CYA was totally dissolved from the sock both times I added it w/in 24 hours. So I pulled the sock. So are you saying it takes time to actually dissolve in the water and show up? I just changed my filter yesterday as it said to wait 72 hours after adding CYA. I got the Unicel replacements yesterday so was eager to get it changed.

I should have worded my ? better. What I meant was- is the reagent only available online or have others seen it in stores. Sorry. Of course I can do my own leg work and didn't mean to imply I wanted/needed someone to find it for me! lol
