22,000 gal. Above ground intex pool. It's my first year and the water was crystal clear for a while and we were just testing and maintaining the chlorine and ph levels and all was good. Shock once a week and water was great then one day it turned cloudy and we have been fighting it ever since! Going in 3 weeks now fighting and taking samples to the pool store only to spend money on products they say will work but end up days later with the same results. Now I'm starting to get a slightly green tint to the water. Here are my levels today please help if you can. Thanks!!
Currently using a 6 way test strip so here goes...TH: 400, FC:2/4, PH:7.5, TA:180, CYA: 30-50. Again any advice you can give would be great we have never had a pool this large before. Thanks again!
