I have been trying to clear up my pool for almost 4 weeks. Had bad algae when uncovered and after 2 weeks got that cleared up; however, over the past 2 weeks, Leslie Pool continues to check water and make suggestions, which I try, but pool remains cloudy. I had my "last" visit with them 2 days ago and trying to test water and clear up on my own. The last reading from them showed 0 FC, 0 TAC, hardness ok, CYA at 0, TA at 60, PH ok - no metals. I was told to add alkalinity Up to raise alkalinity (used sodium bicarbonite). Increased the TA as well as PH - then added Power Powder Plus - 1 lb and approx hour later added stabilizer. This morning I tested for chlorine and still at 0, TA around 140 and PH around 7.4....BUT STILL NO CHLORINE AND POOL REMAINS CLOUDY. This morning - after testing - at 7 am added 2 more lbs of shock........and chlorine remains at 0. I am at my wits end and don't know what to try next. Help would be appreciated.
