, not sure what to do. I have upgraded my 55 gallon reef tank to a 120 now. It has been running for about 4 months now with out a problem. I noticed ICK starting about a week ago. I currenly have a porcupine puffer, yellow tang, hippo tang, some clowns, and some damzels. I have 3 anemones, star fish, and some mushrooms. Any suggestions. I have been using Kent Garlic additive to thier food for about a week. but now it seems to be getting worse. I think my protien skimmers is under powered right now, but will that make a difference? Trying to get a good skimmer, but not sure which one i should get. Any help would be greatly appreaciated. Thanks, Carl.
