    I used it to calibrate, now not sure if I trust it

    I used this on my refractometer and adjusted it by 0.001SG. Seeing the other recent review, now I'm not sure if I cant trust it.

    Do Not Use, Not Correct Index

    Posted by Earl on Sep 20th 2018

    As mentioned, I had always used RO/DI water to calibrate and never had a problem and matched what others got. So I bought this to make sure I was doing it correctly. After I calibrated both of my refractometers they both showed RO/DI water as -2 points below zero. I knew something was wrong at that point. I ended up buying a digital refractometer and sure enough, this stuff is way off as seen in the photo below. It's a total waste of money and will have you running your salt levels 2 points higher than you want. All I can guess is that some has evaporated and as a result, WRONG. <br><br>

    Handy to have

    I always calabrated my refractor with RO/DI water. Then I was told to use this. My refractor was off by a couple of points. What I thought 1.025 was only 1.020. Now my salt level is backup where it should be.
