A friend of mine is thinking of selling his 150 gallon tank. It's got fish in it now, but I suppose one of us can trade them in at a pet store and save the extra stuff in case either one of us wants to have fish again. It's set up as a saltwater tank, though. Any ideas on how I can purge the salt and decorate this huge tank if he decides to sell it I decide to buy it off of him?
