Good calibration fluid for salinity
This calibration fluid by reagents matches with Bulk Reef Supply, Refracto Juice, Calibration fluid for salinity. Faster shipping than BRSโs.

Defective solution!
Warning!! This standard was off by .05! Solution tested at .021 instead of .026. Thank god we had other solutions to verify our readings. Could have killed a ton of corals fast!

Does what it needs to do
So I used this calibrate my refractometer for my reef tank. turn out i was a bit high and had to adjust the calibration screw to get the correct reading. 5 stars from me for ease of use and price.

Great for calibrating refractometers and digital salimeters.
Bottle was full to top which was nice. This will last me at least a year.

donโt buy
It is off by a couple of points. The salinity of the fluid is supposed to be 1.0264 but it is way lower around 1.023. It is a waste of money.
