yeah if a refractometer is calibrated it's bang on. I find a refractometer much faster and I don't bruise my finger flicking bubbles off a swing needle.

Also a refractometer only needs 2 drops of fluid. Great when you're testing the salinity of creatures you're acclimating vs. tank water. It's kinda hard to submerge a hydrometer fully in a bag of snails only filled 1/4 full with water :P
