Bio Ceramic Rings 15x20mm

Bio Ceramic Rings are a premium biological filtration medium made of porous ceramic with an active surface area of 800 m²/L. Their advanced pore structure provides an ideal habitat for nitrifying bacteria (Nitrosomonas, Nitrospira) that convert toxic ammonium (NH₄⁺) and nitrites (NO₂⁻) into safe nitrates (NO₃⁻), ensuring crystal-clear and healthy water.Designed for use in all filter types, these rings ensure perfect water flow, oxygenation and nutrient distribution — ideal for densely stocked aquariums and ponds -Highly effective biological filtration – supports breakdown of harmful nitrogen compounds.–800 m²/L active surface area – promotes rapid bacterial colonization.-Reduces NH₄⁺, NO₂⁻ and NO₃⁻ levels for improved water quality.-Maintains a stable aquarium ecosystem – perfect for fish-dense tanks.-Optimized ring size (15×20 mm, 7 mm hole) – ensures water circulation and aeration.-Compatible with internal, external & pond filters.-Ideal for freshwater & marine aquariums.
