Wisteria, water sprite and hornwort are all very good nitrogen consumers.

Fast growing plants with shallow roots like stem plants work well. Some plants are more root feeders and some are leaf based feeders. Do some research and pick plants that get some of their nutrients out of the water and not the soil. Finding plants that will tolerate the 80+ temps that the Discus like is the hard part.

Some people say Devil's Ivy (Epipremnum aureum) works very well. It's a house plant and whilst it can grow submerged you would normally just submerge the roots. People let the actual stems/leaves grow up and out over the hood of the tank.
