Quit debating on whether or not to go to an electronic meter. This little guy takes the guess work out and lets you get on with your reefing! So much easier than titrators - its easily worth the small investment price.
Best Product for testing alkalinity By Kenneth on 11/9/13

THE HANNA CHECKER FOR ALKALINITY is one of the best checkers. This tool takes the guess work out of testing the water. I can wait for them to come out with a test checker for each water parameter. I have to admit I am lazy when it comes to doing something that i hate. I don't have this problem with the Hanna checker it fun, easy to use and no more guess what color the sample matches.

The hanna checker is awesome. In a few simple steps, you know exactly what your alkalinity is.

Reliable, spot on numbers and easy to use. Better than tritation test.
very fast and high precision By Joe on 7/20/13

This Hanna checker allows you to measure alkalinity very quickly and easily. It can be made even easier/quicker if you have a 1 mL pipettor. The measurements are very reproducible (high precision), but accuracy is harder to determine. For example, I made up some Red Sea Pro salt mix at 1.025 SG and measured alk with Hanna checker and the Red Sea Pro Alk kit. The results from two measurements were:
Hanna: 4.50 and 4.52 meq/L
Red Sea: 4.15 and 4.15 meq/L
These are significant differences, but the Hanna Check is closer to the expected value of ~4.4-4.53 meq/L. Of course, there is no guessing the end titration point with the Checker either. I've retired the Red Sea kit.
Very Accurate Tester By Kash on 7/15/13

I used to use the Salifert Alkalinity test & found it hard to read the color change accurately but ever since i switched to the hanna alkalinity tester it has become very easy to precisely determine the value. The test does take around the same time to complete as the Salifert kit but there is no comparison with the Hanna digital readout. Great Product!

No more worrying about test results. I am now confidant or my tank's alk levels. I like this meter even better than the phosphate checker, which I also highly recommend.

Digital is the way to go. One reagent to add and you get a very accurate result. Tested twice in a row to see if the number would change even by 1ppm but it was identical. Wish you could change it to dkh vs ppm. Makes me do one more conversion.

No More Confusing Colors By Thomas on 3/18/13

I love this thing. I have been using the Hanna Alk checker for five months now and I still love it. My old Alk test was hard to delineate between the colors. With the digital read out there are no more questions of the results. The process is easy and fast. It is well worth the investment.

It does not get any easier to check alkalinity. No more guessing what the color is. I would recommend to any reefer.

This tester is super easy to use and results are fast and accurate. I have always had a hard time trying to compare colors on other test kits, the Hanna Checkers take all of the guesswork out of it and give you an actual number.
hands down the best alk tester on market By BK on 2/6/13
BK would recommend this product to a friend
Love this test kit for its simplicity and digital readout. You must do a simple calculation to get DKH reading (multiply X 0.056) and then you are set. Used red sea alk before but always had some gray areas with the titration.

I have both the Hanna Alkalinity and Phosphate checkers. Both are incredibly easy to use and the results are very accurate. I would recommend them to anyone looking for better test results. The initial investment for the checker is well worth it as the refill kits are cheaper than buying test kits repeatedly.

It works just like its suppose to. It's very easy to use and is all organized in a waterproof case. Hope to see more quality products like this one for the aquarium hobby.
