Product Questions

I would like to use this in a 40G QT tank to prevent any diseases for my new fish. The fish I buy I assume will not show any signs of disease but I would like to prevent any outbreaks before I transfer them to my main display tank. Will this be a good option for that? Does this product comes with instructions on dosing? Thanks!
