AST FILTER MEDIA
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.
Standard Filter Media provides:
+ Excellent Biological Filtration
+ Superior Solids Removal
+ Low Head Loss
+ Superior Solids Capture
+ Low Water Loss (1-10% that of sand filters)
+ Never Needs Replacing
Enhanced Media provides all of the same great benefits plus:
+ Robust Biofiltration (50% boost over Standard Media)
+ Protects the Biofilm from Frequent Backwashing
Enhanced media is shaped to protect the bio-film from abrasive backwashing. This makes it suitable for systems requiring frequent backwashing that have high biofiltration requirements, eliminating the need for moving bed bioreactors in many applications.
