In regards to this, my concern is why do I care? Since my tank has seen 8 dots of ich in as many months, isn't your suggestion a lotof work for not a lot of return? I know, the level of return is relative, but really, I wouldn't empty my tank of fish for 6 weeks while soaking them in fresh water. That would be more stress than they could ever experience in the main tank. JMO.
