Second year with my new pool, which we had built in Fall 2023. It’s about 19k gallon plaster with SWCG.
We’ve kept the CSI in check through all seasons, with it typically running low (around -.20) in winter, but never lower then -.60. The only calcium deposits we’ve noticed are in the SWCG. Today, I noticed two spots and both seem to be just below a chip or crack.
What do we need to do to prevent further chipping? Should I fill these now? Am I running too low CSI?
FC 9.0
CC 0.5
pH 7.6
TA 80
CYA 70
CH 425
Salt 3200
Borates 56
CSI -.21
Temp 77*
Thanks!
