Thread: Adding a lot of dry stabilizer

    Adding a lot of dry stabilizer

    My buddy has a pool similar to mine, except its 25k gallons and not 30k. He needs to raise his CYA 30 ppm, and that would be ~6 pounds of CYA. The instructions just say to add it to the skimmer but I was curious if there was a "better" or more correct way to do so, and also how much should he add at a time?

    It is fine to add it to the skimmer but you should not backwash for a week so you don't flush out any undissolved CYA. Many here on the forum put the CYA in an old sock and tie it off in front of a return and let it slowly dissolve. That way, you have backwash capability. Either way works.

    Alright good deal, we just cleaned his filter so its good to go.

    And about adding 6 pounds in, all at once, or what?

    Not in one Giant PLOP, of course, but all slowly into the skimmer or all of it in a sock, yes.

    Ok sounds good, thanks for the help. This is honestly one of the most helpful forums I've been to.
