Just thought I’d share my most important reef purchase I’ve ever made. This thing is magic. If you don’t have one, you need it! Refractometers are a thing of the past. Thanks @Hanna Instruments for this masterpiece.
I like to tell people that by the time you check your salinity with a refractometer, I could have checked mine, yours, and the neighbors!
