I use a Hydrometer (instant ocean)

When I was using a refracto with my old setup, I compared the results to the hydro with each test, and they were always bang on for me.

Used Hydrometer for years always seems okay until one day mixing salt using the usual amounts and was low, checked on the display and low there as well. Did a comparison with a refractometer and numbers all where I expected, checked the hydrometer and was off ~0.006

Not to say a refractometer will go out of cal, just have more confidence in it so been using one since. Easy to use, easy to clean.

Using the same hydrometer I've had for 10 years. Checked it once against a refractometer, it was bang on.

I was using the instant ocean hydrometer when I started out, until like the others I found out how off it was and switched to a refractometer.

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

I started out with a hydrometer and it was always off, it wouldn't read the same thing twice in the space of 5 minutes so I switched to a refractometer...

I like my refractometer, I had little faith in my hydrometer being right as I was always getting bubbles in it. I just don't have the patience to flick them all out

I think someone needs to update this post.

Shut up!! Yes, my trusty hydrometer finally gave up, and threw y salinity off (1.030). I've since bought a refractometer

Refractometer = accuracy.
