KW Zone Dophin SF-33 Nano Sponge Filter

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.

Where it works best

Because the sponge cannot suck in tiny animals, it is a safe choice for shrimp tanks, fry-rearing tanks, breeding setups and hospital tanks. It is also useful as a back-up: keep it running in the main tank for a few weeks so it fills with bacteria, then move it to a new or quarantine tank for an instant head start. You will need an air pump, airline tubing and ideally a check valve; adjust the airflow so the surface ripples gently without blowing small fish around.
