Does hyposalinity really work for ich?

Sometime copper is the only way to save fish but I would use it as a last resort and if in case of velvet. Velvet kill so fast that even copper need to be started early in the disease.

You can't treat marine velvet with hyposalinity, but you can treat MV by doing repeated freshwater dips. I have been successful with this method. It does take quite a bit of work though because the infected fish has to be placed into a "sterilized" QT afterward. I always use display tank water in a QT, of course that doesn't work if the infected fish was already in the display! Sterilized meaning a QT that isn't infected with MV or a thorough disinfecting of the QT so as not to reintroduce the fish to the parasitic dinoflagellate. Yes, MV is an algae.

Here is a great article on Marine Velvet including a description of how to use freshwater dips for treatment:
