Sintered glass cylinder media with an excellent porosity for mechanical and biological filtering of fresh and saltwater aquariums. CRYSTALCIL MINI has a dual function: mechanical filtering as it traps coarse impurities carried by the water (leaves, excess food, excrement), biological filtering thanks to its porous characteristic which offers a large surface area to help and promote bacteria development which then break down the organic substances.
