My CYA was 100 last week (When I say 100, I lost sight of the dot right when the water line hit 100 so I'm somewhat confident that it is truly 100 and not higher than that.
I dumped about 1 1/2 - 2 feet of my pool water and refilled using garden hoses.
Checked CYA today and same thing, 100 (dot disappearing right as the water hit 100)
Either I am wrong an my CYA is over 100 or something funky is going on. I figured dropping that much water out would at least get me to around 90 or even 80.
TA: Fault due to high chlorine
