I have tried everything to clear up this pool. It was even new water because I had to drain it to fix the liner. It turned soupy green, i cleared it up, turned green again. I went to the pool store they gave me stuff that killed the algae but it was still cloudy white. I have even changed the sand in the filter because it was old. I've been able to keep it from going green again, even though every time i test it there is no chlorine in it, but i still cant see the bottom through the white cloudiness. I've tried clarifier but that makes it all sink to the bottom and when i try to get it up, it just clouds up the water again. I dont know what the problem is, i've had this pool for 6 years and never had a problem.
liner pool, i think its 12,000 gallons
hayward sand filter and chlorinator
use 3" tabs in the chlorinator and arm&hammer super washing soda for pH and alk
the shock i just bought claims to have clarifier in it but it doesnt seem to
