Overflow and spillway

Two Water Return Systems

Discover our high-quality overflow systems that allow water to flow down from the aquarium without drilling the glass. Through an external circuit, the overflow is a great way to pump water to the sump without additional work on the aquarium glass. Alternatively, opt for our overflows, which provide slight pre-filtration through ergonomic combs and allow water to flow from the bottom of the tank. However, this method requires prior drilling of the bottom glass pane.
