The PhosBan Reactor 550 is designed to push water upwards from the bottom and through the media. This forces an even distribution of water throughout the media and prevents channeling from occurring. The PhosBan 550 media reactor has a low profile and built-in hanging bracket making it ideal for "hang on the back" applications. The Phosban reactor can house your favorite filtration media.
The PhosBan 150 can be mounted under the aquarium or hung on the back of the aquarium. It comes with barb hose fittings for 1/2" tubing and a 1/2" barbed ball valve included for flow control. The Phosban 550 is compatible with any pump that uses 1/2" tubing and a flow rate between 100 and 250gph.
