    Water Temperature

    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...

    I think you are taking the CSI number WAY too literally. There is no way a 3 degree temp change causes a problem. From what I see that would only change the CSI by 0.03 .... If you are not less than -0.6 or greater than +0.6 you should be fine.

    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.

    82 was temp. I think it might of been a glitch in the pool pal, the temp portion was the only thing that was different. Thanks

    And it would be wrong to suggest making such adjustments. Especially based on just this information. Just because the temp drops does not mean the water is suddenly detrimental to the plaster based finish.
