We just got some to try. Smells like vicks though, never thought I'd add something to the tank that smells like stuff I put on my chest when I get a cold. Works for me, hopefully it will work for the fish too.. Lisa
The only thing that I would worry about is the little mushrooms and other types of inverts and corals surviving the medication....mine went through quite a bit of shock after medication, but finally are coming out again.
Later!
