I don't have any pictures... but it looks like ich to me. I think it may have been what killed my puffer (before the nem got him). The only reason I don't think it's ich is because I had been dosing Seachem Marine Trace and Reef Trace, both of which have Copper. The last time I emptied my skimmer cup I could smell the copper in it. I would think that high of copper levels would have killed the ich? The corals are all doing amazingly well now. I've backed off the dose quite a bit. I'll clean the skimmer cup tonight and see if it still smells. Any thoughts?
