Thanks to Deb's advice some time ago, I too have found garlic as the best treatment. I had tried that "kick-ich" a while back and achieved nothing beneficial other than the fact that I did not lose any of my fingers...

I purchase garlic "gel tabs" and cut them open. It works for me and everything smells great !
I wish ya' luck with treatment. Keep the nutrition and water quality optimal and aquarium disturbances minimal, and hopefully they can "ride it out".
