Oase Filtral UVC Premium

Oase Filtral UVC Premium

All In One Submersible Pond Filter with Built In UV

The Oase Filtral UVC Premium range provides a compact, fully integrated filtration solution for small garden ponds, wildlife ponds and goldfish ponds. Designed to sit discreetly on the pond floor, each unit combines pump, mechanical filtration, biological media and ultraviolet clarification within one submersible housing.

Because the entire system is contained within a single body, installation is straightforward. There is no requirement for external pipework, separate UV clarifiers or additional filter chambers. As a result, the Filtral UVC Premium series is ideal for smaller ponds where space saving, simplicity and ease of maintenance are important.

These filters are suitable for wildlife ponds up to 9,000 litres or goldfish ponds up to 4,500 litres, depending on model and stocking levels.

Integrated Mechanical and Biological Filtration

The Filtral UVC Premium operates as a complete underwater filtration system.

Firstly, the integrated pump draws water through a perforated intake lid. This protects the internal components while maintaining consistent water circulation.

Water then passes through multiple filtration stages:

• Coarse blue filter foams trap larger debris
• Fine red filter foams capture suspended particles
• Hollow ceramic media increases surface area for beneficial bacteria
• Moving biological elements support ammonia and nitrite breakdown

Together, these stages deliver effective mechanical waste removal and stable biological filtration within a compact footprint.

Built In UV Clarifier for Green Water Control

After mechanical and biological treatment, water passes through the integrated ultraviolet clarifier before returning to the pond.

With UV outputs ranging from 5 watts to 13 watts depending on model, the Filtral UVC Premium helps prevent green water caused by single celled algae. This improves clarity while supporting a balanced aquatic environment.

Because the UV is built into the unit, there is no need for a separate external clarifier.

Quiet, Discreet and Easy to Maintain

The fully submersible design allows the filter to operate quietly beneath the water surface. There are no visible filter boxes or exposed pipework around the pond edge.

Maintenance is simple. Filter foams are easily accessible for routine cleaning, and the integrated layout reduces the number of components requiring attention.

This makes the Filtral UVC Premium range particularly well suited to:

• Wildlife ponds
• Preformed ponds
• Small ornamental ponds
• Goldfish ponds
• Decorative water features

Oase Filtral UVC Premium All in One Filter – Frequently Asked Questions

The Oase Filtral UVC Premium range is designed as a compact, fully integrated pond filtration system for small garden ponds, wildlife ponds and goldfish ponds. Below are some of the most common questions we receive about installation, performance, maintenance and suitability.

What is the Oase Filtral UVC Premium all in one filter?

The Oase Filtral UVC Premium is a fully submersible pond filter unit that combines mechanical filtration, biological filtration, an integrated pond pump and a built in ultraviolet clarifier within a single compact housing.

Because everything is contained in one unit, it sits directly on the pond floor and does not require external pipework or a separate filter box. This makes it ideal for smaller ornamental ponds, preformed ponds and wildlife features where space and aesthetics are important.

The range includes several models suitable for ponds up to 9,000 litres for wildlife ponds, or approximately 4,500 litres when stocked with goldfish.

How does the Filtral UVC Premium filter work?

The Filtral draws water in through its perforated outer housing. Firstly, large debris is trapped by the coarse blue filter foams. Secondly, finer waste particles are captured by the finer red filter foams.

After mechanical filtration, water passes through ceramic media and biological elements that provide surface area for beneficial bacteria. These bacteria break down dissolved ammonia and nitrite into less harmful nitrate.

Finally, the water passes through the integrated UVC clarifier before returning to the pond. The ultraviolet light neutralises single celled algae, preventing green water and improving clarity.

Because all stages operate together inside one unit, the system provides complete small pond filtration in a compact format.

What size pond is the Filtral UVC Premium suitable for?

Suitability depends on fish stocking levels.

For wildlife ponds with no fish, the larger models in the range can handle ponds up to 9,000 litres. However, for goldfish ponds, the recommended capacity is reduced to around 4,500 litres.

If the pond contains koi, heavy fish loads or high feeding regimes, a larger external filtration system such as a pressure filter or moving bed filter would be more appropriate.

If you are unsure which model suits your pond, it is always best to ask before purchasing.

Does the built in UVC really prevent green water?

Yes, the integrated ultraviolet clarifier is designed specifically to combat green water algae.

As pond water passes the UV lamp, microscopic algae cells are disrupted. Consequently, they clump together and are then captured by the filter foams.

The UVC wattage varies between models, ranging from 5 watts to 13 watts depending on unit size. Correct sizing and regular bulb replacement are essential for consistent performance.

Is the Filtral UVC Premium easy to maintain?

Maintenance is straightforward, which makes this unit popular with first time pond owners.

The filter foams can be removed and rinsed in pond water. In addition, the integrated cleaning indicator on certain models helps show when maintenance is required.

However, like all compact all in one pond filters, regular cleaning is important to maintain flow rate and prevent performance drop off. Heavily stocked ponds will require more frequent maintenance.

Can the Filtral UVC Premium power a fountain or waterfall?

Yes. The unit includes an adjustable outlet and fountain attachment set on most models. This allows you to create decorative water displays while simultaneously filtering the pond.

Additionally, the flow can be adjusted to suit pond depth and desired fountain height. Some models also allow diversion to a small waterfall or feature outlet.

This makes the Filtral UVC Premium suitable for both functional filtration and visual enhancement.

Is the Filtral suitable for koi ponds?

The Filtral range is not designed for koi ponds.

Although it can technically circulate water, koi produce significantly more waste than goldfish or wildlife ponds. Therefore, a larger external filter with greater biological capacity is recommended for koi installations.

For koi systems, we would normally suggest drum filters, pressure filters, or Nexus filtration systems depending on pond size.

Does the filter need to be removed in winter?

The Filtral UVC Premium can remain submerged during winter as long as the pond does not freeze solid.

However, if removed, it should be stored in a frost free location. Always ensure the UVC unit is switched off before servicing, and replace UV bulbs annually to maintain algae control.

Who is the Filtral UVC Premium best suited for?

This filter is ideal for:

• Small garden ponds
• Preformed pond shells
• Wildlife ponds
• Goldfish ponds
• Beginner pond installations
• Low fish load ornamental features

It is particularly suitable where a simple, discreet and compact filtration solution is required without installing external filter boxes or pipework.
