I've got two kinds of Vallisneria in a sand-substrate Lake Tanganyika tank
and they do just fine.  I've also got Malaysian trumpet snails in there,
if it makes any difference.  I have Java fern and Java moss on the rocks.
For floating plants I have duckweed, Wolffia (a sort of micro-duckweed)
and Limnobium laevigata (frogbit).  All of these grow very well, and I
harvest the frogbit every few weeks and haul it in for store credit.  All
these plants are growing under less that 1.5 watts per gallon, mix of
gro-lux wide spectrum and cool white.
