I use Instant Ocean and I know many other crabbers do as well. I have never had a problem with it, but that is just my opinion. There are a few places for shells online I know of, and they are the crabbagepatch.com, Naples Seashell Company, El's Shells, just to name a few. I have found most of mine at Michael's and other craft stores and they are normally cheaper as well. Anyway just some suggestions.
