This huge tank has a large sump with a total capacity of about 56 (67 US) gallons.

The tank has two large weirs, one in each back corner, which have been constructed from a single pane of glass at a 45 degree angle to give a smooth angled corner shape, rather than a square weir tower - which means there are no 'sharp angles' in the tank that the catfish could scrape themselves on. The Leiarius pictus had demonstrated a habit of messing with filter pipes, etc in the past - hence a sump filter seemed like the best idea for several reasons!

The actual output of the pumps at the head height will be lower, about 2500 LPH, which is still enough to turn the tank volume over more than 3 times per hour. The system is plumbed together with marine-grade PVC pipework, with valves in the return lines to control flow if required.
