Don't be surprised if you see a bigger outbreak of ick in about 3-7 days. Usually when you see the fish clear up it's because the ick has dropped off to reproduce. You may want to plan on a QT tank just in case...
I tried Garlic Extreme before, it did not work for me. The only thing that worked for me was to remove all fish and give them the hypo treatment for 6 weeks. This kills all the parasites on the fish, and leaving the tank without fish for 6 weeks kills off all the parasites in the tank.
I did have a case where the fish became immune to the ick (without treatment), but I fear the tank may have a "subclinical" case of it (so that a newly added fish may come down with a full blown case of ick).
Let us know if it comes back, or if your ick free a month from now.
Good Luck, I hope your fish make it! Ick sure is a nasty bug...
