With that said, there are only two true ways to battle ich. Copper based medication or hyposalinity. That said, neither of these can be done in the display tank and need a hospital set up.
If the inverts were removed, I don't see any reason why hypo couldn't be done in the display.
copper in a separate tank would effect a faster cure, but using copper comes with it's own bag of concerns and risks and you still have to leave the display fallow for 8+ weeks anyway, so.....
If it were me considering there are is coral and not a lot of inverts, I would try hypo in the display as the least stressful treatment.
In a hospital tank you have to catch them, put them in a more crowded tank, subject them to copper treatments, all could potentially lead to a stress induced disaster.
Why go through all that when you can treat in the display?
