I have a quick question about my pool chemicals. I have an above ground pool as you can see from my signature below. All of my chemical levels are on point except for the Calcium Hardness. I know this level doesn't matter much for above ground pools. My level right now is 100 but wanted to see if that was OK or if I needed to raise it any. The water clarity is crystal clear just wanting to make sure of the next step. 2 months ago it was around 200, so it has fallen about 50PPM a month.
