Biological and Mechanical Pond Filters that create clean, fresh, and healthy ponds and ecosystems.

Whatever you pond needs may be, we have pond filters for you
There are two primary types of pond filters: Mechanical and Biological. Mechanical pond filters are for capturing and removing physical debris from the pond. Biological pond filters are for processing and removing dissolved chemical compounds from the pond.
Mechanical Pond Filters consist of pond skimmers, and/or pond sieve. A pond skimmer utilizes the suction power of a pump to pull surface water and floating debris into its internal filtering mechanism. A pond sieve utilizes a combination of pump suction and gravity to pull submerged debris from a drain at the bottom of the pond into its own filtering mechanism.
Biological Pond Filters fall into many categories, but the two most popular are waterfall filters and bead filters. First of all, we need to discuss what a biological filter, or biofilter for short is. In simple terms, a biofilter is a device that contains media with specific surface area (SSA) for growing beneficial bacteria. The bacteria use chemical compounds such as the ammonia released from fish as their food source.
Fish release ammonia into the water through respiration and “going to the bathroom”. The bacteria living on the media inside the biofilter feed upon the ammonia as the water is passed through the media. Other compounds such as phosphorus and other dissolved chemicals are also food sources for certain types of bacteria.
Waterfall Filters are biofilters that when installed, are virtually invisible. They become the starting point of a waterfall. There are many brands of waterfall filters available, but patented Hydro Vortex™ waterfall filters are easier to clean.
Water enters each model of Hydro Vortex™ filter at point that is perpendicular to the radius of the round filter body. Water whirls in a vortex to spin heavier particulates to the bottom of the vortex for removal via a drain. Water then moves upward through the media chamber containing Hydro FilterSilk™ biomedia. The biomedia has been seeded with HydroClear™ Nitrification Cycle bacteria. Water passes through the biomedia where the bacteria feed upon, and thereby remove ammonia and other dissolved organics from the water. The water exits to the top of the filter and returns to the pond by water of a waterfall.
Bead Filters are the most common type of koi pond filter. HydroBead™ Vortex filters features a round tank. Like the Hydro Vortex™ waterfall filters mentioned above, the water enters the tank through an inlet that forces the water to whirl in a vortex. Water whirls in the vortex to spin heavier particulates to the bottom of the vortex for removal via a drain. Water then moves upward through the media chamber containing HydroFoam™ Bead biomedia. The biomedia has been seeded with HydroClear™ Nitrification Cycle bacteria. Water passes through the biomedia where the bacteria feed upon, and thereby remove ammonia and other dissolved organics from the water. The water exits the tank through an outlet lateral to pipe. The pipe returns the water back to the pond.
