Internal Aquarium Filter HAPPET FILTR ORCA 350 for 60–120 L Tanks

HAPPET FILTR ORCA 350 is an internal aquarium filter designed for tanks with a capacity of 60–120 litres. The unit integrates a compact pump and replaceable media cartridges to provide combined mechanical and biological filtration. It is suitable for freshwater and lightly planted aquariums, helping to maintain water clarity and support the development of beneficial nitrifying bacteria.

Advantages

The filter offers a compact design that mounts inside the tank, minimizing external plumbing and saving space. Replaceable media cartridges simplify maintenance by allowing easy removal and replacement of filtration material without disassembling the entire unit. A built-in pump ensures consistent water circulation across media surfaces to improve mechanical trapping of particles and biological processing. The HAPPET FILTR ORCA 350 is engineered for quiet operation, making it suitable for home aquariums where low noise is preferred.

How to use

Install the HAPPET FILTR ORCA 350 on the inner wall of the aquarium at a depth recommended by the manufacturer, ensuring the unit is fully submerged before powering on. Insert the supplied or compatible media cartridges into the cartridge slot, then connect the power supply and allow the pump to establish circulation. Regularly inspect cartridges and the intake for debris; replace or rinse cartridges according to visual indicators of fouling or the maintenance schedule. When performing water changes, follow standard aquarium husbandry procedures and avoid running the filter dry.

Usage recommendations

For stable biological filtration, start with partially seeded media or transfer a portion of established filter material from an existing system. Monitor ammonia, nitrite and nitrate levels during the initial weeks after installation and after cartridge changes. Clean the intake and impeller housing monthly or as needed to maintain flow; replace media cartridges periodically to preserve mechanical filtration efficiency.
