It seems like every store I go to has a coral section with at least one fish in it. Those strong chemicals wont kill the ich? Is the only way to kill it to let it dry out/ have no host?
No chemicals (that we currently know about) will kill Ich during its encysted life cycle stage (tomite/tomont) without killing the fish/coral/etc along with it. So you either have to let it dry out which is obviously not an option with coral, or let the life cycle complete without a fish around, thus killing the parasites when they are released (Theronts).
