Is that bad for the filter??? I have heard many opinions about this. The sock method takes too long (in this case I needed to up the CYA quite urgently). The bottle's instructions say to SLOWLY add to skimmer or throw in the deep end of the pool, brushing the floor later so it doesn't sit at the bottom.
