BioStyle Thermo 30

The OASE BioStyle Thermo 30 is a high-performance hang-on-back aquarium filter with an integrated heater, designed for aquariums up to 30 gallons (115 liters). This all-in-one filtration and heating system combines advanced multi-stage water purification with precise temperature control, delivering clean, stable, and healthy conditions for freshwater aquariums.

Engineered in Germany and manufactured in Italy, the BioStyle Thermo 30 integrates mechanical, biological, and chemical filtration into a compact external unit that mounts discreetly on the back of the aquarium. The mechanical stage efficiently removes debris, fish waste, and uneaten food, improving water clarity. The biological filtration media provides a large surface area for beneficial bacteria that convert toxic ammonia and nitrite into less harmful nitrate, supporting long-term biological balance. The chemical filtration layer helps reduce discoloration and dissolved impurities, resulting in clearer and healthier water.

The standout feature of the BioStyle Thermo 30 is its integrated adjustable heater, built directly into the filter housing. This eliminates the need for a separate in-tank heater, keeping the aquarium interior uncluttered and preserving aquascape aesthetics. The heater ensures consistent and stable temperature control, which is essential for tropical fish, shrimp, and planted aquariums that require precise thermal conditions.

The cartridge-based filtration system simplifies maintenance. Multi-stage filter cartridges and biological foam inserts are easy to access and replace, making routine servicing fast and efficient. An integrated cleaning indicator alerts users when maintenance is required, helping maintain optimal filtration performance.

The adjustable flow control allows aquarists to customize water circulation according to livestock needs. This flexibility makes the BioStyle Thermo 30 suitable for community fish, planted aquariums, and species that prefer moderate water movement. Proper flow adjustment ensures adequate oxygenation without excessive current.

A telescopic intake tube adapts to different aquarium heights, providing installation versatility. The hang-on-back design maximizes internal tank space and removes bulky equipment from view. A secure mounting and leveling system ensures stable positioning and reliable operation.

Designed for quiet and energy-efficient performance, the OASE BioStyle Thermo 30 is ideal for living rooms, offices, and home environments where low noise levels are important. Its durable construction ensures long-term reliability and consistent operation.

Whether setting up a new tropical aquarium or upgrading an existing system, the OASE BioStyle Thermo 30 offers efficient filtration, integrated heating, and a sleek design in one compact solution.
