I would switch to bleach, that will stop the problem of it floating to the top. What is your CH? It's entirely possible that the CH has gotten so high that it just won't dissolve anymore.

Are you pre-dissolving it in a bucket of water before adding it to the pool? Have you tried pre-dissolving and then adding it through the skimmer instead of straight to the pool?
