Hello all.
OK, I drained about half the pool and refilled (just reached full level this afternoon). The results, below, are from a couple of hours after reaching full (wanted to get a 3QT jug of bleach in it and let it circulate for a good hour. Circulated in filter bypass mode) Did the trick on the CYA but PH is really high (I'm assuming city water is high in PH). I'll do the research to see what needs to be done, but I wanted to post for advice to check my research and not screw this up. Help highly appreciated.
PH: took 3 drops of R0005 to balance
Chlorine: 1.4 ppm. Low. Added a 3 QT jug of liq bleach yesterday and another today - so 6 QTS in 2 days. Will add more tomorrow.
TA: 50ppm (good)
CH: 110ppm (low - quite surprised as our city water is very hard, or at least I thought it was). This # was 400 before drain/refill
CYA: 40ppm (perfect)
Thanks again for help
Cheers
p.s. After doing above test I let it circulate (filter bypass mode) a couple hours longer before applying the DE (I had backwashed while draining the other day)
