Additional Information

• State of the art filter media for use in fresh and salt water wet/dry systems. They may be connected together or randomly placed in the filter box.


• Bio-Balls help produce turbulence, aiding in the gas-exchange process. The void space between the Bio-Balls is ideal for the movement of gasses like oxygen and allows it to more-readily come in contact with nitrifying bacteria living on the media surface.


• The suggested usage is 1 gallon of Bio-Balls per 20 gallons for salt water or 35 gallons freshwater.
