Greetings,
I've been talking to Watershed Consulting out of Missoula, MT. They claim that their BioHaven floating island will capture most of the excess nutrients and reduce or even eliminate the need for mechanical FA removal.
It is a very expensive product with big claims. I would love to hear some first person stories about this technology.
Here is the manufacturers website:
