Nano-Sponge Filter is a high performance filter with wide range of use for aquarium fishes such as guppy, neon, shrimp and all kinds of fish fries. Nano-Sponge with fine porous poles maximised the colonization of beneficial bacteria which will help to keep water clear. Direction: Rinse off dirt on the sponge with tap water before use. Fix the filter inside the aquarium and connect to an air pump with the connector. Use a check valve to avoid water back flow in case of power failure. Maintenance: Nano-Sponge filter can be used repeatedly. Rinse the sponge with aquarium water and squeeze slightly, tap water might kill the beneficial bacteria on the sponge.
