Marine Sources Siphon Overflow Box hangs over the outside of the aquarium. Water circulation is achieved by pumping the water from the sump into the aquarium, and then via the overflow box back into the sump. This makes it possible to connect aquaria to under the tank filter systems without having to drill holes in the aquarium. The overflow box is manufactured from high quality acrylic and is available in two capacities:
SOB-1 for up to 2,500 l/h (c. 625 gph) (L/W/H):18.7*19.7*26CM
