I doubt it. I use spirulina to feed my live bearers and never had a BG outbreak in any of those tanks.

The trick with BG algae is that you often don't get all of it the first time around and it comes back. In my case, it was retreating down into my substrate (aquasoil) and not enough antibiotic would get to it.
