kick-ich is very effective on ich and totally reef safe
It has been my policy never to treat a display tank with meds unless every other option has been expended first. Meds like Kick-ich are touted as being reefsafe, but in my experience they are very hit-or-miss.
As far as all the herbal remedies (ie using garlic guard, etc), it will not get rid of ich. Garlic is not proven to boost the immune system of fish. What it has been shown to do is entice fish into eating your prepared foods and thus eat properly (when a fish is stressed or sick, it tends to stop eating). This in turns helps to improve its immune system and possibly build an immunity to ich. This does not get rid of ich, it only suppresses it (the fish will still carry the ich, just not show symptoms). The ich will go into a dormant phase. Because the ich is still there, as soon as you introduce any new fish, or cause your current fish to be stressed, their weakened immune systems will no longer be able to supress the ich and cause another ich outbreak.
IMO, the only tried and true method to erradicate ich from a fish-only or reef system is to remove all the fish from that system and QT them for a period of 4-6 weeks using either a hyposalinity treatment as stated above, or using copper. Either way, the display tank must remain fallow for 4-6 weeks in order to completely erradicate any ich in that tank (ich needs a fish host). Once you have removed ich from your fish and your display tank, you must take care to QT any future fish in the same fashion (QTing for 4-6 weeks in a hypo or copper solution), or else you will have done all the previous work for nothing.
I know it sounds like alot of work, but keeping and maintaining fish/corals is not about taking the easy way out, or using quick cures. If you take waterfaller1's and my advice, you will be alot better off in a couple months and your fish will thank you
