I goofed by getting my FC to 22 instead of 16, not worried, I'll just have to wait a little longer for it to drop to the proper closing range of FC 12 before I close.
I was going to test pH & was 99% sure it would need acid per my years of experience. No need to test pH with this high FC, it will not be accurate. I assume it is ok for me to add the expected acid anyways? I always take it from pH 7.8 to 7.6 so not a huge change. Or do you want me to wait a day or 2 longer to add the acid? My CSI remains balanced even if my pH gets to 8.2, so it is no problem if you want me to wait because I'm not worried. The real issue/my real question is does this high FC of 22 actually affect the pH in which case if I add acid I will go below pH 7.6 which I do not want to do , or, is a high FC simply a matter of the ph TEST BEING INACCURATE at a high FC rather than the actual pH been affected by the high FC?.
Secondly I assume there's no way to get the FC to drop quicker except draining some & adding water which is kind of stupid I guess? (I want to get the pool closed before the leaves start falling because it will be a lot more work for me). My closing FC range is FC 12, about how many inches of water would you drain to get to FC 14 (just be safe) or don't even bother just be patient?
Thirdly, at this high FC of 22, can I test for CH & CYA & TA and get accurate readings or would you like me to wait until the FC gets to a different lower level before I test these three? If yes what FC?
