To my knowledge there is not set point of what is brackish water. It seems that it is commonly accepted that brackish is inbetween a full fresh setup, and a full marine setup. To be sure, you need to get a hydrometer to read the salinity of the water. Adding Aquarium Salt does not make a tank brackish. Brackish conditions are only created useing marine salt.

Well, I'm not going to repeat the whole article. Its a good read and should really help you on your way.

A common number often thrown out is 1.008. However, most swing hydrometers don't start until 1.010 or so (at least on the graduated scale). You kinda have to eyeball the needle... I keep my fiddler crab tank at about 1.004-8.

Keeping salt in a freshwater tank does your fish no good. If they are freshwater fish, they should be in freshwater. Saltwater fish in saltwater. Brackish fish in brackish water.

Is the stocking list in your signature all in one tank? If so, that's not going to be a terribly happy tank long term.
