Thanks Waterbear,
I had put my readings in the earlier post I had edited. I added another bottle of sequestering agent last night (supposed to treat 20k gallons, I have 18k) I do think it looks a little whiter this morning. Here are my readings, the only change seems to be the CYA. FC=1.5; CC=0.5; TC=1.5; pH=7.4; ALK=70; CAL=30; CYA=100; TEMP=85. Will I need to add sequesterant on a regular basis to prevent staining?
Again thanks for your help.
Marty
