Standard Bead Media performs biological and mechanical filtration and never needs replacing. These specially sized media are made of low density polyethylene, a plastic commonly used in food packaging. These beads float in the top of the filter, allowing water to pass through with minimal head loss, while trapping solids. The plastic media provides an attachment area for nitrifying bacteria to break down toxic fish wastes, ammonia and nitrite.
