why does the temperature of water have an impact on the balance? The temp dropped to 79 pool water, it now shows corrosive to plaster, at 82 it doesn't..Is there something I need to do to adjust for water temp change? Thanks for the great support...
it now shows corrosive to plaster, at 82
Do you mean -0.82? Sounds like it was corrosive to start with if it changed by 0.03.
I believe I would do a little adjusting if I were you.
The biggest difference water temp has on CSI is from summer (when the water is the warmest) and winter (the water is coldest). 3 degrees wont make much difference but when you look at CSI with 90 degree water and then with 40 degree water then you can see the difference.
