Upgrade your aquarium’s filtration performance and ease of maintenance with the OASE BioStyle filter – a compact hang-on-back (HOB) unit featuring three-stage filtration (mechanical → biological → chemical) and adjustable flow control, suitable for both freshwater and marine environments
Key Features:
Multi-stage filtration system: Each cartridge includes foam for mechanical/biological filtration, chemical media and a polishing fleece.
Quiet, efficient operation and simple maintenance thanks to the disposable cartridge system and cleaning-indicator.
Adjustable flow control lever to match aquarium size and reduce turbulence.
Sleek, space-saving design ideal for tanks where an internal or canister filter is impractical.
Proven build quality with German engineering and Italian assembly.
Choose the correct model variant based on your aquarium size (BioStyle 20 for ~20 gal / ~76 L, BioStyle 30 for ~30 gal / ~115 L, BioStyle 50 for ~50 gal / ~190 L).Install the unit on the rim or back-wall of the aquarium; ensure the cartridge is seated correctly and the flow is adjusted to suit your habitat.
Monitor the cleaning indicator and replace the cartridge when the indicator shows cleaning is required.
For marine tanks, ensure chemical media (cartridges) are compatible with saltwater systems and fit the maintenance schedule.
Perform regular partial water changes and maintain general tank hygiene — the filter helps but doesn’t replace good husbandry.
