When I used Cal-Mag it would raise my PPM. My tap water is usually around mid 70’s PPM It would raise it to about 250 PPM’s It didn’t affect my Ph any

I don’t know the answer to your question. Have you tested the pH before and after adding Cal-Mag? It seems that would give you the answer that you seek.

Yeah , you will need to adjust accordingly after checking PH . For example cal-mag will drive my water ph down a small amount. Good luck
