When I was a grad student, we were actually doing a study on growing floating kelp beds outside the Victoria sewage outlet as a means of nutrient export.
But yeah, I don't think I'd want to add anything like that into my tanks mainly due to leaching of toxins into my reef tank water, as well as the toxins being fed to my fish. If it was further north in a secluded bay then I'd probably do it if necessary.
