I have a 90 gallon reef system, tons of coral and inverts. I have 6 fish, 4 of which have very bad ich. Ich infected: Copperband Butterfly, Yellow Tang, Hippo Tang, Flame Angel. They have ich really bad, and I have no qt tank to put them in to treat. I'd hate to lose any of them, especially the CBB, he has the biggest personality out of them all, and he is eating, which I've heard is hard to get. All of them are still eating, and have had it for about a week. What should I do!? I turned off my skimmer, and uv sterilizer. I run 2 box filters, and have no sump/refugium. Thanks, please reply!!!
