Best Biological Pond Filters

The best biological pond filters use bacteria to break down and decompose pond waste into less harmful compounds.  These compounds then will be used by aquatic plants as potential fertilizers, just as compost is used to help gardens grow.

Water enters these types of filters through the bottom of the biological filter and then flows through and over the spillway creating the start of the waterfall.  The waterfall creates aeration for the pond, assisting in the circulation and health of the water.

Dissolved oxygen is imperative in any pond ecosystem to ensure the health of the aquatic plants and fish.  Not to mention, the health of the aerobic bacteria.
