Ok, I've learned a lot at this website, but for the life of me I just don't understand the purpose of keeping CYA so low, and not using trichlor. What is the biggest problem with having a cya so high? Every single person I've talked to, even including the guys that run Wet Republic Day Club here in Vegas. They use liquid chlorine, but the guy says he just uses pucks at his own house. I asked him about cya, and everyone says that you have to replace the water eventually anyways every couple years. Can someone explain this to me in simple mans terms? What is the harm? I just don't understand for some reason.

I have no problem pouring chlorine in every day, and monitoring it myself, but the simple chlorine test for me it's hard to tell what my actual chlorine level is (based on how yellow it is). Right now I'm using leftover trichlor pucks to get my cya up above 20 since my refill. I've checked it every 4-5 days and it's still low, so I'm not too worried right now. Pool season is coming quickly, and I'm aiming to be an expert by April.
