JBL MicroMec is a highly porous bio filter material made from sintered glass which allows the efficient biological breakdown of pollutants. It is therefore particularly good for intensive biological long-term filtering in freshwater and marine aquariums. The special conical tunnel pore structure provides beneficial cleansing micro-organisms with the best possible conditions for colonisation. Compared to rings, the greater material thickness of the irregular pellets allows different bacteria to colonise the filter in layers. Ammonium and nitrite are efficiently broken down in the outer layers, whilst the optimum conditions for the bacterial breakdown of nitrate are created in the inner section. The optimum bulk density is extremely effective even in small filters.

• High Quality sintered glass balls for crystal-clear water
• With only 14mm ball diameter, also suitable for small filters
• Conical tunnel pores allow algae-promoting nitrates to be broken down.
• More intensive breakdown of ammonium and nitrite.
• 1 liter has 1500 m2 effective surface, 8 times as much as conventional ceramic pipes
