I have a vinyl above ground 15,000 gallon with a Hayward pump and sand filter (150lb), which came with the house I recently purchased. The previous owners didn't put a winter cover on it, and it was green and murky. I hooked up all the plumbing, etc, scooped out as much gunk from the bottom with a rake as I could, got it going, and shocked the water. Took a test sample to the local pool store and got the water adjusted to the proper chemistry. After a couple days, the water turned blue but is now very cloudy. I ran the pump/filter 24/7 for a week, and it stayed cloudy. The pool store came out and changed the sand in my filter along with a bunch of gaskets and washers. 3 days later, after running the pump 24/7, it's still just as cloudy as before. There's chunks of white stuff in the water, I'm guessing is dead algae. What else can I do? My pressure gauge has stayed at 10psi and hasn't gone up. I tried adding clarifier but it made no difference. My chlorine levels are good and steady, the water has almost perfect chemistry, but I can only see maybe 3-4 inches into the water.
It seems all I have right now is $300+ of chemicals and repairs sunk into this pool, along with a very high electric bill from running the pump nonstop.
The pump and filter are located on the left side of the pool. There's a skimmer and drain pipe going into the pump, and the return pipe/jet coming out from the pump. At this point I have almost shut off the skimmer so the drain is taking most of the water, hoping that would clear more.
