Levels today: FC 5.0 CC 0 PH 7.4 ALK 90 CYA 50 Temp 92. HOORAY!!! Clear water, levels good, NO brown dusty spots, not yellow dusty mustard algae. And we did it with out going to the pool store. Well, let me take that back. I did buy some stabilizer since ours was less than 30. Thanks to all who helped us get back in our pool. Could not have done it with out you. I can't believe more people don't do this. How much bleach would you think I will need per week when the pucks come out? How fast will the levels drop? Am I going to have to test everyday? Again, thanks to all who contributed to our nice clean algae free pool.
