Refractometer

[aldog51]

I just received my new refractometer and my salinity read 1.025 and my plastic hydrometer used to read 1.023, is this a safe level for my reef setup with about 9 fish ( 1 Yellow Tang, 3 Damsels, 1 ClownFish, 2 dart fish, 1 Coral beauty, 1 sand sifter)

Should be fine, IMHO. That's actually just about the SG of natural seawater.

You now have an instrument that will read Salinity. You should stop looking at Specific Gravity ahn use the Salinity scale. Shoot for 35ppt.
