First, as Jerry Baker pointed out, denitrators are generally unnecessary for a planted tank.  In fact, they could be detrimental because they would remove the nitrogen that our plants need.

Second, denitrators need organic carbon to do their work.  CO2 or carbonates won't help at all.  You can feed the denitrifiers all the CO2 you want, but it won't help.
