JBL SintoMec is a highly porous bio filter material made from sintered glass, which is particularly good for intensive biological long-term filtering in freshwater and marine aquariums. The special conical tunnel pore structure together with a wall thickness of 5 mm offers beneficial micro-organisms the best possible conditions. This guarantees efficient breakdown of the pollutants ammonium, nitrite and, with reduced current flow, also nitrate. The result is excellent water quality. The ring shape offers optimum water flow and long service life.

• High-quality sintered glass rings for intensive biological water clarifying.
• Internal hole diameter only 5 mm, resulting in thicker wall depth and providing more effective surface for bacteria which breakdown pollutants.
• 1 liter has 1200 m2 effective surface, 5 times as much as conventional clay tubes.
