You will find a difference of opinion among aquarists on using salt, which is fine, provided each opinion recognizes the science and the risks. I will never put salt in my tanks, not even as a treatment because of the side effects. If you want the scientific facts, read this:
Yes, I wrote it, but the science is not in doubt and it comes from the references cited.
Pop, the Jensen data can work, but the context is critical. Marine salt is not "salt" as the so-called "aquarium salt" or table salt [this is explained in my article]. Epsom salt is pure magnesium sulfate, which is nothing remotely close to "salt." And baking soda (sodium bicarbonate) is one thing in hard water but a very different thing in soft water. And the concluding info about how this combo works for hard water fish is the key. Plus we must assume there is going to be medium hard or harder water as the source water, and this also plays into the equation.
Using that combo in a soft water tank with soft water fish would not be healthy for the fish.
