An interesting ad aimed at fooling people into thinking there is something to this magic elixir. I must agree with Jacko on this one. I have tried using the stuff in an emergency and found it worked so well that I had to do an emergency water change the next day to save my fish. Once I got home from the convention, the reason I was trying it, I used a clone form one of my filters and the new tank settled right down.
Final score:
Filter clone 1, Cycle 0.
