These are the only reasons to use salt in a freshwater aquarium that I know of.

1. Treating any illness or disease or parasite that can be cured by salt treatment.
2. Preventing nitrite poisoning

Note that for each of the above it is only for a short term use, and not for everyday use.

Basically you don't need salt for everyday use.

Since you have tetras I will also recommend the no salt route.

From what I have read, SA tetras come from areas where there is so little salt as to be none in their water (less than is measurable in ppm). Salt can be quite toxic to them, so I avoid it at all costs.

I'd just leave the salt out, until such time as you absolutely have to use it. Salt will stress any kind of freshwater fish to some extent. Some just handle it better than others. And that's just talking about a short 7 to 10 day treatment.

A big +1 to all of the above.

I run no salt in my FW tanks.

I pretty much agree that salt is not generally needed, except for helping cure certain ailments, or for aiding in getting rid of ich. One exception though would be African Cichlids. Many people use salt or a salt mixture to help buffer otherwise softer water.

There is no reason to use salt. And you don't want your fish to become immune to salt for when you may need to use it. Plants don't appreciate salt, either.

I use salt only if I see a wound. I once had an angelfish that had a big bubble of some kind sticking out of it's gill. It was there for months no matter what I did to treat it. I added salt and the darned bubble was gone 3 days later. Still have no idea what it was.
