Great product
Really good product come fast and accurate my reflectometer was in 1.024 but thank to this product i fix it again (1.026) really easy to use

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.

Not Great!
I bought this item to help calibrate my refractometer and instead, it gave me an inaccurate reading for my salinity. I followed the direction exactly to the "T". With the refractometer that I bought its directions told me to calibrate with distilled water and I would get the right salinity range for my reef tank. I also ensured my refractometer was calibrated amongst other fellow hobbyists and local fish stores around my area by testing my salinity for the same reading. I must have received a bad batch of calibration fluid, but for me to go through all that trouble to second guess my reading with my refractometer after using this fluid gives me less confidence to buy this item again.

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.

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

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

Works as expected
Works great. Calibrated my refractor. More accurate than distilled water.

Calibration liquid
Great calibrated my refractometre so I know my salinity is correct was delivered very fast

don’t 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.

DO NOT BUY
not 1.026 its way to low. do not buy!!!
