A filter with dual chamber mechanisms that provides both biological and mechanical filtration, this filter is an absolutely fantastic choice. Its multifaceted approach to helping filter out sediments while supporting good aerobic bacteria colonization plays a key role in what makes this filter so special and effective.
Viable for up to 1600 gallons with fish in the version we linked here and other higher and lower volumes in other models, this filter is a good starting point for beginners and a solid asset for more experienced koi keepers. If you are looking for something cut and dry that gets the job done, you cannot go wrong with this Grech filter.
An excellent mid-range option with a ton of features despite its incredibly low price point, the OASE BioSmart filter works for ponds up to 10,000 gallons with no fish load and a slightly lower, varying gallon limit based on the fish density of the pond.
Providing both mechanical sieve filtration, as in the water is pushed through a metal sieve which removes physical debris, and biological filtration via a second media, this well rounded model is fantastic for ponds where crystal clear water is vital to the aesthetic. Plus the media is kept in separate, distinct zones, which means the growth of beneficial bacteria will go undisrupted by debris and sediment!
Fantastic for both aqua gardens and koi ponds alike, this versatile little filter packs a powerful punch despite its rather petite size.
Handling up to 1000 or 3100 gallons of water, this filter employs a unique two color media set up to help remove sediments. The blue foam media removes coarse sediment and physically large debris while the second yellow media works to take out finer pieces that cannot be as easily caught.
It provides amazingly clear water and a place for bacteria to grow. For those with smaller ponds, this model from PondH2o is an option you truly cannot go wrong with.
Suiting up to 21,000 gallons at a time, this pump is fantastic for a wide range of pond styles. Though technically designed for use with a swimming pool, sand filters are an inexpensive and low maintenance way to keep your pond clear if you have a good regulation of beneficial bacteria and a good water quality.
In general, this is a solid no frills option that will provide cleansing and very clear water in a low fish load pond or one with a good waste management plan. Rx Clear truly created something amazing with this product.
Despite being rather expensive, the GC Tek Aquabead filter is a wonderful choice that deserves considering if you are looking to invest in something that will do the job to an almost unbelievable degree.
This filter uses bio ball media to promote bacterial growth and generally clean the pond, plus the brand’s own one of a kind self-cleaning mode called Aquaswirl Internal Vortex mode, which pushes all of the sediment to the center of the tank and declumps the media without disrupting the bacterial growth.
Plus, the lifetime warranty is a pretty fantastic selling point, too!
