biOrb Pearl Media - Filter Pearls

biOrb Pearl Media is a biological filter material with a smooth surface, ideal for bottom-feeding fish and shrimp. The pearls house beneficial bacteria that activate biological filtration, ensuring clear and healthy water. It does not alter pH and is compatible with all biOrb models and all fresh and saltwater aquariums.

💡 Expert tip: Pearl Media is particularly suitable as an upgrade from standard biOrb ceramic media: the smooth surface is ideal for shrimp that rest on it and feed by scraping the surface biofilm. Never replace all filter media at once: change a maximum of half at a time to preserve the bacterial colony and not reset biological filtration.
