    Adding CYA at start up

    Hello. We just got our pool set up and in reading through pool school I missed that the cya is supposed to be added by dissolving in a sock. Long story short we just poured it in all along the edge. Should I be vacuuming it back up and starting again or will it pretty much dissolve by morning?

    Welcome to TFP!

    At this point, you should vacuum it up into the filter and let it dissolve there. Leaving it were it is could damage the pool surface.

    Thank you! My filter is not attached to my vacuum. I have just one of the ones that hooks to my water hose. I'll go ahead and vacuum it up and then should I just empty it out into the filter? It said in the instructions to put it into the skimmer and that's how we ended up just pouring it in, because we don't have a skimmer either.

    In that case, you can put it in a sock, or in the filter. Using a sock will probably be simpler.

    Just vacuum it up and then unhook the vacuum bag and tie it shut and hang it in front of the return stream to dissolve.

    Thank you @richard320. That's what I ended up doing last night. Thank you everyone else for your help.

    One last question: how often do I add cya? Just each time we add new water?

    No.

    CYA, like Calcium, doesn't evaporate. The water goes away, the CYA stays. So the only way it will drop noticeably is through draining and refilling or splashout. Once you get the level set, you only need to check it once a month or so.
