2200x500x600mm (LxWxH) sump. Water flows in via two 50mm drains, one with a ball valve set so it runs at a full siphon, then into a settling chamber to collect the heavy waste (nothing in there as the tank only got it's first fish today), then through four sheets of Poret foam, then through 20L of Pond Matrix and some ceramic rings, then over five 300W heaters before being returned to the tank by a Laguna MaxFlo 11000 pump with 40mm plumbing. The details of the tank can be found here; http://www.monsterfishkeepers.com/for...
