I made the mistake of using a hydrometer until my corals melted from high salinity. I switched to using this afterwards and my salinity has been perfect ever since. The calibration is simple and it did take a few minor adjustments but since it settled in it is dead on when I check every week before checking my salt water.

I was a little hesitant at first seeing as it is more expensive then the hydrometer option, however I a glad I purchased this product as it is high quality, easy to use, and gives clear readings.

Well built and for the price, unbeatable. I managed to get this on sale for under 20 here at BRS during their sale. Even at full price, this is a lot better and more accurate than using a hydrometer and the price difference isn't even that great. Save yourselves the trouble and use this.

Been using a hydrometer for the past 5 years and finally decided to purchase one of these. Very well built and included case makes for easy and safe storage. Only problem I have is the calibration fluid was not included in my package, but for the price, still a great purchase.

This Refractometer is well built and includes calibration fluid so you know you are right where you want to be. Much better than a hydrometer and easier to use. Three small drops on the lense and look thru the tube towards light.

Everything is as advertised and very very high quality. My only complaint is it was delivered 3 days after the predicted delivery date.

I just started in the salt water hobby at the beginning of October and since then I had used the swing arm hydrometer figuring it had to be close enough. Well I picked up this refractometer during BRS's doorbuster sale and all I have to say is why didnt I get one of these to begin with? Super easy to calibrate and use and it gives a peace of mind that no hydromter can ever give. If you are just starting out, or have been in the hobby for years and never got one, I recommend that you do yourself the favor and pick this up and never play the swing arm guessing game again
