Ruby reef rally useful to fight dinos?

[jeffchapok]

Their website claims "RALLY is a very effective broad spectrum treatment designed to be used directly in the display tank to eliminate external parasites, dinoflagellates, marine velvet, clownfish disease, gill flukes, etc. on fish."

My fish are all healthy, but I'm fighting a dino outbreak in my tank, mostly concentrated on the substrate. If RRR kills dinos on fish, would it likewise be effective at fighting dinos at large?

I don't think it's a viable treatment for dinos and it most certainly wouldn't be reef safe(if you have corals).

That could be dinos but honestly looks more like cyano/spirulina to me. If you could get a specimen and take a picture under a microscope we could tell if it's dinos, what species and therefore be able to direct you towards a good treatment plan.
