Consider where brackish fish occur in the wild: Where FW meets SW. That means it is going to be a mix of FW and SW, requiring marine salt.
You need the buffering elements and other minerals and elements (my marine salt tells me there are over 70 present in the salt as well as sodium and chloride). Fish pull a anumber of elements out of the water in preference to food (such as calcium).
