Rich,

Thanks very much for your reply, but sorry I didn't quite absorb it all. Noted about invasive species warning though, but yes they are found locally (I think native).

Water lettuce is it a monocote?
Hyacinth monocote?

The problem you mentioned is that their roots might not go directly with Aldos, but if they can be quite near to Aldros they can give some benefit? (Again sorry to be a bit thick tonight).

TTFN
