pH 8.2+ (could this be number invalid due to the high chlorine count? it was just the most purple I've ever seen it)
FC 25-28/CC 0 (PB dumped chlorine in it and I was surprised the CC is ZERO but it sill surely go up as the chlorine kills the algae)
CYA <20 (literally I had to fill the bottle to not see the black dot - I did it TWICE to verify, doesn't shock me because last year I kept it around 30-35ish)
The pool is a green swamp (though the chlorine in there is already doing wonders).
So I am assuming I should try to both raise my CYA slowly (at least get to 30) in order to stabilize the chlorine as I go through the SLAM process to as well as add some acid to lower my pH to 7.2-7.5ish and perhaps raise my TA by 10-20 points to avoid pH sway.
Does that make sense?
Also, how do I use the PoolMath page when my CYA is SO LOW?
