I opened about a week ago. The pool was pretty clear and just a little green on the steps. I added five gallons of 12% chlorine and got the pump running. Not much debris thanks to the safety cover... mostly dead worms. I ran the Polaris and that took care of most of the stuff on the bottom.
A week later, my pool is clear and blue. The water looks great. I took a sample and here's my numbers:
FC - 1.0 ppm
CC - 0.0 ppm
Ph - 7.4
TA - 60
CYA - 0
For some reason, my CYA is always 0 when I open (or non-detect, which I think means it can be up to 20 ppm). Anyway, I have left over pucks left from the prior owner. Should I just use those until my CYA comes up? Is there a danger in doing that? I know my FC is low, but with my CYA so low, I think it's sufficient.
