I appreciate the replies. In light of a clear pool, every reading I have out of normal requires dilution to correct. High CYA (100+), high Calcium Hardness (600), and Total Alkalinity (175, but down from 250 after first partial dilution). Still two months to go in the pool season here, so I'll try a 50% drain. Fill water is essentially 0 FC, .8 CC, 80 Calcium Hardness, Ph 8.0 and TA 70. A shock after refilling and maybe the FC maintenance won't be so high? I'll bite the bullet......
