Mountain Tree Fresh Lotus Root Nitro Ring Size: 45x28x20mm 5Liters/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.

• Perfect choice for small filter system
• Excellent biochemical filtration effect
• Special design for maximum filter efficiency
• Premium non-toxic material

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.

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.

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.
