Filters & UVC

Clean Water and Maximum Convenience

A functioning filter is not only crucial for the water quality of the aquarium, but it also ensures the survival of the inhabitants. Filters maintain a balanced ecosystem, generate current, absorb turbid substances, and enrich the water with oxygen. the filters clean the water by utilizing mechanical and biological filtration. Mechanical filtration removes suspended matter and coarse dirt particles, such as feed residues, plant parts, and animal waste. Biological filtration converts or removes bacteria as microorganisms settled in the filter feed on organic matter.

OASE's range of both internal and external filters provides you with many options for maintaining a clean and healthy ecosystem for your fish and plants. Internal filters are placed inside the aquarium and are particularly suitable for small aquariums or if there is no space outside the aquarium. They can also function as an additional filter. A key advantage is that no visible hose connections interfere with the aquarium's overall aesthetic. External filters are placed outside the aquarium, thus making them easily accessible from the outside. These filters can easily be hidden in an under-cabinet. External filters usually operate with different filter media in several layers. OASE external filters are characterized by high filter performance and long service life.

For even more cleaning, OASE offers the ClearTronic UV Clarifier. UV Clarifiers ensure clear, bacteria-free aquarium water through UVC radiation - ideal for preventing diseases that can affect aquarium inhabitants.

TIP! The basis for the selection of an aquarium filter is the size of the aquarium, measured by the amount of water. In general, it is better to choose an oversized filter system than a small one. 

TIP! Be patient... 
Important microorganisms that biologically clean the water settle on the filter foams in your aquarium filter. These microorganisms feed on minute particles that we perceive as debris - a new or recently cleaned filter only attains its full performance capacity gradually; the microbiology must first establish itself.
