Aquarium salt is effective against both parasites and bacteria. A salt dip is a safer alternative to adding salt right into his water. I personally believe the salt dips did wonders for my fish when they had gill flukes.
Use a spare bucket or container, and do 3tsp Aquarium salt to 1 gallon of water. Leave him in there about 30 minutes, keep an eye on him, if he starts tilting sideways and losing his buoyancy he needs to come out ( I never had that happen though.)
When I was doing daily water changes I did the salt dip every day, while I cleaned their QT tanks.
Edit: Make sure all of the salt is dissolved before you put him in (you might have to stir it up). Make sure you add water conditioner into the salt dip water, make sure its the right temp, etc. Also, acclimate him slowly. I would get him in a cup from his tank, add a bit of the salt dip water into the cup, let him acclimate to that, and then just pour him into the salt dip bucket. When you are done get him in a cup again, and pour him back into his tank.
