I have edited my initial post. FOR THE LAST TIME, I apologize for my initial post. It was not meant to be deceptive. As far as hydrilla in the pond, it was indeed hydrilla and the owners had tried other products that were unsuccessful at solving the problem, so I understand how you would feel skeptical. I am not here to argue or cause a commotion. I strictly wanted to post a solution to a problem and hear feedback from others who have tried similar solutions. If people have tried microbial products and were unsatisfied, I would like to hear about.

thanks
Casey
