I have concluded using the Kick Ich. I lost my 2 Percula's and my Mustard Tang, but everyone else is looking pretty good. My Blue tangs are a bit beat up from scatching themselves, but even they are recoveing nicely now. I did a water change and put carbon in last week to clean out the Kick Ich, and over the weekend I turned back on my UV. I still won't add anything for a few weeks to make sure everyone is alright. So far so good though!!
