I have been Reefing for over 15 years and have been using the old fashion hydrometers. After using a Refractometer I would never go back. Readings are so fast and there is no need to shut off mixing pumps to get a good reading. .

Only "complaint" is that it is much easier to read pointed at a bright light, so doing evening maintenance requires some squinting.

After years of messing around with those crappy hydrometers I finally went with this refractometer. I don't know why i was waiting. This thing is so much easier to use while being way more accurate. Incredible quality for the price. Get it today.

I picked one of these up recently, and was surprised with the quality of the Refractometer for the price! It arrived quicker than I expected, came with a sturdy hard plastic case that everything fits into perfectly. This being my first purchase from BRS I'm very impressed and will be shopping here more in the future!

I've been using an float type hydrometer but purchases a refractometer with calibration fluid and love it. BRS had it and other supplies here in three days!

Bought this after getting conflicting numbers from my IO hydrometer. This is easy to use and calibrate. I use it often as I'm starting a tank and have yet to even calibrate it. Takes a few seconds to measure and then a quick rinse w/ RODI and I'm done!

Very easy to use and calibrate and accurate results. Used to use a swing arm hydrometer but after I started investing in corals I wanted something I could trust a little more and for the price the BRS refractometer can not be beat! I have had it now for at least 8 months with no issues. The most it was ever off was .001 which was fixed with recalibrating with the including recalibration fluid

This is a great tool for the home aquarium. Was using a small needle type meter and found it was a solid 3 to 4 points off. Tested my tank with this little beauty and I was right at 1.026. Glad I didn't add more salt. This tool os so easy to use my wife is willing to check the salinity as it only takes a second.

Hydrometer was way off By Anita on 3/2/2013
Anita would recommend this product to a friend
I just received my refractometer and calibrated to the fluid. Tested my aquarium and about fell over! The salinity was reading 1.015! According to my swing-arm hydrometer, it was 1.023. I only have one coral -a very forgiving star polyp - and my fish have been fine. So I obviously need to bring that salinity up. That POS hydrometer is going in the garbage!

Well constructed and simple to use. Just make sure you calibrate with the provided solution - there is a large reminder sticker on the box. So far, appears to work exactly as intended.

I've been reefing for 4 years and always used a cheap plastic hydrometer. I haven't seen great growth in any livestock. Decided to dive into this refractometer. Glad I did. My plastic meter read 1.025. Tried the refractometer and it read 1.030! Made the adjustment and everything is thriving. A must purchase for little cost!

You can't beat the price and the accuracy of this refractometer. The calibration fluid that is included is an added bonus. The lines are large and easy to read.
Not sure By Testor on 1/24/2013
Testor wouldn't recommend this product to a friend
Printed instructions with ATC unit say to calibrate with RO/DI water. When I do so, the readings on the ATC match the readings I get on a digital Hanna refractometer. However when I test the calibration fluid that came with this unit, it's reading is 1.028.
So do I assume the calibration fluid is off, or trust it, and recalibrate the optical ATC unit, and assume the digital Hanna is off.
I know BRS site says to use calibration fluid to calibrate.

Forget your little floaty tool. This couldn't be easier to use or more exact. Every reefer needs one of these!
