Hi folks:
Just wrapping up our second season with the pool in our new home. Its a 40 year old Gunite pool.
Overall, this year has been relatively easy. My FC, PH, CH, and TA have been pretty much in range all season with just a few minor corrections here and there.
I did a full test of the pool today (except for CYA.) And here are my results:
FC: 9.5 (A little high as my pump timer had been mistakenly left on for the past 3 days.)
CC: 0.5
PH: 7.5
CH: 400
TA: 50
Salt: 3200 ppm
Temp: 80 deg
I'm pretty much right down the middle / in the target areas for all of the values except for TA which is a little low.
Imagine my surprise when I punch all of the above into PootMath and it says by CSI is -0.63 which gives a warning that it is likely "corrosive to plaster."
I've never really paid much attention to CSI. How critical is it and why is it I may have a problem if most of the values are in range except FC being a bit high and TA being a bit low?
