This is a 48" x 18" @ 13" tall 50 gallon tank divided in half... The background and other 'rock work' is styrofoam sealed with tinted Drylok... The log is styrofoam covered with colored silicone... water pumps into the top right corner and runs down the 'rock' face, flows through the 'river'. The left side of the tank is drilled where the water falls down into a sump.

This is part of a larger set up that is not quite complete. When finished this tank will sit on top of a 75 gal terrarium/vivarium that has a resevior which acts as a sump for both tanks.
