MarinePure's 1.5-inch porous ceramic spheres provide a substrate for beneficial bacteria in compatible canister filters, sumps and wet/dry filtration systems. Choose 2 quarts or 1 gallon of media.

Why Choose Spheres?

• Individual pieces are easy to arrange in a suitable media chamber.
• Suitable for freshwater and marine systems.
• Can be used submerged or in compatible trickle-filter applications.
• Provides biological filtration surfaces for ammonia and nitrite processing.

Setup and Care

Check that your chamber can accommodate 1.5-inch spheres. Rinse away dust before use and follow the manufacturer's rinsing directions. Provide mechanical prefiltration and rinse gently in aquarium water as debris accumulates. This media is not intended for moving-bed filters.

Allow biological filtration to establish and continue monitoring ammonia and nitrite. Replace established media gradually rather than all at once.
