Let me post my numbers first:
FC. 8.5
CC. 0
Ph. 7.8
TA. 100
CYA 70
CH. 180 (Using Taylor test kit)
OCLT done several nights and may use .5 at the most, so things seem good there. Water is sparkling, crystal clear. During the day I wil lose 4-5ppm chlorine. This seems like a lot of loss considering how high my CYA is. I am draining and adding water to try to lower my CYA. I like to keep it around 40. (I am testing before adding a bunch of new water, then retest once I'm done adding water and add chlorine to bring it to proper level overnight). Last year, keeping CYA at 40, I would only lose 1-2 ppm on full sunny days. I know my Ph is on the high end of the good range, it just shot up from a hard rain yesterday. My well water Ph tests at 7.2, so I will retest Ph after I'm done adding water today and see if I still need to lower it a little. Am I being overly critical here, or could I have some kind of problem brewing?
