    Another CYA Question...

    I have read all this talk about putting CYA in a sock, but what is the big disadvantage of just sprinkling the granules in the pool and brushing it around? Will it discolor plaster (PebbleTec)? Hope this isn't too much of a newbie question.

    CYA is acidic and dissolves very slowly. If you leave CYA sitting on the bottom it can erode the plaster that holds the pebbles in place.
