UVC clarifiers, filters & aerators
Our advanced filtration technology is designed to aerate, clean, clarify, and oxygenate pond water for a healthy and balanced aquatic environment.
UVC clarifiers are installed ahead of the filtration system, where ultraviolet light helps reduce suspended algae, bacteria, and other microorganisms before water enters the main filter. This improves overall water clarity and enhances filtration efficiency.
Our modular, expandable flow-through filter systems are engineered for larger bodies of water, including swim ponds with volumes of up to 530 m³ and koi ponds up to 100 m³. These scalable systems make it easy to match filtration capacity to the specific requirements of your pond.
As a general guideline, larger ponds can support more natural biological processes that contribute to ecological balance. However, effective mechanical and biological filtration remains essential to maintaining consistently clear and healthy water conditions.
Drum filter
Discover the ultimate in flexibility for demanding pond owners with the Oase drum filter. Engineered for top-tier filtration performance and exceptional ease of use, this system is an ideal solution for large swimming ponds.
Koi enthusiasts, in particular, place great importance on maintaining a healthy environment for both fish and plant life. With Oase’s intelligent and powerful drum filter systems, ponds up to 530 m³ and koi ponds up to 100 m³ can be efficiently and reliably kept clean.
Pressure filters
Watercourses have a natural height difference. Pressure filters receive the water via the watercourse pump, clean it and convey it back up to the source thanks to the constant water pressure. The actual filter is buried up to the cover outside the water. The BioPress filter set with pump is designed for smaller bodies of water of up to 10 m³ and is very easy to maintain. FiltoClear is available as a single filter or as a set. They are suitable for bodies of water up to 30 m³. They have better performance and a higher pumping capacity, but are just as easy to operate as BioPress filters. Each model comes with a clear water guarantee from Oase, and some are also suitable for small koi ponds.
Underwater filters
Our underwater filters are designed for ponds with a capacity of up to 9 m³ and 4.5 m³ with fish stock. In addition to the filter elements for the mechanical and biological purification of the water, the integrated UV lamp removes germs and floating algae. Bacteria, viruses and fungi are also removed. The filters are very easy to remove for maintenance. All Filtral UVC underwater filter models also have a built-in pump with a height-adjustable fountain attachment for water features.
Filter foams
Filter sponges are the heart of any pond filtration system. They provide a surface where beneficial microorganisms can thrive, breaking down harmful nutrients and converting them into nitrates that support healthy plant growth.
Our filter sponges feature consistently uniform pore sizes, ensuring steady, even water flow throughout the system. All sponges are suitable for ponds with fish stocking.
Although they are designed for long-lasting performance, filter sponges should still be replaced regularly to keep your filtration system operating at peak efficiency.
UVC clarifiers
We offer four different UVC clarifiers designed for modular and customizable flow-through filter systems. Their UV light effectively eliminates floating algae, bacteria, and other harmful microorganisms.
The Oase Bitron Eco operates intelligently, activating only when needed. This smart functionality can help reduce energy consumption by up to 50%, delivering efficient performance while lowering operating costs.
Aerators
During warm summer months, aquatic life and plants require significantly more oxygen than usual. To help maintain healthy conditions, we offer a range of pond aerators designed for different pond sizes and needs.
Oase AquaOxy and OxyTex systems can also be combined for enhanced oxygenation. The AquaAir 250 is especially well-suited for targeted aeration in areas up to four meters deep. For larger bodies of water, the AirFlo floating aerator combines efficient oxygen supply with attractive fountain effects, delivering both performance and visual appeal.
Ice preventers
Our Oase IceFree models help maintain a stable oxygen supply and proper aeration in your pond throughout the winter months.
The 4 Seasons model is designed for year-round use, offering multiple functions. In winter, it keeps an area of water ice-free even in temperatures as low as –20°C. During the summer, it can be used as an attractive water feature.
The Thermo model is ideal for shallower ponds. While it does not create a fountain effect, it includes an integrated frost monitor. A sensor activates when freezing conditions are expected, making it highly energy-efficient and reliable for winter protection.
