The current tank system consists of a 50 gallon display tank connected to a 50 gallon refugium and sump combination.

Water leaves the main tank through a 1 1/2" PVC standpipe. Gurgling noises are prevented by using a 90° elbow and a "T" to raise the water level inside the standpipe to just below the water level of the tank. The "T" also allows any trapped air bubbles to escape and keeps the water flow silent.

The water then enters a propagation tray made from a plastic sweater box. It then escapes through two bulkheads into the refugium, then overflows into the sump chamber where the return pump, heater and protein skimmer are. From there the water is sent back to the main tank.
