Update and a few questions - Reading tonight as it has been holding well since did the drain and 8.5 gal bleach . Tonight PH 7.8 FC 3.6 CC 0 TC 3.6 ALK 140 HARDNESS 140 CYA around 60 All tested with Taylor kit. So what do I add under BBB to raise hardness or domt you worry aboyut it at this level? Would you do anything to adjust AlK a little or leave ? I am using between 3 qt and a gal of bleach a day to keep FC above 5 . Is this normal as at this rate the bleach is about $1.60/day or $48/month ? Would a SWG be less expense to operate ?Water has been excellent
