Savio Engineering
The Savio Livingponds Compact is a pressurized pond filter combining mechanical and biological filtration in a single unit. It uses a multi-stage filtration approach with foam pads and biological media to remove suspended solids and support nitrifying bacteria. It connects inline between the pump and the waterfall or return line and is suitable for ponds up to approximately 2000 gallons with moderate fish loads.
$150 - $300
Tetra Pond
The Tetra Pond ClearChoice BioFilter is a gravity-fed biological filter that pairs with Tetra Pond pumps in above-waterfall installations. It uses a thick biological mesh media pad that supports a large colony of nitrifying bacteria for ammonia and nitrite conversion. The gravity-fed design allows high flow rates without pump strain and the media pad lifts out for easy hosing during maintenance.
$80 - $160
Oase
The Oase FiltoClear is a German-engineered pressurized pond filter with an integrated UV clarifier and an automatic backwash system that cleans the foam media without disassembly. The integrated UV lamp reduces free-floating algae and suspended bacteria. FiltoClear models range from 3000 to 16000 gallon ratings and are a popular choice for koi pond keepers who want a self-maintaining filtration unit.
$200 - $600
Oase
The Oase BioSmart is a gravity flow-through pond filter designed for above-waterfall or waterfall-edge installation. It uses a series of foam pads in increasing density for mechanical and biological filtration, and includes a backwash handle for in-place cleaning without removing the media. The BioSmart is known for reliable performance and is one of the most widely recommended mid-range pond filters for koi ponds in the 2000 to 10000 gallon range.

Aqua Ultraviolet
Aqua Ultraviolet is a California-based manufacturer that has specialized in UV sterilization equipment for ponds and aquaculture since 1983. Their Advantage series UV sterilizers use a high-output UV lamp inside a quartz sleeve to kill free-floating algae, bacteria, and parasites. Models range from 8 watts for small ponds to 280 watts for large commercial installations. They are among the most respected UV brands in the koi pond industry.
$120 - $800
Sequence Pumps
Sequence Pumps manufactures high-flow, energy-efficient centrifugal pond pumps designed for large koi ponds and water features requiring continuous high-volume circulation. Their pumps are known for reliability, relatively low power consumption for their flow rate, and the ability to handle solids-laden water without clogging. The Sequence series is widely used in professional koi installations and by serious hobbyists with large pond volumes.
$300 - $900
Anjon Manufacturing
Anjon Manufacturing's Frog Filter is a biological waterfall filter designed for mid-size koi ponds. It sits at the top of the pond waterfall, receives water pumped from the bottom drain or pump, and returns filtered water as a waterfall. The design uses biological filtration media bags that are easy to remove and rinse. The low-profile housing integrates naturally into rockwork-style waterfall designs.

The Max-Flo series uses a dirt and debris-resistant design with a pre-filter cage that reduces clogging in typical koi pond conditions.
$60 - $250
Hanna Instruments
The Hanna Instruments HI98107 pHep is a pocket-sized digital pH meter used by koi keepers and pond professionals for accurate pond water pH measurement. It provides results in 0.1 pH unit increments, is calibrated with the included buffer solution, and replaces the inaccurate color-comparison pH test kits common in pond care. The slim probe design works well for sampling directly from a pond edge or sump.
$25 - $45
API (Aquarium Pharmaceuticals)
The API Pond Master Test Kit tests for the four primary water quality parameters in koi ponds: pH, ammonia, nitrite, and phosphate using liquid reagents that give results by comparing water sample color to a reference card. It is the most widely used water test kit for pond keepers due to its availability, low cost per test, and reasonable accuracy for routine monitoring. Each kit contains enough reagents for 500 to 700 tests total across all four parameters.
