KW Zone Dophin SF-15 Nano Sponge Filter

Nano-Sponge Filter is a high-performance filter with a wide range of uses for aquarium fish such as guppies, neon tetras, shrimp, and all types of small fish. The nano-sponge filter features fine porous columns that enhance the colonization of beneficial bacteria, which will help maintain water clarity. Directions: Rinse the dirt off the sponge with tap water before use. Install the filter inside the aquarium and connect it to an air pump using the connector. Use a check valve to prevent backflow of water in case of a power outage. Maintenance: The nano-sponge filter can be used repeatedly. Rinse the sponge with aquarium water and gently squeeze it, as using tap water may kill the beneficial bacteria present on the sponge.
