Description
Dophin Ceramic Ring 905 (400g) is a high-performance biological filtration media crafted to provide an exceptionally large surface area for colonization of beneficial bacteria. Its advanced multi-porous ceramic structure allows water to flow smoothly through each ring while hosting billions of nitrifying bacteria essential for maintaining a stable, healthy aquarium.
These ceramic rings play a crucial role in the complete nitrogen cycle, efficiently breaking down toxic ammonia into nitrite and converting nitrite into the safer form of nitrate. With a denser pack and larger volume, the 400g variant is ideal for medium to large aquariums, canister filters, sump systems, and any setup requiring robust biological support.
