I'm pretty good with my pool after hanging around here long enough but I'm trying to help my inlaws with their hot tub (455 gal Sundance Altamar).
I brought my TF100 out and ran these numbers:
FC = 0.6
CC = 0.2
TA = 40
pH = 7.2
CH = 250
CYA = 0
My mother-in-law uses Dichlor and just threw about a half a cap full in this morning. A cap full is 2 ounces by weight, so that should raise the FC to 9 but it's almost gone and no one has used it.
So, my question is do the same rules apply for cya/fc and shock levels? And does she need to worry about that CH level? Or does this just not need to be that complicated - can she just shock the Crud out of it for a few days straight and be done with it?
