Thank you for the reply pooldoc.

I do have a test kit, but not sure its a Taylor one. Ill check tonight. It does have 5 or 6 reagent bottles in the kit, so I believe it can test more than just pH and chlorine.

The test on the pool water I got yesterday at Pinchapenny (they do use Taylor equipment as I checked) showed----

TC = 3.0ppm
FC=3.0ppm
CC=0.0ppm
pH=7.8
Acid demand=2
Base demand=not tested
TA=110ppm
CH=200ppm
Stabilizer=100ppm
TDS=1000ppm


With what I know about pool chemistry (which is little but I am learning quickly by necessity!) the stabilizer (which I believe is CYA) is rather high compared to what most folks on the forum seem to run? And higher CYA typically means higher FC is needed? So, if I can get the stabilizer lower, I can run lower FC?



You are in Florida, so I'm guessing your pool is concrete? If so, you *probably* can drain and refill it safely, if it hasn't been raining too much. But, you aren't ready for that, yet.
Yes, its an "old school" pool from ~1980, but was refinished with some type of quartz finish ~3 years ago. Its not the Pebbletec or Pebblesheen finish, but something a little smoother. I think it might be Marquis or something like that.
