First, I want to say I am so thankful I found this board! I love learning how to be in control of my pool!!
My CYA is high, about 110. I bit the bullet and am doing a partial drain today. My handy husband (who by the way is clueless about the chemical balance since that is my job) hooked up some PVC so I am using the drained water to soak my lawn hopefully the chlorine doesn't hurt my lawn.
I have switched away for TriChlor to liquid. I still have lots of tabs left. How much CYA is released per tab? If I let them sit around and use them slowly over the next 6-12 months won't they lose their potency? I'm wondering if I can leave 1 puck in the floatie just in case the chlorine level drops?
