I'm a little stumped that my pool has not returned to previous temperatures after draining and refilling. I had expected to pretty much lose the rest of the summer, but became much more optimistic when my temps were in the mid 70s after the refill was complete. I hoped that I'd be back into the 90s in no time, especially with Indian Summer coming on.
I'm stumped that my temps have gotten stuck at about 85 degrees despite some really scorching days.
Could the higher temps we saw prior to the water change possibly have something to do with the extremely high CYA levels (>200, my motivation to drain the pool) we had before?
My numbers are currently pretty close to where they want to be (though I am fighting to get the TA down).
My current numbers:
FC - 2.5
TC - 2.5
CC - 0
PH - 7.0 (added muriatic acid to reduce the TA, busily trying to aerate the water to bring this number back up)
TA - 140 (still have more acid to add, but don't want to reduce my PH any more than I have)
CH - 300
CYA - 40 (wooHOO!)
With the chemical levels before we drained (CYA thru the roof and NO chlorine) we'd have to leave the solar cover off at times like these because the water got too warm (high 90s).
So... what's going on to keep the pool from reaching water temps we had before?
