Are the calcuations that were documented in 2007 for CSI still valid?
The result differs from my LSI calculation (the CSI tends to be .05 - .25 lower than mine.)
If the CSI calculation is correct, additions of MA to lower pH have consistently pushed the saturation index into corrosive territory… what to do?
In the example below, I acted to lower pH with MA from 7.7 to 7.4
Per CSI calculation, this would result in -0.60 CSI
To achieve a CSI near zero, it seems the right action would have been to increase pH to 8.1
Am I missing something? Thanks.
