Here's my numbers after fighting an algae growth:
FC - 18
CC - 0
TA - 110
CYA - 40-50
CH - 700! (tested it twice to be sure)
The pool was clear until about a week ago and had to shock it. I used liquid chlorine (10%) and 1.5 lbs 48% cal-hypo shock. When I got my TF100 in June ,the water was already at a CH-400. The 1.5 lbs of shock was the only thing I've added since that has calcium. Until last week, the only thing I've used on the pool was 6% bleach, 10% liq. chlorine or Muriatic acid. Would any have those raised the calcium that much?
The algae is gone but the water clarity isn't where it was before the algae outbreak. Could this be Calcium precipitate or is it algae debris? Should I do some partial drains to get CH down?
The pool calc. says the CSI index is at -0.01. Is this bad?
