This method is not practical, it sounds good in theory. The biggest pitfall
with this method is that you have to first catch the fish from the tank, and
catching them is not easy unless you have a bare bottom tank, no coral, no
landscaping.

Putting vcoper in a marine fish tank is bad to do. A quick and simple
dip in RODI water that is preferablly temp and PH matched tothe tanks
water is a very effective way to fix an ICH problem. Use a separate
tank or container to use for the dip of about 1 or 2 minutes. I let em
in for as long as possible or up till the fish starts to stress out. I
also like to keep the tank free of any fish for a couple of weeks as
well after the infected fish are removed in additon to healthy fish as
without a host the ich parasite will die. It pays to have a basic bare
hospital or quarantine tank with fresh or salt water fish.

Odds are you may have problems if you ever decide to have any inverts
with the copper that is in any live rock or silicone seals, but if its
a fish only tank its not a problem other than the usual staining of
the silicone seals. When you dip a marine fish with ICH in freshwater
you can literally see the parasites
