I have an in ground gunnite/concrete 32000 gallon pool in Maryland. Could not keep chlorine in. Treated for phosphates and confirmed they were gone. Had nitrate level of 15ppm. Pool store said that was causing the problem and I would have to drain and replace about 5-6 inches of water. The pool water people said I would have to drain 1/2 of the pool. Then I found your site and followed the instructions for "slamming" your pool with liquid chlorine. I only had a basic test kit, but put in 6 jugs of 8% Clorox bleach then more after that to where it has read well above the 5-10 ppm top of the test kit and have kept it there sine Friday (4 days now) But now I can't get the level to go down. I rained about 6" and am getting some fresh water this morning so that will dilute it some. Total chlorine has been reading in the 5-10 ppm on the top of the test kit. The chlorination has been off since yesterday. What should I do now?
