Nano-Sponge Filter is a high performance filter with wide range of use for aquarium fish such as guppies, neons, shrimp and other kinds of fish fry. Fine porous holes maximize the colonization of beneficial bacteria, to help keep water clear. Can be used repeatedly. Rinse with aquarium water and squeeze slightly.
