PB who helped install my equipment this past weekend (Sunday) poured 2 gallons of 12.5% chlorine into my pool before I could tell him I have no CYA. Turns out it wouldn't have mattered because he doesn't fully understand what CYA is...
Last night I checked and I have:
CH= fading endpoint around 380-400
The hardware stores that I have stopped at so far don't sell CYA, so I have some tri-chlor pucks that have been running in a feeder and I am trying to get my CYA up to around 25 or so that way.
It is an indoor pool, so I suppose it will take a while for my FC to come down, but does the CC indicate that I already need to shock again?
The Pool Calc says that 2 gallons of 12.5% would have added 16ppm FC to my pool, so from Sunday afternoon to Wednesday night it only went down about 4ppm. There was 0 chlorine in the pool when we started.
