You've already gotten a lot of advice. But I will reinforce the statements that you must remove all of the fish from the display tank to get rid of the ick. Yes, it sucks...tearing apart the tank to catch the fish is not fun, trust me...I had to do it myself. You don't have much time since once ick is noticeable it's not long before the fish start to die. You can try to train the fish to feed from a net and then sweep them up once they get comfortable feeding from the inside of the net, but you may not have time before they start to die, and you won't get them all. You can also google some ideas for making a trap out of a plastic water bottle...you might get a few that way. Siphoning off the water and removing the reef/rock is really your only option.
Ozone and U/V are not 100% effective. You need to get all of the fish out of the tank and then keep them in quarantine for the entire 76 days. Yes, your fish in quarantine will look great well before the end of the quarantine period, but it's not the fish you are worried about, it's the ick cysts in the display tank that need to die out. I once cut my quarantine short by a week or so and within a few month the ick was back. After finally repeating the entire ordeal I've been ick-free for a very long time. In the future, quarantine ALL new fish purchases for a month before you put them in the display tank.
