    Does granular (HTH brand) stabilizer/conditioner "go bad"?

    I've been putting it in for a week now, and I STILL do not show any on my tests. I don't know the temp of my water - we don't have a thermometer right now - but it's pretty cool yet, so I don't know if that's affecting my results. I'm using Stabilizer from who knows when - the old owner left it here and it was left in the pool house all winter and summer last year. It could be even older than a year!!!!

    My water LOOKS great though - but of course it's all brand new water from the city - which is good for this newbie pool owner and BBB trier!!!

    Hey, Cheryl,

    As always, we need test results to have an educated opinion. I realize your FC tests zero but looking at your other numbers gives us the info we need to help.

    Actually it's the CYA that's reading zero.

    It can take a while for CYA to show up on the test, usually we say to allow a week after adding it. If you've kept adding some all week, stop and give it a few more days then test again.
