I read this link here:

Diana Walstad talks about using CaCL2 for a Calcium source as it doesn't affect PH.
Ray brought up in another thread of mine that the cloride could be too much of the tank.
According to the Ferilator here in order to get my 5g RO water Gh up to 5.44 I need to dose 4 grams each of CaCL2 and MgSO4.
I have both chemicals here but was wondering everyone elses take on it.
I am reconstituting pure RO water and don't want the PH to go up.
