The AQUAEL FZN PRO 400 is a modern cascade (hang-on) filter designed for quiet and efficient filtration in smaller aquariums up to 75 litres. Suitable for both freshwater and marine tanks, it offers reliable performance combined with exceptional ease of use. A key feature is its fully submerged motor, which keeps the noise level at only around 31 dB. This makes it nearly silent - ideal for living rooms, bedrooms, and office setups. The filter requires no priming, it starts automatically once plugged in. In case of a power outage, it restarts on its own, ensuring continuous filtration without intervention.
The adjustable intake tube and flow control knob provide flexibility in flow and water level regulation. The filter chamber can be filled with cartridges or loose media depending on your needs. Maintenance is simple thanks to the easily accessible lid and quick-removable media container. The AQUAEL FZN PRO 400 is the perfect choice for aquarists looking for a compact, silent, and powerful filtration solution.
