This sp. is grown as an emerse form. Try water cress. This is about the best 
for removing nitrates & you can eat it. Buy it from a supermarket & put 
roots in water. New growth quickly appears.
I'm presuming you can get this in the US.
Floating plants seem to remove nitrates efficiently. Ceratopteris, water 
cress & duckweed are useful & can be put on the compost heap. A balance 
between plants & regular water changes is useful.
