Bought our house about six month's ago with a pool that had been kept for years with tablets in a float with the pump timed to run four hours a day.Pool store testing says i have too much stabilizer and should do a partial drain which I plan to do slowly as the summer rains progress.Sounds like my problem with maintaining chlorine is CYA.Have been maintaining chlorine levels with liquid chlorine without too much of a problem until we got a rainstorm which put three inches of water in the pool after which I would add from 1 pint to 1 quart of chlorine to the pool when pump started,about noon the lever would from 2-4 ppm but the next morning no chlorine.Two days ago I added two gallon 10% chlorine and ran the pump for 28 hours.PH was 8 so added 18 oz muratic acid which brought the ph to 7.5. with the chlorine off the 5 ppm poolmaster test kit.Test kit says my ph is 8+ put with my ph meter set with proper solution and tap water testing normal i bolieve it instead of the test kit.
I have had experience in managing water quallity in a cooling tower and thought the pool would be easy but finding it somewhat complicated.This site has been a big help in managing my pool.
