Reduce Nutrients in Your Pond
The health and clarity of your pond can be improved with a simple year-round filtration system that will reduce phosphorus, nitrate, ammonia by means of competitive exclusion.
How the Country Pond Filter Works
The Country Pond Filter supports an active biofilm composed of unicellular algae, heterotrophic and autotrophic bacteria. The biofilm will colonize on the gravel media and effectively reduces nutrients as the volume of pond water is retained for a short period of time.
Pond owners and pond contractors alike will find this system easy to install and fully complementary with other biological treatments when dealing with duckweed, cyanobacteria, or filamentous algae blooms.

What Are the Benefits of Biological Pond Filtration?
- Cold water temperature reduces the growth of beneficial bacteria and phyto filters populated with aquatic plants. Algae biofilms remain viable and productive.
- Installation is possible with minimal site preparation.
- Filters can be upsized to one acre for large installations
- Only 2.5cm of pea stone gravel is needed to cover the liner and support the biofilm
- Monthly service is generally not required but can be provided for the customer during scheduled pond site visits
- The submersible pump used to supply water to the filter is very energy efficient, 120 volts, 80 watts
- Flowing water does not freeze. Tested below Zero Fahrenheit.
How Does the Country Pond Filter Work?
The Country Pond Filter uses a photo bio-reactor system and gravel media to eliminate excess nutrients like phosphorus and ammonia. By continuously filtering water without freezing, it reduces the nutrients that support cyanobacteria (blue-green algae) blooms without requiring harsh chemical treatments.
The Country Pond Filter is a biological system that helps reduce nutrient levels in your pond. Nutrients that impact water quality may enter your pond from external sources, such as fertilizer runoff, and from organic materials on the bottom being resuspended or digested by microbial action.
The size of a filter is determined by calculating the surface acreage of the pond and measuring the amount of nutrients that are in the water. Filters up to one acre in size can be constructed with one piece of liner material. The setup can be done by most people
