Tank with Ick

So recently, I've noticed white spots near the head and tail of my royal gramma and the head of my bicolor blenny. I've struggled with ick in the past and have overcome it with surprisingly great success. My problem is that, with all of the live rock in my 60 gallon tank, there is no possible way for me to remove every fish and put them in the QT without removing all the live rock and corals.



I guess my question is, is there anything to use to treat ick where I can leave the fish, invertebrates, live sand, live rock and corals in my tank? I have about 10 fish in my 60 gallon and honestly, would be okay with losing a few of them. (except my yellow tang, he better live)



Is there something out there that can be used to treat ick that wont harm any inverts, corals, live rock or live sand? If so, Pleeeease help! I'm very worried for my fish!



Thanks!!!
