There are two types of filtration systems;

Biological filtration– this type of filtration ensures the waster products in the pond plus the ammonia gas are turned into harmless materials. This is made possible by the tiny organisms and bacteria that thrive on the filter medium.

Mechanical filtration– mechanical filters sieve out solid waste, dirt and algae from the pond. They are relatively cheaper.

Other common types

Apart from using the pressurised pond filter, lets focus on the other types of filters that you can use.

Waterfall filters– they are usually located above the water level and have biological filter materials in the form of plastic bio balls, bio mesh or bio beads. They are best fit for small to medium sized ponds.

The in-pond pre-filters– suitable for small ponds. They are sponge filters attached to the intake of your pond. They are mostly placed in the middle of the pond. The filters provide mechanical filtration by aiding the removal of small particles present in the water.

UV Sterilizers– even though not a pond filter, they help in eliminating free-floating organic particulates including fungi, algae and other harmful bacteria from the water. They work by exposing the tiny organic materials to the high powered UV lights. They require a pump for continued water flow and are essential for ponds with fish.

Skimmers– includes a box mounted at the water level of the pond outside the liner. The skimmers main purpose is to remove large debris that might fall into your pond before they can sink to the bottom to decompose.

When deciding the best pond filter, you should consider the number and type of fish, the pond size and the space available to accommodate the filter.


After installing the filter in your pond, you must follow the manufacturers recommendations in regard to cleaning and replacing the filters and the filtration parts as well.

Most pond owners have the Ultra Violet Clarifier which kills green algae on water to keep the water clear.

Most of the bio filters have the UV clarifier.

An important point to note- not all ponds require a filtration system. Ponds with less fish or no fish at all do not require one.
