BioCube Compatible

Upgrade the flow in your BioCube

You have options when it comes to adding the Random Flow Generator to your BioCube aquarium. You can add a single 1/2in Flex-Series RFG nozzle or dual 1/4in setup with our Ultimate Nano Tank Return Line Upgrade Kit.

The single 1/2in Flex Series RFG Nozzle is directly compatible with the stock fittings, however we do recommend our Biocube adapter for additional adjustability.

Choose the adapter based on your brand BioCube you have. Oceanic brand uses the 18mm while the Corelife brand uses the 20mm
