Hello! My first post.. We set up our pool in mid July. All has went pretty good. Very happy with the set up. So my only issue I am having so far is that I have over shot my CYA a bit. I tested tonight when I got home. CYA was 65 FC 8 and CC 0. So I would like to be more like 35 on my CYA and 5 on my FC. I dumped about 6 inches of was which should be around 1600 gallons. I refilled with fresh tap water (city water) that shows no CYA really at all. I just rechecked the levels and really didn't see a change. So my question is should I keep at it weekend dumping water. Or does it take time for the change to show up? Should I do a larger change tomorrow? TA is 100 and PH 7.2-7.4
