Kathy, I have been going through the exact same situation you have, AG pool, uncovered all winter, $$$ on chemicals and algecides, left with blue cloudy pool with no visibility. Nothing worked until I got my chlorine up to shock level. 72 hours later crystal clear pool! Since Saturday evening when I first started following all the information in this forum, I have put nothing but bleach in my pool to achieve these results.

Follow the advice of the experts on this forum, use the tools available ("best guess" chart and bleach calc program) and get that chlorine level up to shock level and keep it there, you'll see results!

P.S. First thing I did was get the 5 way drops kit at Wal-Mart to make sure my readings were as accurate as possible until I can get a really good kit. Worth every penny!
