Ruby Reef's "Kick Ich"

I have a bottle of this stuff on my desk, and I'm going on vacation
tomorrow for a week. I can't setup the hospital tanks by tomorrow and
treat w/ copper because I can't locate a copper test and I'm not sure
how chemistry oriented my house keeper is.

I googled around and it seems to have mixed results. Some claim
success, but these are the same people that claim that Ich is always in
the tank and "there's nothing you can do about it", so I have to be
suspicious of what qualifies as "success". Others are reporting fish
deaths and algae blooms after treatment.

I'm leaning towards returning the bottle for a $20 refund.

Any thoughts?
