MT Nitro Ring Lotus Root Nitro RIng 1L for fresh water Size: 40x20mm with zip mesh bag 12boxes/CTN

The Lotus Root Nitro Ring II features with oblique section plus super porous, to maximize space for nitrobacteria growth and eliminate 
harmful substance. It builds an exhaustive and healthy microsystem, and maximizes filter space at the same time. Featured with oblique section plus super porous, to maximize space for nitrobacteria grow and eliminate harmful substance at the final step. Builds an Exhaustive & Healthy Micro System Maximizes filter space

Rough surface- The texture helps nitrifying bacteria attach and grow, thus greatly accelerating the establishment of a nitrification system
Special lotus hole structure- Helps the water to carry nitrite and nitrate into the nitrification ring for efficient denitrification reactions, and uses the anaerobic bacteria cultured in the micropores inside the nitrification ring.
Oblique section- Save more filter space-. More filter space can be saved due to the oblique section, and the beveled nitrification rings 
accumulate together, which can disrupt the flow of water and prolong the flow of water in the area where the nitrification ring resides, so as to improve the filtration efficiency.
Micro hole - Benefit to cultivating bacteria - The micro hole helps to cultivate the aerobic nitrifying bacteria community on the surface of nitro rings, while the internal micropores are conducive to the cultivation of anaerobic bacteria for denitrification reactions, which decomposes NO3 into nitrogen and oxygen through denitrification.
