Ok so I think I have my CYA to high, I hadn't checked since I topped it up when I opened the pool 1 month ago and today I got a reading of 70, my goal was 40? oops! I am afraid I have goofed up. Pool looks great haven't had any problems so far and we have swam several times. It has been rather rainey so we have been draining alot. Should I just adjust my Chlorine levels based on your CYA chart under pools school?
