BioStyle 50
The OASE BioStyle 50 is a powerful hang-on-back aquarium filter designed for aquariums up to 50 gallons (190 liters). Combining German engineering with Italian manufacturing quality, this filtration system delivers reliable multi-stage water purification in a compact, modern design. It is ideal for freshwater community tanks, planted aquariums, and marine setups that require consistent water clarity and biological stability.
The BioStyle 50 features an advanced multi-stage filtration system that integrates mechanical, biological, and chemical filtration. The mechanical stage efficiently removes debris, uneaten food, and fish waste, helping maintain crystal-clear water. The biological filtration media provides extensive surface area for beneficial nitrifying bacteria, which convert toxic ammonia and nitrite into safer nitrate, supporting a stable aquatic ecosystem. The chemical component helps reduce discoloration and dissolved impurities, further improving water quality.
Its cartridge-based system, combined with biological foam inserts, maximizes filtration efficiency while keeping maintenance simple. Cartridges are easy to access and replace, making routine cleaning fast and beginner-friendly. An integrated cleaning indicator visually alerts users when servicing is required, helping maintain optimal performance.
The adjustable flow control allows aquarists to customize water movement according to livestock needs. This flexibility makes the BioStyle 50 suitable for active community fish, planted aquariums, and species that require moderate water circulation. Proper flow adjustment ensures adequate oxygenation without creating excessive current.
A telescopic intake tube adapts to different aquarium heights, providing installation flexibility across various tank sizes. The hang-on-back design preserves internal aquascape space and eliminates the need for bulky internal filters or external hoses. A built-in leveling support system ensures secure and stable mounting.
Engineered for quiet and energy-efficient operation, the BioStyle 50 is ideal for living rooms, offices, and bedrooms. Its durable construction ensures long-term reliability and consistent filtration performance.
Whether you are setting up a new 50-gallon aquarium or upgrading your filtration system, the OASE BioStyle 50 delivers efficient water purification, easy maintenance, and a sleek design that complements modern aquariums.
