Using environmental high density sponge filter, can absorb dirt, quickly resolve fish feces and eliminate smell in water. Using with air pump, can improve water oxygen level, achieve oxygenation and bio-filtration double effect, keep water clean. Aerobic bacteria colonize the sponge providing a bacterial substance to facilitate the nitrogen cycle.

In addition, the sponge traps larger waste particles mechanically cleaning the water without trapping baby fish.
They are useful for breeding filter or as secondary filter. They can be used as pre-filtration unit by fitting to an external or a top filter.

Note:
1. Soak for 5 minutes before use with aquarium water, easy to digest form colonies of bacteria.
2. Must use aquarium water when rinsing the sponge, do not use hot water.
