I have an 18' round AG pool with 54" walls.
I have added a full 2 lbs of CYA using the panty hose tied in front of the return jet method.
Pump/filter have been running for 3 days; 24 hours a day.
I have tested water 3 x using the Taylor K 2006 and can not get the CYA levels to go up at all. My water is sparkling clear, but I think it's because I'm dumping in ~1 gallon every other day of Chlorox.

Is it possible that my jug of CYA was bad? Help? TIA!
