calcium hardness

[boscogabby]

Is calcium hardness important in a vinyl inground pool? The pool is about 8000 gal and my latest numbers are FC-7 / PH-7.4 / TA-110 / CC-0 / CYA-60-70 / CA-140 down from 250 from last weeks test. Water is crystal clear, also I am using an Aquarite SWCG. Should this be adjusted?

If you don't have a heater then your lower calcium level will be a benefit since it will cause much less scaling in you SWG! Even with a heater your calcium levels should be fine!
