    Adding CYA

    I snuck this question in on the end of a reply on another thread, probably should have just started here...has anyone ever used one of those chlorine tab floating dispensers to get CYA into the pool? I'm still gonna put it in a sock, just thought it would be a cleaner method.

    It's generally too time-consuming to add a sizable dose with pucks.

    A floater (pucks) might be OK to change your CYA by maybe 10 ppm or so but that's about it.

    Re: Adding CYA

    If you mean to put the sock in the floater, instead of a puck, it might work. I say might because I've never actually seen the floating housing people put pucks in. Hanging it off the wall is fine, though, so not sure why you want to do that. Or, when I don't have circulation due to the pump being down (such as the last 8 days with a pool full of water), I've hung the CYA sock on a piece of string from a pool noodle or water wing, or anything that floats.

    I guess hanging it off the wall will do...just looks a little ugly. No worries, though...so does the owner.

    Hopefully you mean you will put powdered stabilizer in the sock. If so, it may look bad, but not for long. It will saturate fully within a few hours. After that you can squeeze the sock and it will disperse in little clouds into the pool.

    Re: Adding CYA

    Yes, that's exactly what i was referring to. Like I mentioned, I was just thinking of a cleaner way to do it...actually last year I hung the sock inside the skimmer lid...making sure it was secure and wouldn't fall fully into the skimmer. Even thought the basket would catch it, i was worried that somehow it would clog things up if the sock fell into it. The extra turbulence in there seemed to help the CYA dissolve faster.
