## Long description

sera internal sponge filter L 150 (model SE-08520) is a compact internal filtration unit designed for biological and mechanical filtration in small to medium aquariums. The porous sponge medium traps suspended debris while providing an extensive surface area for colonization by beneficial nitrifying bacteria. The unit is suitable for freshwater systems, breeding tanks and shrimp setups where a gentle water flow and low suction are preferred. Installation is intended inside the tank, and the design minimizes disturbance to inhabitants while maintaining effective water clarification and biological filtration.
Advantages
The internal sponge filter combines mechanical and biological filtration in a single compact module. Its sponge captures particulate matter and reduces cloudiness while offering a stable habitat for beneficial bacteria that support the nitrogen cycle. The low-flow output and soft suction make it appropriate for delicate fish, fry and invertebrates. The compact form factor facilitates discrete installation inside the aquarium and simplifies maintenance: the sponge can be rinsed and reused without replacing media frequently.
Suitable for
Small to medium freshwater aquariums
Breeding tanks and fry compartments
Shrimp and invertebrate tanks requiring gentle flow
Quarantine tanks and hospital setups
Supplemental filtration in planted aquaria
Key specifications
Filtration type: combined mechanical and biological
Filtration medium: porous sponge
Installation: internal, submerged inside the aquarium
Recommended aquarium size: small to medium tanks
Flow characteristic: low and gentle circulation suitable for delicate inhabitants
Maintenance: sponge is washable and reusable
How to use
Mount the sponge filter inside the aquarium according to the manufacturer’s mounting provisions so that it is fully submerged and positioned to provide gentle circulation without direct strong currents on inhabitants. Connect to an appropriate air pump or internal drive if required by the model, and prime as instructed to establish steady flow. Periodically rinse the sponge in tank water during maintenance to remove accumulated detritus while preserving beneficial bacterial colonies. Inspect fittings and seals regularly to ensure continued performance.
Usage recommendations
For optimal biological filtration, avoid cleaning the sponge with tap water containing chlorine; instead rinse in conditioned aquarium water. Pair the filter with an appropriately sized air pump or drive to ensure steady but gentle flow. Monitor water parameters after installation and during cycling to confirm effective ammonia and nitrite control.
