NishikigoiUV – High-Output UV Sterilizers for Koi Ponds

Keep your koi pond clear, clean, and easy to enjoy with NishikigoiUV. Designed specifically for serious koi keepers and professional pond filtration systems, NishikigoiUV combines high-output amalgam UV technology, 316 stainless-steel construction, and dependable electronic controls for powerful, long-term performance.

Clear water is about more than appearance. Improved water clarity makes it easier to appreciate the color, pattern, skin quality, and condition of your koi while helping maintain a cleaner pond environment.

Powerful UV Performance for Koi Ponds

NishikigoiUV systems use high-output amalgam ultraviolet lamps to provide strong and consistent UV exposure as pond water passes through the stainless-steel chamber.

The UV light targets free-floating algae responsible for green water, allowing the affected particles to be removed more effectively by the pond’s mechanical filtration system.

The result is improved water clarity and a clearer view of your koi.

Amalgam lamp technology also provides excellent UV output for the higher flow rates commonly used in modern koi pond filtration systems.

Marine-Grade 316 Stainless-Steel Construction

The NishikigoiUV chamber is manufactured from durable marine-grade 316 stainless steel, providing excellent corrosion resistance, structural strength, and long service life.

Unlike many plastic UV housings, the heavy-duty stainless-steel vessel is designed for demanding pond installations and professional filtration environments.

The polished interior surface also helps reflect UV energy within the chamber, allowing efficient use of the lamp’s ultraviolet output.

The stainless-steel vessel is backed by a lifetime warranty, excluding rubber components.

Long-Life Amalgam UV Lamps

NishikigoiUV amalgam lamps are rated for approximately 13,000 operating hours, providing longer service life than many conventional UV lamps rated around 9,000 hours.

Benefits include:

• Longer intervals between lamp replacement
• Reduced maintenance
• Consistent UV performance
• Excellent reliability during the pond season
• Lower long-term operating maintenance

Depending on the model, NishikigoiUV systems are equipped with one to six UV lamps.

On multi-lamp models, each lamp utilizes an individual ballast, allowing the remaining lamps to continue operating if one lamp or ballast requires service.

Convenient Monitoring & Control

Most NishikigoiUV models include a separate weather-resistant stainless-steel control box designed to simplify system monitoring and maintenance.

Depending on the model, features include:

• Individual UV lamp operation indicators
• Hour meter for monitoring lamp operating time
• Individual electronic ballasts
• Detachable control box
• Weather-resistant stainless-steel enclosure

The built-in hour meter makes it easier to track lamp life and determine when UV lamps are approaching their recommended replacement interval.

Vertical or Horizontal Installation Options

NishikigoiUV systems are available in both vertical and horizontal orientations, giving pond owners and installers greater flexibility when designing or upgrading a filtration system.

The correct orientation depends on your available equipment-room space, plumbing layout, access for maintenance, and overall filtration design.

Important Ordering Note: When ordering through the Koi Enterprise website, please carefully double-check your selected model and orientation before completing your purchase. Vertical and horizontal models are different configurations, so make sure your selection matches your intended installation.

If you are unsure which version you need, contact Koi Enterprise before ordering and we can help confirm the proper configuration.

Heavy-Duty Schedule 80 Unions

NishikigoiUV systems include heavy-duty Schedule 80 unions for secure connection to your pond filtration plumbing.

The union design also makes removal and servicing of the UV chamber easier when routine maintenance or lamp replacement is required.

Available From 80 to 480 Watts

NishikigoiUV systems are available in a wide range of sizes to accommodate residential koi ponds, high-flow filtration systems, commercial installations, and heavily stocked ponds.

Available models range from approximately 80 watts to 480 watts.

Selecting the correct UV system depends on several factors, including:

• Pond volume
• Actual water flow rate
• Pond turnover rate
• Sun exposure
• Fish load
• Water clarity
• Filtration efficiency
• Plumbing configuration
• Desired UV contact time

UV sizing should never be based on pond gallons alone. Proper sizing according to actual system flow rate and application is critical for achieving the best performance.
