Hmm.. I donnu I haven't lost a fish from ICH in 7-8 years, when I did It was my first tank, and I'm sure my water parameters were way out of line to. That's not to say that I haven't had ICH present in my systems. We all can/do, but I've never found it to be a matter of concern or ever resulted in the death of a fish without some serious outside factors that would have killed the fish regardless of having ICH (ie water parameters or stress from other fish). It's like Red bugs on acros. If everything else is solid they really shouldn't be a cause for alarm. Setting up another tank for 8 weeks, then moving it over eh, sure you may kill any chance of getting it from that fish but what about that coral you added or that piece of rock? It can come from almost anything you drop in your tank if you have unlucky timing. It's just not worth the added risk/stress/and hassle to move your fish from system to system for me. As well the issues you have now trying to maintain two systems as you can't just QT it in a tank run off water from a split sump or you risk commentating the whole system. Unless I bought some crazy super delicate really expensive angel I don't think I would ever bother QT'n a fish for ICH again.
