Refractometer calibration solution

Am I missing something here? I've always calibrated to zero with RO water.

Okayyyy, so after a little searching apparently zeroing with RO can miscalibrate your reading. Not sure by how much considering I've never had a problem.

That being said I will do the loop, find some of this solution and get back to you guys as to how far off the reading is from zero.

that is what I always did , until I was reading up on it . Ended up grabbing some from wais and it was out a fair bit , but like you never noticed any issues prior to using the fluid . And have also not had any issues since switching the calibration fluid lol

I always calibrate my refractometer with Distilled Water until I almost killed all my SPS as I can't figure what's wrong with my tank as all parameters seems to be right. After some googling I came across this blog:

So I decided to buy a Pinpoint refractometer calibration fluid. I was shocked more than my corals about what I found out. I was running my tank salinity @ 1.030 for the longest time.

I then check other forums regarding this and there are lots of threads with this discussion.
