If the ich is on the fish, it's probably in your main tank already.
DO NOT USE COPPER!! Copper will kill any and all invertebrates in your tank, and will leach into your rock and sand and won't come out!
You really need to set up a hospital tank and move all of your fish over to it.
Raise the temp in your hospital tank to around 85% or so, and drop salinity to 1.018 to kill off the ich. You can also do a freshwater dip of your fish to remove any attached ich-do a search on "marine ich" to see more on what to do.
You'll need to leave the fish in the hospital tank for around 6 weeks, to kill off all the ich in your display tank. If you raise the temp in your display tank to around 85 also, it will speed up the life cycle of the ich & kill them off quicker.
HTH!
