    CYA/Sock Question

    I see alot of the pros on here say that CYA should be put in a sock. The same advice is given in Pool School.

    Ok, this may be a really dumb question but is this like a regular athletic/dress sock or some sort of special pool "skimmer sock"

    Also, do you just open the cover for the skimmer throw it in and let it sit in there??

    Pretty well. I use an old tube sock because it holds more CYA.

    The advantage to the sock method is that only dissolved CYA gets into the filter, so it doesn't clog up your filter or restrict filter maintenance.

    You can hang it in front of a return too.

    I normally use my wife's and then RUN like the wind!

    Sorry, I have too much time on my hands.

    Like JohnT I use a tube sock, cheap and holds a lot.

    The handles on an old bleach bottle that has been refilled with water serve as a handy portable and yet sturdy tool from which you can tie the string/sock combo and place near a return so that the sock hangs in the path of the return water. Also, a weight plate (used on barbells) would also do the trick.

    A good test kit is an investment, not an expense.
