talev Posted September 2, 2013 Share Posted September 2, 2013 It is basically ferric oxide, which may help to reduce ammonium production and indirectly reduce no3, but it is doubtful whether it actually lowers no3 significantly. See e.g. http://ecosystems.mbl.edu/ses/2007%20projects/carpenter.pdf One way it may help no3 is through its many anaerobic surfaces for denitrification, but we probably need a large volume of these and a really slow flow rate.
