I think my post #11 above gives an obvious reason why UV can't do anything more than provide a little help. Much of that post comes directly from Snorvich's writings and insight. One thing UV does do very well (outside of clarify water) is to give the appearance and false hope that something positive is being done and its just a matter of time before the UV kills all of the ich. This delays real treatment and can be the difference between a good outcome and a tankful of dead fish.
