Seachem Denitrate 1 Liter Container Denitrate is an economical,
natural, porous material with a pore distribution and geometry
that promotes both aerobic nitrification within the first few
millimeters of depth and anaerobic denitrification at the core.
The material has a high surface area and supports a high density
of bacteria. Although de nitrate has capacity to trap nitrate,
this, as with other nitrate retaining materials, such as certain
zeolites and synthetic resins, is quite limited and the primary
mechanism of nitrate removal is anaerobic. Detailed description
below: Why It's Different Live rocks or reef rocks remove
nitrate by anaerobic denitrification. de nitrate removes nitrate
by the same process. Efficiency is magnified several folds by
forcing the water to filter through the porous de nitrate. As
with reef rock, anaerobic conditions are achieved by the
porosity and the depletion of oxygen by the aerobic process at
the surface. Excessive flow rates should, therefore, be avoided,
as they may impede
