    Where did my CYA go?!~

    So my pool was low on cyanuric acid...so i bought some today...put it in an old tube sock and tied it extremely tight to the frame of my pool in front of the return. Went to check on it before bed...and its almost totally gone! I have almost 4 cups of CYA in that sock and there is barely any left...i see no holes in the sock and looked very close at the bottom of the pool and couldnt see any granules there. Last time i put this stuff in a sock like this it took forever to dissipate...the the cya acid goblin get me or what?

    Should I even be worried?

    Is it the same brand of CYA? I find some dissolve much faster than others.

    Man, if you have a CYA goblin you need to be very careful. They tend to be in league with the leprechauns. I don't mean the happy lucky charms kind, I mean the evil Warwick Davis type!

    Luckily it most likely just dissolved faster than you expected. I have had it dissolve in a few hours before and it showed up on the test later with no problems. No worries! Unless there is a goblin... then significant worries...

    I recently added 4 lbs in a sock in front of the skimmer and within a few hours( 3 or 4 ), it was pretty much all gone. Mine was purchased at Walmart as well.

    HTH CYA from WallyWorld gets great reviews. Some even say it is more powdery and dissolves faster.

    I use Leslie's Chlor-Brite granules and can dissolve 1# in a tube sock in about 2 minutes. I just hold it in front of the return and away it goes.

    I don't think that is CYA, that's granular chlorine.

    Yeah, that's dichlor. It will increase your CYA but doesn't need to be put in a sock. You can just slowly pour it in front of a return. Pure CYA takes longer and so needs the sock treatment.
