A friend bought a clean up crew from reefcleaners and had it shipped to my place since he went out of town. It shipped on wednesday and got to my house on friday, but I was out of town and got home saturday evening. I picked up the package and went straight to his place, floated the bags, and tossed them all in (this was what was suggested by reefcleaners). A majority of the snails made it, a few did not but he gave a bunch of extras anyways, lol. In short.. snails in bag of little water for 4 days, float bags, dump in, still okay!
