Chlorine Tablets

I am using Ultra bleach to chlorinate my pool. However, I still seem to have a problem keeping the level up on a daily basis. I get full sun on the pool. I have begun using some chlorine tablets to help keep the levels up. Is this OK? or am I not doing something right. My pool is approx 20000 gal. Gunite. I'm not sure what other information is needed to give appropriate advice. I love being able to save cost and keep a safe pool.

Hi,

I suspect your CYA is low. However, that is strictly a guess and can only be validated if you post test results for FC,CC, pH, Alk, and CYA. Those results will help us give you the correct advice to get you back holding more Cl than you are now.:)
