Just started my first reef tank. LOVE LOVE LOVE it! Its been up an running for about 8 weeks now. Everything has gone great. Cycle went well fish and inverts doing great. I bought a green bubble tip anemone about 2 weeks ago. He was doing fantastic until he met my powerhead. Theres on oh crap moment. So I've had to do a major water change and came home from work today and my 2 tangs, Purple tang & Blue Hippo tang are covered in ICH. I have been feeding them with extreme garlic for about a week now. Have read this can help. Any other suggestions? Don't want to treat with copper as I have a few corals going.
