Ich in reef tank

[Tonii]

Hi guys,
I've had my reef tank for a few months now but last month I had an ich outbreak. I lost two clowns and I took out the remaining two fishes out of the tank into a quarantine tank. All I have left in the main tank is a couple of corals and a clean up crew along with a cleaner shrimp. My question is how long do I have to wait for the ich to completely die in the tank. I have been reading online that it could take from 48 hours to 2 months but most of the threads are from early to mid 2000s. Is that still the consensus or what do you guys think?

Thanks in advance...

The current belief is 72-76 days for the fallow period.
