What do you guys think about using saltwater live sand in a freshwater aquarium? I have about 100 lbs of live sand laying around, so I might as well use it for something. I'll be cleaning it up real good and maybe let it dry for awhile, then put it in a 55 gallon that is going to be a planted tank. Quite a bit of work is involved so maybe I'll just buy some gravels or new sand.
