If I'm not mistaken, Nitrate is converted to Nitrogen (Denitrification). My understanding is that LR plays a role in this. There are certain bacteria in LR that support denitrification. The nitrogen is gassed off with good circulation and surface agitation. Not sure if this is relevant to your issues. Just 2 cents for the record.
