I put mine (CYA) into a knee hi and tied it to the outside of the pool but dangled it right in front of a return. It dissolved in about a day. I'd just reach in from time to time and mush it around in the knee hi and it worked like a champ.

Guess I'm going to have to go on a cheap Knee Hi quest. I never wear the damn things anymore, so I only need them for the pool.
