I am currently employing hypo at 1.008 for the treatment of ich. I looked on wetwebmedia and saw that Bob Fenner doesn't think that hypo is a viable treatment to eradicate ich from a system. He is obviously a trusted source when it comes to marine life. Steven Pro advocates hypo for the eradication of ich during quarantine and is also a trusted source. This is my dilemma. I started with cupramine, but lost a coral beauty and a flame angel in the process. Hypo is easier on the fish, but if it does not eradicate the ich, then what is the point. Does anyone have any scientific studies that they can point me to? How about any articles where Steven Pro discusses Fenner's doubts? I am not looking for anecdotal evidence of hypos success. I would like to be able to look at some studies. Thank you, Aaron
