Ray,
Glad to hear you ordered some... I must have pitched the last of what I had.
Yes... I did do the treatment, but the tank I was treating only had a few acros, so I pulled them all out and treated in a hospital tank. I would have to re-read the protocol, but I think I did the initial dose and then a re-dose without water changes, and the treatment lasted about twice as long as the expected life cycle of the bugs.
If you have any other questions, e-mail me or call me.
Adam
