START UP: Keeping CL up

Probably better to hang it in the sock in front of a return jet. I think it will dissolve faster with the constant stream of water going at it than having it just floating around the pool.

Or to put the sock in the skimmer, but make sure your pump has alternate places to get flow so that the skimmer doesn't get clogged (my skimmer has an alternate port going into the pool, plus I also have floor drains).
