A bit of background
I have very hard water. The fill water CH varies between 150 and 250. Evaporation rates can be an inch or more daily during the summer. Pool stays open and uncovered year round. The net result is my CH levels get very high. My current CH current level is 1,050. I have thus far used what I have learned here to keep my CSI at or near zero and my pool scale free. But as the CH get higher that becomes more and more difficult.
I have scheduled an RO treatment of the pool, with a goal of bringing my CH under 100. Once this is done, I am considering having my pool's auto fill supply moved to my water softener output.
Good idea, or not?
