JAD SF-100 sponge filter or biofilter for aquariums and small ponds.
Diameter: 5.5 cm.
Total height with pipe: 12 cm.
Ideal for fish spawning and shrimp farming. Adaptable to an air compressor or submersible pump, it forms a cascade with air pressure. It filters and oxygenates your aquarium without much water movement. Sponge filters combine mechanical and biological filtration. When used with an air compressor, they circulate water through the sponge, trapping suspended impurities. When the filtered water is returned to the aquarium, only the beneficial particles remain.
During this process, a colony of nitrifying bacteria is formed, making filtration even better
