How is the sandbed fauna doing in the tank? Stands to reason that if it is truly a consumable phytoplankton, there should be an explosion of life in the tank?

Doug, Jayson, I'm not saying that a clam wouldn't consume whatever is in there, just that it could be an expensive experiment for both participants. I stand by the gorgonian comments, there's no way one or two or even more would clear that tank up.
