Pool went unused for 2 years. Full of leaves, algae, frogs, etc. I have managed to clean all that out. My chlorine, calcium, ph ,etc. are all near normal range. The problem is the pool, after running the filter for over 72 hours straight is still cloudy blue. When I put the vac pole in I can see about 2 feet down and that is it. When vacuuming on the filter setting dirty water was coming back in via the jets right away so I switched to backwashing to waste. When I do backwash, the sight glass never changes color. Doesn't ever seem particularly dirty. When I open the tank drain it smells real strong of algae, dirty water. (I assume this is normal) Filter pressure gauge needs replacing so can't say if that has changed any. The pool was either not cared for at all or very little for the past 5 years. I was planning to test by putting D.E. into skimmer but that is $20 for 25 lbs. so why not change sand at a cost of about $36? I know the thinking is sand rarely needs changing, and dirty sand works better but I also saw on here were it was suggested if pool is still cloudy blue/grey then it could be sand. If not sand, then is there a clarifier you would recommend? First time pool owner so very new to all the chemistry, etc... Thanks
