ED what laboratory experiment do you stand by or is your laboratory experiment forums and books, because if so then those are mine to. The sheer volume of sucess with garlic is more than just luck and should suffice in place of an experiment. Post a thread on who uses garlic as a preventative measure to keep away ich and you'll get alot more hits for that witches brew than against it. Do you use garlic? I guess that those people who have had success with kick ick are freaks of nature. Reef safe meds are not the best choice, but some people don't want to deal with the time hypo takes ( specific salt levels, quarantine tanks, water changes, weeks to complete ) and kick ick or similiar products if done right will work ( that is why stores sell them ). You run the experiment and post it in extreme detail, and then you can advise me what to or what not to stand by.
Now maybe you have ran detailed experiments and if so I apologize for questioning you.
