What would you all do for my ICH problem?

[tannersmith200]

Problem: My regal tang (1" long) is covered with white spots. My Koran Angel (2" long) is showing signs of white spots (not near as many). Almost positive I have ICH. What is the best solution to my problem? I have a 10 gallon tank for my feeder shrimp but I have none designated for a QT tank eventhough should. Any advice?Symptoms: White spots, rubbing LR frequently. Eating just fine.
Diet: Flake food with added garlic, agar, algae strips.
Duration of symptoms: I bought regal tang about a month ago from SWF.com and had 1 white spot. I have not had an ICH problem before. The Koran Angel has shown mild symptoms since yesterday.
Species/Stock List:
Fishes -Panther grouper (2" long), Convict Damsel (1 1/2" long), Blue Damsel (1" long), two false percula clowns (both 1" long), Regal Tang (1" long), and Koran Angel (1" long)
Inverts - Sally Lite Foot, various hermits (10-12), Astrea Snails (10), and two orange tree sponges
55 Gallon FOWLR - 65 lbs LR, 2 - 3" live sand base. Tank system has been running for 3 months. I am expanding to a 300 gallon FOWLR tank in the near future

Set up the 10 gallon for some of the rock and the inverts. Put the rest of the rock into a storage container with saltwater from the display, a heater (if needed), and a powerhead. Perform hyposalinity on the display. There are instructions in the top FAQ thread.
