Marine Aquarium Fish Tank Sump Water Overflow Box - Two Sizes - SOB-01 / SOB-02

Item Description
Sump Overflow Box by Marine Sources
SOB-01 / SOB-02

The fantastic Marine Sources Siphon Overflow Box is designed to hang over the outside of your aquarium, enabling water to be pumped directly from the aquarium back into the sump, eliminating the need for drilling messy holes into your aquarium. Water can be pumped from the sump into the aquarium, and then via the overflow box back into the sump.

Each unit is designed to reduce noise and features a removable safeguard comb to prevent your fish from entering the overflow box. Dual air-draining tubes can be connected to your Marine Sources skimmer air-silencer dual nipple to enable air to be sucked out faster and more safely.
