Thanks for the responses. The issue with the Pool Pilot was last year. As soon as I got around the 500ppm level, the unit began generating chlorine again. It was the first question that the Pool Pilot tech asked me while we were on the phone discussing the issue.

As of 11-10-07:
FC = 1.8
CC = 0
pH = 7.6
TA = 90
CH = 500
CYA = <20
Salt = 3000
water temp: ~60°F

The water is crystal clear. If you were to throw a quarter in the water, you can tell if it's heads or tails. Looks like my CYA is too low. I believe the correct range is 60-80? If I was to use triclor tablets, that will raise the CYA correct?
