OASE BioStyle Thermo 30 Grey combines efficient multi-stage aquarium filtration with an integrated aquarium heater in one compact hang-on-back system. Designed for aquariums up to approximately 115 L / 30 US gallons, it is an excellent solution for aquarists who want effective filtration and heating without placing a separate heater inside the aquarium.
The BioStyle Thermo 30 provides mechanical, biological, and chemical filtration while offering adjustable water flow, a telescopic intake, and OASE's convenient EasyClean maintenance indicator.
For planted aquariums and aquascapes, integrating the heater into the filter helps reduce visible equipment inside the display, keeping more attention on the plants, hardscape, and livestock.
The defining feature of the BioStyle Thermo 30 is its integrated heating system. Rather than installing a conventional aquarium heater inside the display, the included OASE HeatUp 25 is incorporated into the filter system.
This helps create a cleaner aquarium presentation while reducing the amount of equipment visible around aquatic plants and hardscape. The heater is preset to approximately 79°F / 26°C.
The BioStyle Thermo 30 uses multiple filtration stages to help maintain clean and healthy aquarium water. Its filter cartridges combine filter foam, chemical filtration media, and fine filter fleece for mechanical, chemical, and biological filtration.
Separate 30 PPI biological filter foams provide additional surface area for beneficial bacteria while also helping capture debris passing through the filter.
Built-in flow adjustment allows aquarium circulation to be fine-tuned according to the needs of the aquarium and its inhabitants. This is particularly useful in planted aquariums where excessive current may not be desirable throughout the entire layout.
The telescopic intake can be adjusted to accommodate different aquarium heights, while the hang-on design provides surface movement that can help promote gas exchange.
OASE's integrated EasyClean indicator provides a visual indication when filter maintenance is required, helping take some of the guesswork out of routine servicing.
The accessible cartridge system also makes filter maintenance straightforward without requiring the hoses, valves, and disassembly associated with a traditional canister filter.

The BioStyle Thermo 30 is especially attractive for aquascaped aquariums because the heater is moved out of the display and integrated into the filtration system. This keeps more attention on the plants, hardscape, and livestock while still providing filtration, circulation, and heating.
