I'm planning on building a new reef tank for my living room in a 125 gallon 72x18x22. I've always loved when the navy sunk's a retired battleship or cruiser to how build new reefs in the ocean. So i'm thinking of doing the same thing, but just on a smaller scale. I don't want to hurt the fish or coral with just adding a ship without sealing it off. I guess i'm wondering if anybody has made something for a saltwater display and not had any issue's.
