Filtration Systems for Ponds & Water Gardens

Selecting a Filter System

All ponds with fish will benefit from having a biological filter system installed. Filters generally have a maximum and minimum flow rate requirement. Goldfish ponds do fine when pumping the entire volume of the pond once every two hours and Koi ponds do better when turning the pond volume over once each hour. Greater flow is fine as long as it does not exceed your filter requirements. The following recommendations will work well for most ponds. When choosing a system for a large fish population or a pond for Koi you may want to look at the next size up. Also to ensure clear water year-round an ultraviolet sterilizer is highly recommended.

Filter options for Ponds up to 500 gallons using a submersible pump.

  1. If you want an all in one system that provides a fountain for the water return the Lifegard All-In-One is an excellent choice. This filter includes the pump.
  2. This option uses your submersible pump inside the Matala Pump Defender and run the plumbing from the pond to an Atlantic BF1000 FilterFalls, the PondMax PF1200 (with or without the UV option), or the Ultima II 1000 filter.
  3. To get the pump and plumbing out of the pond, improve the filtration, and reduce the amount of maintenance install a skimmer instead of using the Matala Pump Defender. This will be in addition to the filter options above.

Filter options for Ponds up to 3600 gallons.

  1. When using a submersible pump an option is to use the Matala Pump Defender or a solids handling pump to move the water to an Atlantic BF2600 filter or an Ultima II 4000 Filter.
  2. To get the plumbing out of the pond thereby improving appearance, increasing filtration, and decreasing maintenance install a skimmer instead of using the Matala Pump Defender.

  2. To get the plumbing out of the pond thereby improving appearance, increasing filtration, and decreasing maintenance install a skimmer instead of using the Matala Pump Defender.
