CerMedia MarinePure is ceramic sphere bio-filter media designed to support aquarium filtration, supplied in a 2-quart pack with 1.5-inch (3.81 cm) spheres.

• One sphere has the same surface area as 1,350 plastic bio-balls — a high-surface-area alternative to conventional plastic bio-balls.
• Open-flow porosity — supports water flow through the ceramic media.
• Designed for ammonia and nitrite removal — supports aquarium water filtration.
• Helps reduce nitrate — adds nitrate reduction to its filtration role.
• For freshwater and saltwater aquariums — suits either aquarium environment.
• Fits wet/dry filters, sumps, and canister filters — works across these filtration setups.

Aquarium filters need bio-filter media that offers surface area while allowing water to pass through. MarinePure spheres are made for aquarium owners setting up or maintaining filtration in freshwater or marine systems, with several common filter types named for use. The ceramic format and open-flow porosity make this a purpose-built filter medium rather than a decorative aquarium item.

What filtration support does MarinePure provide?

MarinePure is intended for ammonia and nitrite removal, and its features also include nitrate reduction. Its porous ceramic structure provides the media’s large surface area, while the open-flow design allows water to move through it. One sphere has surface area equivalent to 1,350 plastic bio-balls, giving buyers a concrete comparison with a familiar plastic filter medium.
