We had a small crack in plaster and had to drain the pool for repairs. Refill was about 95% of capacity with city water.
I'm using the TF-100 kit to assess levels and Pool Math to establish targets, and SLooooowly raising factors. I'm maintaining middle of the road PH while running high Chlorine to keep algae in check. Overnight drop tests have stabilized, so Chlorine will be reducing.
Numbers:
Start.....................Current................Goal
FC = 0.....................16.......................4
CC = 0......................1.......................0
TC = 0.....................17.......................4
PH = 7.8..................7.5....................7.4
TA = 70....................90....................100
CH = 40..................140....................300
CYA = 0....................50.....................70
Salt = 1800.............2800.................3000
Notes: TA and CH: I intend to run these at top end of the recommendations to produce a CSI of -0.45. If I push the CH to 350, the CSI goes to -0.38 which feels like a happy place to be.
CYA: SWC is ready to operate; Water Temp is 65*, so reading may be a bit low. I'm raising this slowly, with one-week time between measurements and additional dosage. That should keep me from overshooting.
Salt: Salt was balanced, but we had major storms here a couple of days ago and it diluted the salt concentration. I'll bring it back into line once the TA and CH are where I want them.
Would appreciate any comments/guidance (including, "Oh, gee, don't"), especially the limits chosen for TA and CH.
Thanks, in advance.
