Burtons Submersible UV Clarifiers

High output ultraviolet clarifiers designed for Burtons drum filters and professional pond filtration systems.

Burtons Submersible UV clarifiers are designed to help pond owners maintain clear and healthy water by controlling green water algae and harmful microorganisms. Installed directly inside the filtration system, these UV units expose pond water to powerful ultraviolet light as it passes through the filter.

Ultraviolet light disrupts the reproduction of free floating algae cells, preventing them from multiplying. As a result, green water begins to clear and the overall quality of the pond water improves.

The Burtons Submersible UV range includes units from 10 watt up to 80 watt, making them suitable for a wide variety of pond sizes. Smaller units are ideal for ornamental ponds or lightly stocked fish ponds, while larger units provide the stronger UV output required for larger ponds and koi pond filtration systems.

Each UV unit is supplied complete with a UV lamp, quartz sleeve and electronic ballast, ensuring reliable performance and straightforward installation.

Designed for Drum Filter Installation

Unlike traditional inline UV clarifiers that are installed within pipework, Burtons Submersible UV units are designed to sit directly inside drum filters and filtration chambers.

This allows pond water to receive ultraviolet treatment at one of the most effective stages of the filtration process. As the water passes through the drum filter, it is exposed to the UV lamp which helps control algae and improve water clarity.

Another important advantage is that ultraviolet light can help reduce organic biofilm forming on the drum mesh. Over time this biofilm can restrict water flow through the screen which causes the drum filter to perform cleaning cycles more frequently.

By reducing this build up, the UV unit helps keep the drum mesh cleaner for longer. Water can therefore pass through the filter more easily and the drum filter can operate more efficiently.

Standard UV and Amalgam UV Options

Burtons offer both Standard UV and Amalgam UV versions within the submersible UV range.

Standard UV units provide dependable algae control and are suitable for most garden ponds and koi ponds. These lamps typically offer a bulb life of up to 10,000 hours when operated under normal conditions.

For larger ponds or filtration systems that require stronger UV output, Burtons Submersible Amalgam UV units provide a higher performance option. These lamps produce greater ultraviolet intensity and have an extended bulb life of up to 13,000 hours.

Amalgam UV technology also allows the lamp to operate efficiently across a wider temperature range while maintaining stable UV output.

Choosing the Correct UV Size

Selecting the correct UV unit depends on several factors including pond volume, fish stocking levels and the filtration system being used.

Smaller ornamental ponds may only require a 10 watt or 20 watt unit, while larger ponds or koi ponds often benefit from the higher output provided by the 30 watt, 40 watt or 80 watt models.

Choosing the correct UV size ensures effective algae control while helping maintain stable water quality.

Which Burtons UV Fits Each Drum Filter

Burtons Submersible UV clarifiers are designed to integrate directly with Burtons drum filters and combi filtration systems. Selecting the correct UV unit for your filter ensures the best algae control and filtration performance.

Typical recommendations include:

Burtons Submersible UV Clarifiers – Frequently Asked Questions

Below are some of the most common questions about Burtons Submersible UV clarifiers. These answers explain how pond UV lights work, why they are important for drum filter systems and how to choose the correct UV unit for your pond.

What are Burtons Submersible UV clarifiers?

Burtons Submersible UV clarifiers are ultraviolet light units designed to be installed directly inside pond filtration systems such as drum filters and combi filters. They emit UV light which disrupts algae cells and prevents them from multiplying.

By doing this, the UV clarifier helps eliminate green water and maintain clear pond water. They are commonly used in koi ponds, ornamental ponds and larger filtration systems where reliable algae control is required.

Why do ponds need a UV clarifier?

Green water algae is one of the most common problems pond owners experience. These microscopic algae cells multiply rapidly when nutrients and sunlight are present.

A pond UV clarifier prevents this problem by exposing the water to ultraviolet light. The UV radiation damages the algae cells so they cannot reproduce.

Once the algae cells are neutralised they can be removed by the filtration system, allowing the pond water to become clear again.

What is the difference between standard UV and amalgam UV?

Standard UV clarifiers use traditional ultraviolet lamps and typically offer a lamp life of around 10,000 hours.

Amalgam UV clarifiers use a more advanced lamp technology that produces a higher ultraviolet output. They also have a longer lamp life, often lasting up to 13,000 hours.

Because of their stronger UV intensity and longer lifespan, amalgam UV units are often preferred for larger ponds or heavily stocked koi ponds.

Why install a UV inside a drum filter?

Installing a UV clarifier inside a drum filter allows pond water to receive ultraviolet treatment at one of the most effective stages of the filtration process.

As water passes through the drum filter it flows directly past the UV lamp. This allows algae cells to be treated immediately before they pass through the rest of the filtration system.

Another benefit is that ultraviolet light can help reduce organic biofilm building up on the drum mesh. By limiting this growth the drum screen stays cleaner for longer which can reduce the number of cleaning cycles required.

Which Burtons UV fits each drum filter?

Burtons Submersible UV clarifiers are commonly matched with specific drum filter models.

