Hello to all, ive been trying to get my chlorine to stabilize with no success yet. I have added 4 lbs of stabilzer, inn two pound intervals around 3 weeks ago and still my chlorine drops to zero reading with 36 hours. I bring the chlorine back up to acceptable ranges and within 36 hours its gone again. I have tested everything but the CYA levels, Ph is 7.2, Alkaline is around 120-130...not sure what the issue is. I know I need a test for my CYA but surely if it does not burn off, 4 lbs should have stabilized it..right?
