Protect your delicate fry and sensitive livestock with the Ocean Free Bio Foam Sponge Filter, an innovative multi-layered filtration solution engineered specifically for small, community, or breeding aquariums. Designed to provide exceptional bacterial colonization without generating excessive water turbulence, this filter ensures a stable and secure environment for species such as Discus, dwarf shrimp, and newborn fry.

Featuring a smart design where the entire surface area of the Bio-Foam works actively to eliminate dead spots, it easily connects to standard airline tubing using an air pump, powerhead, or hang-on filter setup.

Note for Beginner Aquarists: Sponge filters are the gold standard for beginners because they are virtually foolproof. They provide safe mechanical and biological filtration without the risk of small fish or fry getting sucked into an impeller, and the sponge elements can be easily rinsed and reused during routine water changes.
