BioStyle Thermo 50

The OASE BioStyle Thermo 50 is a premium hang-on-back aquarium filter with an integrated heater, designed for aquariums up to 50 gallons (190 liters). This all-in-one system combines efficient multi-stage filtration with precise temperature control, providing stable water conditions while maintaining a clean and modern aquarium appearance.

Engineered in Germany and manufactured in Italy, the BioStyle Thermo 50 integrates mechanical, biological, and chemical filtration into one compact external unit. The mechanical stage removes debris, uneaten food, and suspended waste to maintain clear water. The biological media supports beneficial bacteria that convert toxic ammonia and nitrite into safer nitrate, ensuring long-term biological stability. The chemical component helps reduce discoloration and dissolved impurities for improved water quality.

The standout feature is the integrated adjustable heater, built directly into the filter housing. This eliminates the need for a separate in-tank heater, preserving aquascape aesthetics and maximizing internal space. Stable temperature control is essential for tropical freshwater fish, shrimp, and planted aquariums, and the Thermo 50 delivers consistent heating performance.

Its cartridge-based filtration system makes maintenance simple and efficient. Replaceable multi-stage cartridges combined with biological foam inserts ensure optimal filtration while remaining easy to service. An integrated cleaning indicator alerts users when maintenance is required, helping maintain peak performance.

The adjustable flow control allows customization of water circulation based on livestock needs. This flexibility makes the BioStyle Thermo 50 suitable for community fish, planted aquariums, and species requiring moderate water movement. Proper circulation ensures effective filtration and oxygenation without excessive current.

A telescopic intake tube adapts to different tank heights, and the hang-on-back design preserves internal aquascape space while keeping equipment discreet. Quiet and energy-efficient operation makes it ideal for living rooms, offices, and home environments.

Whether setting up a new tropical aquarium or upgrading filtration and heating in an existing tank, the OASE BioStyle Thermo 50 offers reliable performance, integrated heating, and a sleek design in one compact solution.
