Matala Bio-Cubes | Pond & Aquarium Filter Media | 2 Sizes

Matala Bio-Cubes are ultra-high surface area filter media for ponds, water gardens or aquariums. Various sizes and densities, these cubes are cut from Matala fish-safe aquatic filter media, one of the leading brands of pond filter media. Save the time and effort of cutting filter mat to the specific size of your waterfall tank or biofilter by using these cubes!

Much lighter weight (about 2 lbs. per cu. ft.) than lava rock (over 50 lbs. per cu. ft.), these bio-cubes are also much more effective for biological filtration! The increased Bio-Cubes surface area allows good bacteria more areas to colonize, grow and eventually convert toxic ammonia and nitrites to harmless nitrates. This helps improve water quality for fish and other aquatic life. Another benefit is that these cubes are easy to clean - just rinse them off with water from a garden hose.

These filter cubes are a great upgrade for any brand of waterfall or biofilter tank, including Aquascape, Atlantic, EasyPro and Savio. Resistant to clogging, they provide years of effective, worry-free filtration with very little maintenance.

Each cu. ft. of cubes covers about 525 sq. ft. of surface area, much more than lava rock, bio-balls or ribbon materials. These bio-cubes allow your pond filter to maintain greater levels of beneficial bacteria for clearer water and a better ability to handle a larger fish load as your pond matures.

A free mesh bag ($6.99 value) is included to hold the bio-cubes.

Please Note: Bag color may vary. Ships compressed to reduce costs.
