Works well
Good solution for testing my tanks

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

update. LFS SG was off. not as bad as i thought.
tested with another solution as well. both are around 1.026.

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.

Bad batch. Low salinity.
Poor quality and batch control. As others have mentioned, mine also came off. It's at 30ppt or 1.023. I checked against 1 other calibration solution, 2 refractometers including a Veegee as well as a freshly calibrated Hanna handheld conductivity salinity sensor, and verified with 2 separate calibration solutions. If a calibration standard is off by more than 10%, it totally defeats the purpose.

Quality
They work perfectly

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

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.
