What species of everything are you keeping?

Doesn't sound like you even have any brackish fish...

What are you measuring, isn't hydromter in Specific Gravity not ppm?

Hydrometers often show both specific gravity and ppt (parts per thousand).
Look at a plastic instant ocean hydrometer, it will say "ppt salinity" on the opposite side of the specific gravity.

Parts per million I have no idea about...

I think OP is confused about several aspects of his question
Or maybe I'm not understanding something.
