PB turned the pool over to me 2-3 weeks ago. At the time CYA was 90 and I was burning off 3-4 PPM of Chlorine each day. I had the Chlorinator turned way low and was adding bleach to compensate for the loss in chlorine.
As soon as the PB left, I took the Trichlor tablets out of the feeder and have been using 10% bleach daily as the only source of chlorine since.
We've had several big rain events over that time, totaling more than 24" of rain. Throughout, I have continued to test and add chlorine and MA as needed, but I've also noticed a lowering of CYA, which I assumed was Due to so much rain.
Lately I've noticed bigger losses in chlorine than before (5-6PPM/day loss) and when I checked CYA today, I'm reading only 40 PPM (really, just over 30, but am rounding up).
Is my CYA too low? My rectangular pool runs east-west and gets full sun all day (when it's not raining)
I was thinking of adding a Trichlor tablet or two back to the feeder to supplement the bleach and add some more CYA back. Is this ok to do? What CYA level should I target?
