You should be seeing signs that the ulcer is healing by now (getting
white-ish around the edges, maybe a "film" of new skin?) Photos I've seen
indicate perhaps 25-50% healing in 2 weeks, depending on the initial size.
Everything I've read says to return the fish to his "home" after the final
treatment: usually, "home" has the best water quality, and the fish likes to
be back in its normal surroundings with its friends, so there's a
psychological benefit, also. (For those that may be reading this and
thinking that I'm anthropomorphizing, I'm not: koi are community fish and
sulk if left alone - they like company.) Of course, water quality should be
top notch (if it's your pond, I'm not worried, but if it's someone else's
pond, it needs to be emphasized). Me? I'd get some Koizyme (formerly
Lymnozyme) in there, too: you can't have too much help.

Good luck!

All fish in the pond are looking good too, I am wondering if I can relax
yet?

Can anyone tell me how long it might take an ucler the size of a quarter
to
heal up? Should one wait till it is completely healed before returning
fish
to pond with its buddies? ~ jan