Typical pairings include:

BD150 Combi
10 watt UV

BD300 and BD300 Cube
20 watt UV

BD500
30 watt UV

BD700 and BD1000
40 watt or 80 watt UV depending on pond size and stocking levels

For installation inside some drum filters including the BD300, BD300 Combi, BD500 and BD700 a stainless steel UV mounting fitting is required.

What size UV do I need for my pond?

Choosing the correct UV size depends on several factors including pond volume, fish stocking levels and the type of filtration system installed.

As a general guide:

Small ornamental ponds may require a 10 watt or 20 watt unit.
Medium sized ponds may require a 30 watt unit.
Large ponds and koi ponds often require a 40 watt or 80 watt UV unit.

If you are unsure which UV size is best for your pond, it is always best to seek advice before purchasing.

Do UV clarifiers remove green water completely?

Yes, a correctly sized UV clarifier will usually clear green water within a few days to a week. The UV light prevents algae cells from reproducing, allowing the filtration system to remove them from the pond.

However, the speed of results can depend on pond size, sunlight levels and how powerful the UV unit is compared with the pond volume.

How quickly will a UV clarifier clear green water?

In many cases green water begins to improve within 24 to 72 hours after installing a UV clarifier. Most ponds will become clear within about one week once the algae cells have been neutralised and removed by the filtration system.

Can a UV clarifier improve pond water quality?

Yes. Although a UV clarifier does not remove waste or nutrients directly, it plays an important role in maintaining clear water.

By controlling microscopic algae, the UV clarifier allows the filtration system to work more efficiently and helps maintain a healthier pond environment.

Can UV clarifiers help reduce drum filter cleaning cycles?

Yes. When installed inside a drum filter, ultraviolet light can help reduce organic biofilm forming on the drum mesh.

This biofilm can restrict water flow and cause the drum to trigger cleaning cycles more frequently. By reducing organic build up, the UV unit can help keep the mesh cleaner and improve filtration efficiency.

Are submersible UV clarifiers better than inline UV units?

Both types of UV clarifier can be effective, but submersible UV units offer several advantages when used with drum filters.

Because they sit directly inside the filtration chamber, the water receives ultraviolet treatment immediately as it passes through the filter. This can improve algae control and help reduce biofilm build up on drum screens.

What does a quartz sleeve do in a UV clarifier?

The quartz sleeve surrounds the UV lamp and protects it from direct contact with water.

Quartz glass allows ultraviolet light to pass through very efficiently, which ensures the UV radiation can treat the pond water effectively while protecting the lamp from damage.

Do UV clarifiers kill blanketweed?

UV clarifiers are designed to control free floating algae that causes green water. Blanketweed and string algae are attached algae which grow on pond surfaces.

While UV clarifiers will not directly remove blanketweed, maintaining clear water and balanced filtration can help reduce conditions that allow blanketweed to thrive.

Do UV clarifiers remove bacteria from pond water?

UV clarifiers can reduce harmful bacteria and microorganisms present in the water by damaging their DNA and preventing them from reproducing.

However, they do not replace biological filtration. A good pond filtration system is still required to break down fish waste and maintain stable water quality.

Are UV clarifiers safe for fish and plants?

Yes. UV clarifiers are completely safe for fish, pond plants and wildlife when installed correctly.

The ultraviolet light remains contained within the filtration system and does not affect fish or plants directly. Instead it treats the water as it flows through the filter.

Can UV clarifiers be used in koi ponds?

Yes. UV clarifiers are widely used in koi ponds because they help maintain clear water while reducing algae growth.

Clear water is particularly important in koi ponds as it allows pond keepers to observe fish health and behaviour more easily.

Can a UV clarifier be installed in any filter system?

Most UV clarifiers can be installed in a wide range of filtration systems, although the installation method may vary.

Burtons Submersible UV units are specifically designed for installation inside filtration chambers such as drum filters and combi filters.

How often should a UV clarifier be cleaned?

Over time a thin film can form on the quartz sleeve that surrounds the UV lamp. This film can reduce the amount of ultraviolet light reaching the water.

Cleaning the quartz sleeve periodically helps maintain the efficiency of the UV unit. Many pond owners clean their UV clarifier when they perform routine filter maintenance.

How long do Burtons UV lamps last?

Standard UV lamps typically last up to 10,000 hours.

Amalgam UV lamps have a longer lifespan and can last up to 13,000 hours under normal operating conditions.

Even if the lamp is still glowing after this time it will gradually lose UV output, so replacing the lamp periodically helps maintain effective algae control.

Can I run a UV clarifier all year?

Yes, many pond owners run their UV clarifier continuously throughout the year. However, UV clarifiers are most important during the warmer months when algae growth is strongest.

Running the UV through spring, summer and early autumn usually provides the best results for maintaining clear water.

Do UV clarifiers use a lot of electricity?

No. UV clarifiers are generally very energy efficient. The power consumption depends on the wattage of the UV lamp, but even larger UV units typically use relatively little electricity compared with pumps and other filtration equipment.

Do Burtons UV clarifiers come complete with everything needed?

Yes. Burtons Submersible UV units are supplied as a complete kit including the UV lamp, quartz sleeve and electronic ballast.

Some drum filters may require a stainless steel mounting fitting to install the UV inside the filter housing.
