thanks

Are you sure it's ich?
ich-x doesn't work on ich. You might want to run do some water change and run some carbon to get the med out of your water.
For fraction of the cost of a purple tang, you can set up a quarantine system. let me know if you want to do that and I can tell you what you need.
Or you can leave it as it is. Your fish may or may not survive.

Tank transfer method is the easiest, copper is not too bad depending on what other fish you have. hyposalinity is the only other method that works but is by far the hardest of the 3 effective methods.

Last year I tore down my reef to get my fish out, it sucked but they are back in and things are going well again. It wasn't fun but it had to be done.

There is a fourth treatment, chloroquine phosphate, that has been proven to effectively treat ich. The problem is to find the real chloroquine phosphate.
New life spectrum ick shield *powder* has ingredient closely relates to chloroquine phosphate and proves to work as well.
my recommended treatment for ich in the order of effectiveness and less stress on fish is:
1. tank transfer method
2. chloroquine phosphate
3. hypo
4. copper
