Hello to all,
Have 14.5K gallon in-ground.
Just did the following tests:
FC - 5.5
CH - 225
TA - 80
CYA - 50
pH - 7.5
temp 59-60 degrees
That came up pretty bad at -51...
I added both CaCl2 [16-20 cups of pellets by vol] & NaHCO3 [2lbs] and waiting to take readings again...
With a CSI of -.51 [knowing ranges of .6 to -,6] are where you want to be, 0 as ideal, what kind of things can you expect to happen in pool? My light brown travertine water tile seems to be hazed up and lighten some...mainly on the side w no sun exposure...
thanks and pls advise,
tstex
