It's just a 90 gallon prefab pond. We built a cedar box that raises it off the floor. It sits on 3/4" plywood and with slatted sides for good ventilation, since the room has a wood floor. There is a pond filter and pump, a pond aerator, and two of the little pond misters that add humidity to the sunroom, as that's where we overwinter our plants.
