I have had high CYA levels and have gone to liquid bleach. In the mean time I was going to get the CYA levels corrected when I started up the pool this year. I have the suggested Taylor test kit (FAS-DPD chlorine with R-0013 CYA reagent)and thought I would check the CYA levels to see where I am. CYA doesn't even show up at all. Last year it was running 80 - 90 or so. BTW, Walmart has 10% Pool Chlorinating Liquid (bleach) for $3.24 a gallon.
So, does CYA go away over the course of 5 months ???
