Ok - I'm really obsessing over my CH. We replastered the pool this January partly because our CH was through the roof and we had to drain it anyway (I'm sure previous owner never drained for CH). We have hard water and after almost 6 months after replaster are already up to 450 CH. My fill water is 100 so my CH is just going to keep rising as we top off the pool twice a week due to evaporation. Does anyone have any experience with a water softener? Can you get them just for the pool fill and are they hard to install? What are the drawbacks of using a water softener for pool filling?
I'm trying to decide it it's worth it to me to get a water softener and not obsess about CH or obsess about CH every week when I do the testing. Honestly, how high is too high of CH before it's unmanageable and you must drain?
