The wide, shallow 31-gallon Lagoon shape spreads light across the sand bed and gives corals room to spread out, and the low-iron front and side panels keep the view crystal clear. It comes ready to run with a return pump, plumbing, a filter sock, and a leveling mat. Add a matching Artika cabinet stand, or run it on a stand you already own. Want more room?
