Hello all
I recently had a utility sink put in my basement so I can get hard water that bypasses the softener. I took a GH reading from the hard water in the new sink and it went from 1 softened to 17 hard. The PH has not changed, still at 8. Do you think it is safe to do a 50% water change when the GH has changed but not the PH?
