MI is a real pain. First, make sure it is MI. second, Without doing the copper or Hypo, try feeding garlic. Kent makes Garlic Xtreme which helps with the immune system which you'll want to soak your food in it for about 15-20 minutes prior to feeding. I use this everyday just as a supplement. You can also add Metronidazole to their food but combine it with Focus. Turn your temp up but don't cook the corals. Turn lights off except during feedings (less stress) and feed heavy. Keep the fish strong and hopefully you can beat the parasite. Try doing some research as well so you understand the different stages. There is one product that is reef safe called Kich Ich but it is hit or miss really. If you try it, double your dose but there are truly no guarantees with it. If you start losing the battle (like if the fish stop eating), I would definately recommend a quarantine tank and treat Hypo or copper (not both together). Good luck.
