudy. I have had the water tested, and it seems fine. The water looks nice, just not clear at all. You can only see about 2-4 inches from the top. I have purchased a new cartridge for my filter, thinking that was it, and still not different. I have had the filter running for days now, and nothing has changed. I have tried clarifiers, super shock treatment, and algae remover, and nothing yet. Please help!!
