CerMedia MarinePure 56L Half Drum Sphere

Industrial-Strength Bio-Media for High-Capacity Filtration

The CerMedia MarinePure 56L Half Drum Sphere is a professional-grade solution for advanced biological filtration. Ideal for large aquariums and high-biomass systems, these 1.5" ceramic spheres provide unmatched surface area for beneficial bacteria to thrive—ensuring the effective breakdown of ammonia, nitrite, and even reducing nitrate levels.

Engineered with Thin Bio-Film Technology, each sphere promotes faster nutrient access, prevents clogging, and maintains continuous water flow through its porous structure—unlike dense alternatives where water flows around instead of through.
