- Provides biological filtration and aeration to aquarium
- Includes airline diffusers, carbon cartridges, Discard-A-Stone and fish-saver feature
- For use in fresh and saltwater aquariums
Placed on the bottom surface of the aquarium, the filter plates utilize the gravel bed as a source of surface area for bio-filtration and provide oxygen by recirculating the water down through the media and up through the uplift tubes.
The advanced design allows separate plate installation and features optional flow-thru setup, which can be used with a powerhead. Adjustable 1" uplift tubes provide superior water circulation. The filter is made of special, premium quality plastic which resists splitting and cracking.
Note: Must be attached to an air pump or powerhead (sold separately).
