40,000 gal. inground pool, pH 7.4, FC 10, CC 0.5, TA 100, CYA 30. Tests done with Taylor K-2006.
We tried to turn our green swamp into a clear pool without emptying it. This might have been a bad idea. Now the pool is blue but not clear. We can't see the bottom of 5 ft. We also had a lot of white foam on the pool when we started this after backwashing. Now the foam has stopped. Do we have to let all the water out or just some, or is there anything else we can do to get it clear and sparkling? Please help!
