Sera Internal Filter L60
The Sera Internal Filter L60 is an air-driven sponge filter designed for efficient aquarium filtration. Operating as a mammoth or airlift pump, it uses an air pump to push water through a hose into the standpipe. As air rises, it pulls aquarium water upward, which then filters back through a fine mesh sponge. This sponge offers an excellent surface for mechanical purification of the water. Additionally, the specially designed sponges harbor nitrifying bacteria crucial for breaking down pollutants. These filters are particularly suitable for nurturing larvae and young fish, protecting them from being sucked into standard filters due to their tiny size and unique swimming patterns.

FAQ
How does the air-driven system work in the Sera Internal Filter L60?
The filter uses an external air pump to push water through a hose into a standpipe. As air rises, it creates a suction effect that pulls aquarium water upward. The water then passes through a fine mesh sponge for mechanical filtration and supports bacterial growth.
Is the sponge filter suitable for use with fry or small fish?
Yes, the Sera Internal Filter L60 is specifically designed to protect fry and young fish from being sucked into the filter due to its fine mesh and gentle filtration method.
Can this filter be used with an external air pump?
Yes, the filter requires an external air pump to operate. The air pump must be connected to the hose to create the necessary airflow for water movement.

The filter works well for my community tank with neon tetras and baby guppies. The sponge prevents the fry from getting sucked in, and the water flow is steady. I’ve noticed better water clarity after a few weeks of use.
William Bond –
Great for small fish and new arrivals. The sponge stays clean and the filtration is effective without creating strong currents. I only need to clean it every few weeks.

I used this filter for my breeding tank. The fry survived without being lost to the filter. The bacteria colony developed quickly and water quality improved noticeably.
