I got a PM asking about this product. And decided to write about it.

While we were bumming around That Fish Place, That Pet Place in Lancaster, after the show, Nate came up to me with a bottle, saying look at this, this is what you need.
It was Euthanase.
He was right, though the bottle was huge, a pint. But I was all hellz yeah, you're right, so I bought it. Little did I know there was a teeny bottle that was only 2 bucks that they also sold, but that is besides the point.
Euthanase is made by Aquarium Products.
It IS a clove based formula, but it is made to disburse in the water fast and easily, so it is more effective.
It can be bought from the above store, however, that is the only place I have seen it available on a net search.
I can call the company and see if they sell to any other place, but if they don't, I myself can be a supplier
