what do people use - just distilled water and adjust to 0?
hughjamton,
Please tell us more. I had no perception of a refractometer being used for a fish tank!
I could understand, perhaps a hydrometer, or a pH meter, but a refactometer would seem to serve no purpose with a fish tank.

I think olive oil would do.

Tested three different brands of olive oil in the past,new bottles, and each one different RI, so now need to test with a fluid/oil that is accurate, to find out which one of the olive oils is the correct one to use for setting the refractometer......lol.
