Justin, hope all is well. I think you got teh id correct. Bruce is right nutrients gotta go somewhere. But they might go into phytoplankton production if not being dyed. I would discard that if you want fish since not working anyway. It is tougher to kill than many algae mats. We have good luck with cooper sulfate liquid mixed with Reward. I posted somehwere about pithophora contorl, pretty similiar deal. Good luck.
