    How to add CYA?

    Please always start your own thread, thanks. Butterfly


    Don't mean to hijack the thread, but is there a reason for adding CYA through a sock hanging in front of a return? I've always poured it into a skimmer slowly.

    Re: Liquid Stabilizer vs Dry

    I have in floor cleaners. I just broadcast stabilizer over the whole pool while the pump is running and it disperses fairly quickly.

    Keeps it from staining the pool surface.

    If you do it that way it gets hung up in the filter and takes longer to dissolve. Could also get back washed out. The sock method is the preferred method. 😎

    I would advise against broadcasting cyanuric acid. It does not dissolve quickly enough.

    Just added 4lbs through some panty hose in the skimmers and it took about 4 hours. Just a little massaging the hose to get it all dissolved.

    Re: How to add CYA?

    I usually just add some pucks to the floater when the CYA is low but on the few occasions I added it from the bag, I just slowly poured it into the skimmer. I have a cartridge filter and have never had any issues dosing it this way. I would be reluctant to simply broadcast it because it does not seem to dissolve too well and I would worry that it would sit on the bottom and bleach/stain the surface.

    Supposedly you don't want to rinse you filter for a couple days after you add CYA (because it takes a while to dissolve) so if you're due for a filter cleaning then do that first.

    We have also seen a couple of reports where it appears that the CYA poured into the skimmer ended up clumping and clogging the pipe. Using a sock is safer.

    You have in-floor cleaners, which keep the acid from sitting on the floor. However, most people do not have in-floor cleaners.

    In any case, I don't think that broadcasting cyanuric acid is a good method. I don't think that it is a method that should be presented as an acceptable option.

    Re: Liquid Stabilizer vs Dry

    I broadcast the CYA once, and my Polaris collected it all in its little bag. Poor thing was so heavy it was falling over on its side.

    Now I get the more expensive liquid CYA.

    Why? Seems like a waste of money when an old sock in the skimmer or in front of a return jet would work fine.

    The granular stabilizer is just as good and cheaper. You have to add it the right way. The sock, knee high method in front of a return is the preferred method.

    It is an acid, so it could fade the pool surface.

    Re: How to add CYA?

    You should not run the Polaris after you put in the CYA. Just like you shouldn't backwash a filter. Give it a week to dissolve.

    Re: How to add CYA?

    I will note that different brands of CYA dissolve differently. I found the brand from Walmart, HTH, was super fast to dissolve. In comparison the brand from the pool store (name not recalled) was super hard and took quite a long time to dissolve. The HTH was almost fluffy compared to the hard rocks of slower dissolving sort.

    There is no reason not to run the Polaris when adding cyanuric acid.

    Was there a difference in the size of the granules?

    I've had the same experience. If I recall correctly, the Walmart HTH brand seemed to be more "flake like", for lack of a better term.
