Thanks for the feedback. I last checked the pool on 1-27-2011:
FC: 4.0
CC: 0
pH: 7.8
TA: 60
CH: 425
Water Temp: 60°F
CYA: 60
SI = -0.4
If I bring up my TA to 100, it will be 0. I also have a SWG @ ~13,000g. It also has a spa that spills over into the pool. Yeah, I have to adjust my pH ever weekend as it can go from 7.2 to 7.8 within a weeks time.
