Advanced Pond Filtration Systems

Oase is best known for its high quality pond filtration systems designed for both ornamental ponds and koi ponds.

ProfiClear Premium Compact Combi Drum Filters – The ProfiClear Premium Compact range combines automatic mechanical drum filtration with an integrated moving bed biological chamber using Hel-X media. These combi drum filters provide powerful waste removal and biological stability within a single streamlined unit. Ideal for koi ponds where space efficiency, performance and reduced maintenance are priorities.

ProfiClear Premium Modular Drum Filters – The ProfiClear Premium Modular system is designed for larger ponds and high stocking levels. It separates the mechanical drum module from the biological and pump chambers, allowing scalable filtration capacity and flexible installation. Modular systems are ideal for serious koi ponds requiring maximum performance and expansion potential.

FiltoClear Pressurised Filters – The Oase FiltoClear range combines mechanical and biological filtration with integrated UVC clarification in a compact pressurised unit. These filters are ideal for smaller koi ponds and ornamental ponds where discreet installation and simple maintenance are required.

BioTec ScreenMatic – An intelligent flow through filtration system featuring automatic screen cleaning to reduce maintenance and improve water clarity.

Hel-X Biological Filtration Technology

At the heart of many Oase ProfiClear systems is Hel-X biological filtration media. Designed to provide an exceptionally large protected surface area for beneficial bacteria, Hel-X supports the efficient conversion of ammonia and nitrite while remaining highly oxygenated and self cleaning.

Combined with moving bed filtration technology, Hel-X helps maintain excellent water quality while reducing maintenance requirements, making it a key component within many professional Oase filtration systems.

Oase – Frequently Asked Questions

Below you will find detailed answers to common questions about Oase pond filtration systems, drum filters, pumps, UVC clarifiers, lake aeration systems and professional water management equipment.

Who are Oase and where are they manufactured?

Oase is a German aquatic technology manufacturer founded in 1949. The company designs and engineers pond filtration systems, drum filters, pond pumps, UVC clarifiers, lake aerators and decorative fountain systems.

Oase products are developed with German engineering standards and undergo extensive testing for durability, efficiency and long term performance.

What makes Oase different from other pond equipment brands?

Oase focuses on complete system integration. Their pumps, drum filters, UVC clarifiers and control systems are designed to work together seamlessly.

Key advantages include:

  • German engineered reliability
  • Energy efficient pump technology
  • Advanced drum filtration systems
  • Integrated UVC clarification
  • Professional lake and fountain solutions
  • Long product lifespan

Oase is often chosen by professional pond builders and estate managers due to its build quality and system compatibility.

What is the difference between Oase ProfiClear Premium Compact and Modular drum filters?

ProfiClear Premium Compact systems are combi drum filters. They combine automatic mechanical drum filtration and moving bed biological filtration using Hel-X media in one integrated unit.

ProfiClear Premium Modular systems separate the mechanical drum, biological chambers and pump chambers into individual modules. This allows higher flow rates, greater scalability and easier expansion for larger or heavily stocked koi ponds.

Compact is ideal for space efficiency.
Modular is ideal for maximum performance and expandability.

Are Oase drum filters good for koi ponds?

Yes. Oase ProfiClear Premium drum filters are designed specifically for high performance koi pond filtration.

Automatic drum cleaning removes fine solids before they break down, helping maintain stable water parameters and improved clarity in heavily stocked ponds.

Correct sizing is essential for optimal results.

How does an Oase drum filter work?

Oase drum filters use a rotating stainless steel drum fitted with a fine mesh screen. As water passes through, solids are captured.

When the screen becomes blocked, an automatic cleaning cycle activates. Spray nozzles wash debris into a waste outlet, restoring flow without manual intervention.

This reduces maintenance and improves mechanical filtration efficiency.

What is Hel-X media used in Oase filters?

Hel-X is Oase’s biological filtration media used in moving bed chambers.

It provides a large protected surface area for beneficial bacteria to colonise. As the media moves, it remains clean and highly oxygenated, allowing effective ammonia and nitrite breakdown.

Which Oase filter is best for a small garden pond?

For smaller ornamental ponds, common options include:

  • Oase FiltoClear with integrated UVC
  • Oase BioTec ScreenMatic
  • Oase FiltoMatic

FiltoClear is popular for discreet, pump fed installations where space is limited.

Is Oase FiltoClear suitable for koi ponds?

FiltoClear can work for lightly stocked koi ponds. However, for heavily stocked koi ponds, drum filtration such as ProfiClear Premium is generally more suitable due to superior mechanical waste removal.

What size Oase filter do I need?

Filter sizing depends on:

  • Pond volume
  • Fish stocking level
  • Feeding rate
  • Desired turnover rate

Under sizing is a common cause of poor water clarity. Always size filtration based on actual fish load rather than just pond volume.

How energy efficient are Oase AquaMax pumps?

Oase AquaMax Eco pumps are designed for low electricity consumption and high output efficiency.

  • AquaMax Eco Classic offers reliable circulation for standard ponds.
  • AquaMax Eco Premium features electronically adjustable flow control.
  • AquaMax Eco Expert is designed for large ponds and commercial installations.

Adjustable flow allows reduced energy use during colder months.

What is the difference between AquaMax Eco Premium and AquaMax Eco Expert?

AquaMax Eco Premium is suited for medium to large ponds requiring energy efficient filtration and waterfall supply.

AquaMax Eco Expert is designed for larger installations, higher head heights and commercial or estate pond systems.

Expert pumps provide higher flow capacity and durability in demanding environments.

How do Oase Bitron UVC clarifiers work?

Oase Bitron C, Bitron ECO and Vitronic UVC clarifiers expose pond water to ultraviolet light.

This destroys free floating algae cells that cause green water and helps reduce harmful pathogens.

Proper pairing of UV wattage and pump flow rate is critical for effective results.

Why is my pond still green after installing an Oase UVC?

Possible causes include:

  • UV unit undersized for pond volume
  • Excessive flow rate through UV
  • Expired UV lamp
  • Poor mechanical filtration
  • High nutrient levels

Ensuring correct installation and maintenance is essential.

Can Oase products be used for lake aeration?

Yes. Oase Lake Aerators and PondJet systems are designed for large ponds and lakes.

They improve oxygen levels, reduce stratification and support healthier aquatic ecosystems.

Lake fountains also combine aeration with visual display.
