Yes the theory is that with in the LR there will be anaerobic bacteria that converts Nitrate to Nitrogen. This is not always possible, with high bioloads and rock too dense or too porous.
that is why 'we' have added DSB, Refugiums, and Coil denitrators. But having Rock that can not convert Nitrate to Nitrogen does not render it useless J
