Testing on brachish water - fresh or marine...?

[flipz]

Should I be testing brackish water (1.012-1.015 salinity) as freshwater, or salt water when testing for ammonia and nitrate? Thanks!

I would test fresh. I will be testing fresh when my BW tank gets set up.

You want to test SW, because you're supposed to be using marine salt, not aquarium salt. FW tests will not work over a specific gravity of 1.005.
