Definitely switch to liquid chlorine, you can use LIQUID Pool Shock (which is 12% sodium hypochlorite) or Plain Household Bleach (which is 6% sodium hypochlorite)Thank you! I just did the CYA test and it's at 30 on the dot. As far as how to keep, CYA, PH, and chlorine in check what should I do? Continue with the PODS, or go to liquid chlorine. I think as of today my chlorine is high at 6.5 PPM
