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.
