I am not sure this would work with Amazon swords. I have managed to successfully grow water lettuce, anubias, java moss, and subwassertang with no substrate or ferts. There are fish and shrimp in the tanks. The water lettuce and java moss are doing better in this setup than I've had with substrate tanks. The tanks have been going strong for over a year now.
As far as rooted plants, I've also started a pothos experiment but the stems and leaves are not submerged. That is going well so far.
