Optimal bio-filtration is achieved when the filter medium perfectly combines the two most critical criteria. First is an adequate water flow, second is a high surface area for bacteria to grow.

These strong mats hardly deteriorate at all over time and create an excellent environment for growing bacteria in your pond filter.
