High cya battles led to me reading on this site which led me to believe going to pool store was a terrible idea. Long story short, I had what I felt no choice to go buy from there yesterday because my calcium hardness is way low considering how much water I’ve had to drain and refill with the high cya. While I was in there I told the guy he won’t see me much anymore because I’m converting to liquid chlorine after all my cya Trouble. He went on to tell me the chlorine tabs they sold me was me mis-using them and that if I only put 2 pucks at a time in the Chlorinator I wouldn’t raise my cya. He claims it goes up only when people put 4-5 pucks in there at a time. This makes absolutely no sense to me, if the cya is in the tab, it’s going to the pool either way right? What am I missing? I’m still converting to liquid either way, due to this forum but now I’m puzzled and want to better understand his logic. All he could respond with was that 1,000s of customers of data is what is proving his point and couldn’t really address my questions.
