Sure. Instead of treating your tank with the medicine, grab a heater and crank it to 87-88F. It will stop ich in it's track. Leave it there for 2 weeks or so, and you should be good to go.
If for some reason, you don't want to do this, I'm fairly positive that the Jungle product will be fine with your water. It will take a lot longer to treat however, so grab extra.
Heat is the way to go. Trust me.
