Tangs not meant to be or what???

Sure, UV can kill (or otherwise impact the ich lifecycle) but it's never going to clear a system of the parasite.

Fair enough. I have no way of telling if the ich is lying dormant in the tank now.

I have added three decent sized tangs since then. Had to black out the tank for days, add mirrors for distraction, and rework some rock to slow down the fighting.

Having a sample size of one, I really haven't done enough research to say UV's are the answer or not. Just seems to have worked well for me at the time.
