The external Hang on Box by Finnex is a must have multifunctional aquarium add-on for those with limited space. This space saving design provides a clear observation area for your intended purposes. All accessories, including an optional high flow water pump or a Finnex P-2000 air pump and airline for the basic models are included to get the system of your choice up and running right out of the box.
The box may be used as a quarantine area for sick or fish needing a quite zone to re-coupe. The lower flow gives fish a stable environment without giving them much stress. Ideal for both fresh and saltwater aquariums, some may use it to selective breed their most prized shrimps and fish. Or, simply use it to house a betta, without having a bulky housing taking up space inside your aquarium. Remove the removable baffles for additional space and attach any clip light to have your refugium thriving. The multifunctional box can be used as a refugium filtration system where pods and cheato can further cycle one's aquarium as well as lowering nitrates.
The Shiruba PH-101 Nano Pump: For those needing an increased flow throughout the box for refugium purposes, this pump flows 40 gph. Also included with the pump is a unique adapter that allows easy attachment to the Finnex Breeder Box and other similar breeder boxes. In addition, this pump also allows for a controlled flow, meaning you can adjust the needed flow accordingly.
The FINNEX ULTRA SLIM LEDs: Add a sleek designed light to illuminate your Finnex Breeder Box. Capable of supporting all aquatic growth when using as a refugium light. Light is also equipped with moonlights for your night time viewing pleasures.
