Calculate the Saturation Index, test for pH, temperature, calcium
hardness and total alkalinity. Find the cooresponding values in the
chart below and enter those into the equation. Accepatable values
are -0.3 to +0.3, ideally 0.0 to +0.3.
Note: Take your value from each column. Match you temperature to get TF, Your Calcium to get CF and Aslakalinity to get AF |
