I went through hell with Ich last year in my 90gal. 45 day fallow, reintroduced all fish and had another ich breakout within a day. Did another 45 day fallow, returned the fish, and ich again...
At this point, I honestly believe Ich management is the best way to go. Even with perfect quarantine practice, people are still getting ich. I just try to keep the stress low with consistent water parameters, try to keep my hands out of the tank, and borderline overfeed with selcron and vitachem daily. I also have a UV steralizer rated for a 200gal tank on my 90. Not sure if it actually helps with the ich at all, but I know for sure I have it in my tank and havent seen a spot in over 6 months. I wish you the best of luck.
