Danner Submersible Ultraviolet Clarifier | 10 Watt

Continuous UV-C Water Clarification for Reservoirs, 10 W

Algae blooms and waterborne pathogens spread quickly through a shared nutrient reservoir, clogging lines and stressing roots before a grower notices cloudy water. The Danner Submersible Ultraviolet Clarifier exposes circulating water to germicidal UV-C light as it passes through the unit, breaking down algae cells and inactivating many waterborne microorganisms without adding chemicals to the reservoir.

At 10 watts, this clarifier suits smaller recirculating reservoirs and water features where a compact, low-wattage unit is enough to keep water clear between full changeouts. It runs submersible in the reservoir or inline with existing plumbing.

Key Features & Benefits

• 10-watt UV-C bulb — exposes circulating water to germicidal UV-C light that breaks down algae cells and inactivates many waterborne microorganisms.
• Submersible or inline installation — fits directly into a reservoir or plumbs into an existing recirculating line without major system changes.
• Chemical-free treatment — clarifies water through UV-C exposure alone, without adding algaecides or other chemical additives to the reservoir.
• Compact 10 W draw — sized for smaller reservoirs and water features rather than large commercial volumes.
• Continuous operation — treats water as it recirculates, reducing the need for manual algae scraping and cleaning.

Who Should Use The Danner Submersible Ultraviolet Clarifier

Growers running smaller recirculating reservoirs or water features who want to control algae growth without adding chemical treatments to the nutrient solution.

About Danner Ultraviolet Clarifiers

Danner manufactures submersible pumps and water treatment equipment for pond, aquatic, and recirculating water applications, applying UV-C clarification technology developed for pond maintenance to hydroponic reservoir use.

Frequently Asked Questions

What does a UV clarifier actually do to reservoir water?

It exposes water to germicidal UV-C light as it passes through the unit, which breaks down algae cell structure and inactivates many waterborne bacteria and pathogens without adding any chemicals to the solution.

Does UV treatment harm beneficial microbes or root inoculants?

Yes, UV-C light is non-selective and will also affect beneficial microbes, so growers dosing biological inoculants typically add them after the UV stage or run the clarifier on a bypass during dosing.

How is a 10-watt clarifier sized to a reservoir?

Wattage is matched to reservoir volume and flow rate — a 10-watt unit suits smaller recirculating reservoirs and water features rather than large commercial-volume systems.

How often does the UV bulb need replacement?

UV-C output degrades gradually with use, so most growers replace the bulb roughly every six to twelve months to maintain effective clarification even though the bulb may still light up.

Can this unit run continuously?

Yes, it's designed for continuous operation as part of a recirculating system, which is how it keeps ongoing algae growth in check rather than treating water in a single pass.
