Moved from here.. Calcium Hardness
I was excited to see someone else ask this. I also have considered asking this and want to add a question... what about the overall saturation index in deciding those limits for Calcium Hardness? We filled a new Plaster/pebble pool in December with really high initial TA, low CH, but maintained acceptable saturation index between -.3 and +.5. My CH is now at 230 due to soft fill water (autofiller) But I am hesitant to increase CH because my saturation index is still good. I anticipate as the temp warms up in summer I will need to address it though. Thanks!
