My 55 gallon brackish is at a salinity of 1.010 right now with MARINE SALT. One of my puffers has an open ulcer-type wound and I have previously treated the tank with fungus cure. (Here's the whole disease story: http://www.myfishtank.net/forum/disease-forum/50921-normal-reaction.html)

I'm wondering if it would do any good to add some aquarium salt (the API kind...FW aquarium salt) as a tonic to help him heal a little. I know chemically marine salt and freshwater aquarium salt are different...but does the marine salt have the same tonic-type qualities of the aquarium salt?
