Granular Activated Carbon

Description

Our Granular Activated Carbon (GAC) is a special grade bituminous carbon, liquid phase activated, made specifically for aquarium use.  It has a larger pore structure than typical bituminous carbons, making it more like lignite, but slightly harder and with less dust.  The larger particle size at 4x12 mesh, makes it an ideal carbon to be used in media reactors, mesh bags, or cartridges.  Produced entirely in the USA, it contains zero contaminants and will not leach phosphate into your water.
Fast acting, works quickly to eliminate cloudy water, colors and odors.
Made according to Food Chemicals Codex (FCC) Standards.
Laboratory grade granular activated carbon, optimum pore structure, made specifically for aquarium use.
Large granules are perfect for use in all filter types.
Instructions:
Dosage = 1 cup per 50 gallons of aquarium water
If using a fluidized media reactor: Fill with the desired amount of carbon and hold in place with filter pad. Rinse the carbon by placing the return line in a bucket or sink, and run until water is clear. Adjust flow rate to a slower flow rate and ensure carbon is not tumbling.
If using a media bag: Place the desired amount of carbon in the media bag and rinse until it runs clear. Do not grind it while rinsing. Place in high flow area of sump or tank.
