I have used pretty much all of the common ones. I don't see much of a difference. I have coral rx pro right now. I have used seachems, ME dip, Revive, coral rx, coral rx pro, freshwater, and have sold brightwells but have not personally used them.
The only one I would avoid is Bayer because I don't feel like using insect poison when I can used something actually meant for what I am doing.
