I'm new to TFP and looking for some help. I am having problems keeping chlorine levels up in my pool. Ran tests today:
CYA well over 100
I have been adding shock and tablets almost daily and still having problems. My pool is about 9000gal in-ground, sand filter.
I am now draining 1/3 of my pool to get CYA down. Water is clear but burns eyes. I thank you in advance for your time and advice.
