OASE FiltoSmart Thermo External Canister Filter

The OASE FiltoSmart Thermo is a compact and efficient external canister filter that combines multi-stage filtration with integrated aquarium heating. Designed for aquariums from 100 to 300 litres, the FiltoSmart Thermo provides effective mechanical and biological filtration while keeping both the filter and heater neatly outside the aquarium.

With its integrated OASE HeatUp adjustable heater, the FiltoSmart Thermo helps maintain a stable aquarium temperature without the need for a separate heater inside the display. This makes it an excellent choice for planted aquariums, aquascapes and display tanks where a clean, uncluttered appearance is important.
