    How perfect is that?!

    Chem Geek posted a reference to a CYA slurry which dissolves quicker than granular CYA, Patent 6,207,177. The process involves mixing caustic lye with cyanuric acid.

    So now we have CloroxPro with lye in a bottle and we have CYA in a plastic jar and there's that old five gallon bucket over by the shed . . .

    . . . okay, better not try this at home, huh?

    Before answering, could you tell me if I am a named beneficiary in any insurance policy or trust that covers you? heh heh

    I never did fully get why folks have to wait up to a week to see all of the CYA show up in test results. The Trichlor powder and CYA flakes (not really granules) I use are all fully testable in an hour or two. In other words, there is no further measurable increase in concentration after a couple of hours following application in warm water. Not what most people say on the forums but true for me nevertheless.



    [Edit: Though I have not looked at every single clorox product's MSDS sheet to know this, I presumed that all liquid bleach contained some amount of lye.]
