First and foremost, dishonesty is bad, either from the moral or legal standpoint. Moral dishonesty and the product efficacy against gha/bubble algae are different subjects to me. You can far cry or boycott all you want.
Vibrant DOES help me clean up green hair, bubble algae and no side of effect of that I aware in my mixed reef tank, besides destroying my chaetos (it was my fault for I forgot to remove it before dosing). Have been using it for more than 2 years. As long as it gets the job done, I personally don't care its algaecide, snake oil, voodoo magic, or whatever. It works and that's all it matters. I will keep using it when the time calls for.
Btw, coralline algae grows fine in my tank during all these Vibrant applications, just you know.
