Okay... Just went to Petco, checked out their API Freshwater and Saltwater Ammonia Test kits. In it are two color charts, one for fresh and one for salt water. Salt water is 0 ammonia at the same color 0.25 is for fresh.
Think all is good in the brackish tank after all. Water is at about 1.012 give or take a point or two. :-)
