## Long description

The sera Multi fil 350 is a flow-through aquarium filter designed for mechanical and biological filtration in freshwater and planted aquaria. This compact external unit routes tank water through layered filter media to capture particulate matter and provide surface area for beneficial bacteria, supporting clearer water and more stable water parameters in small to medium tanks.
Advantages
The filter combines mechanical filtration to remove debris with biological filtration to support nitrifying bacteria, helping control ammonia and nitrite levels. Its compact flow-through design enables straightforward installation and quiet operation outside the aquarium. The construction allows regular media arrangement and replacement without disturbing the tank environment, and the unit is suitable for planted setups where gentle flow and stable water quality are important.

How to use
Install the sera Multi fil 350 according to the manufacturer’s instructions, connecting inlet and outlet hoses between the aquarium and the unit so water constantly flows through the filter media. Arrange appropriate mechanical and biological media inside the chamber, ensuring water passes through the layers in sequence. Prime the unit if required and verify that flow is steady and leak-free before leaving the system to operate. Monitor water flow and the condition of the media at regular intervals and replace or clean media when performance declines.
Usage recommendations
For consistent performance, routinely check and maintain the filter media, avoid overfeeding fish to reduce particulate load, and select media suited to your tank’s bioload and plant requirements. Ensure hoses and connections are secure and position the filter where it can operate quietly and accessibly for maintenance.
