Bio-Pin Ball, Large 2500 count

Description

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-Pin Balls help product turbulence, aiding in the gas-exchange process. The void space between Bio-Pins is ideal for the movement of gasses like oxygen and enhances contact with nitrifing bacteria living on the media surface.

Large Bio-Balls: One Bio-Pin ball has 150 Bio-Pins (drip points). There are 74 balls per gallon. One cu.ft. of media has approximately 130 sq. ft. of surface area. The suggested usage is one gallon of Bio-Pin Balls per 20 gallons for salt water and one gal. per 35 gallons of freshwater. Outside Diameter 1.60"
