- WATER FLOW
- Hang On Back Reef Overflows
Hang on Back Overflows are a great option for an aquarium that does not have an overflow built into the tank, and you want to utilize a sump for filtration.
We carry the AquaC and Octopus Overflows. We recommend when using an overflow box that you also purchase the Aqualifter pump to keep the syphon going in case of power failure.
