It is 4feet x 4 feet square and then 21inches deep. I think this is about 212 gallons. The filters are from left side of picture around the back: Aquaclear(AC) 300, white tubes are a custom filter through a small pool pump, then the pick up for the wet/dry, then on back a AC 500, UV sterilizer, another AC 300, and a powerhead 400gph with a foam pick up.
