Tony, hyposalinity works. I did hyposalinity on every fish I bought for my tank, going back over 18 months. Most showed ich the first few days in QT, then never again. Then I had to screw up and introduce it to the tank, so I'm doing hypo all over again.
The key is maintaining accurate salinity levels. Too low is harmful to the fish, too high won't be effective at killing ich. I target 1.009, and never let salinity climb higher than 1.010 for the duration. With such a narrow window, make sure you are using something that is dead-on accurate to measure salinity. A swing arm hydrometer, or a poorly calibrated refractometer could be problematic.
