The pool is almost three weeks old now, and it's going well. You have been so helpful.
Early on, we got CYA readings of 50-55. Then, I'd say it read more like 45. We went several days without checking, and now it's more like 35-38.
My husband and I each independently read it the other night and both got 38 (between 30 and 40, closer to 40 end, that's how we got 38).
Since the test is so subjective, I find it hard to read. I'm holding it about waist level, in good light, looking down on it, dropping in slowly until the dot is completely covered. I wonder, though, since I know there's a dot there am I going too far in trying to cover it up? Know what I mean?
Anyway, we either read CYA wrong earlier or are reading it wrong now. Any thoughts?
The pool looks great, this morning's numbers look good:
FC--8.5 (same as late last night, passes OCLT)
CC--0
Ph--7.6
(Last night: CYA --35-38,
TA--80.
Last night around 6 pm, the FC was 2.5 (CC--0). I seem to have lost a lot of chlorine during the day yesterday, since each night I try and take it to 8-8.5. However, we had a record hot day at 102 degrees yesterday. (Water temp was 92, so you can see how hot.)
Bottom line, do you think I should add a bit more CYA? I'm wondering if it needs a bit more to slow chlorine loss.
