So I’m always a bit confused about how, or if I even need to, correct CSI. FG. Today’s test results (logs are viewable):
FC 10.0
CC 0.0
TA 60
CH 275
PH 7.4
CYA 80
Temp 89
Salt 3200
CSI -.62
Could bring CH up a little, or TA, but that doesn’t do much. Could raise PH a little but hate to mess with that, it’s always pretty solid between 7.5 and 7.8. I never have to add MA.
I see conflicting info which says CSI should be either higher than -.6 or higher than -.3.
How should I adjust for CSI or should I even bother?
