INTERNAL OVERFLOW SET
professional,quiet and excellent internal overflow box for aquarium
Features
Wavereef Internal Overflow set is a complete overflow and return system for your aquarium. Great for use with sumps, refugiums and wet-dry filters. The unique design allows for the overflow system to be installed on the back of the aquarium so there are no holes at the bottom of the aquarium; eliminating the risk of catastrophic water leakage possible with conventional overflows. Additionally, the whole set takes up a very minimal amount of space inside the aquarium so it maximizes the amount of room inside your aquarium for your fish and corals and does not distract from your aquascape. Its special construction makes the overflow system very quiet and generates a wave effect on the water surface.
