Unlike a natural pond, most man-made garden ponds do not have a source of running water. Thus, excess waste and other materials are not removed. This is why backyard ponds need a filter. Here are the best pond filters for both small and large ponds:
TetraPond Submersible Pond Filter
The TetraPond Submersible Pond Filter is capable of filtering waste materials from ponds up to 500 gallons. It’s an inexpensive yet functional garden pond filter that keeps the pond water clear, clean, and healthy.
Pond Boss Filter Kit with Pump
The Pond Boss Filter Kit comes with its own pump. It’s affordable, high-performance, and eco-friendly.
Aquagarden 5-in-1 Filtration System
For a more all-round solution, the Aquagarden 5-in-1 filtration system offers an instant solution for a clean and healthy pond: it comes with an efficient pump and filtration package for ponds up to 200 gallons.
It features a built-in 5 watts UV clarifier light that prevents green water and algae. It also has both a mechanical and biological filtration to keep your pond water clean and healthy.
OASE BioSmart 5000 Pond Filter
The OASE BioSmart 5000 Pond Filter uses both a mechanical and biological filtration system to keep pond water clear, clean, and healthy. It works best with ponds of up to 5,000 gallons that’s moderately stocked with fish.
It has a built-in foam pad cleaning mechanism and an alert system that lets you know when its time to clean the foam pads. It works perfectly with the TetraPond Pond Tubing connector and OASE AquaMax Eco Classic 1900 Pond and Waterfall Pump (manufacturer recommended).
TetraPond Bio-Active Pressure Filter with UV Clarifier
The TetraPond Bio-Active Pressure Filter with UV Clarifier is available in three sizes: 1,500, 2,500 and 4,000-gallon ponds. It features a backflush feature and it does not use foam pads.
It has both a mechanical and biological filtration system to help maintain clean and healthy pond water. The backflushing valve allows for fast cleaning.
There are also bio-activators that provide a large surface area and unrestricted water flow for improved cleaning. And, the integrated UV Clarifier helps control suspended algae.
