I use a product called Greenex to combat stress related ich. Usually when I first introduce new fish. It is reef safe however it will discolor the silicone. Administered as directed, it may take a couple of weeks and can be removed with carbon.

Also have a cleaner shrimp in the tank. Not sure if it helps but have talked to others who beleive that cleaner shrimp help to keep ich under control and may even assist in irraticating it.

Hope this helps. Good luck.
