After YEARS of having my wife make sure to check the color for me, well no more!!! This thing is accurate!
Great Product By Chris on 3/23/2015

Fast and easy to use. If you only buy one Hanna checker, this is the one to own because it is clearly easier and faster to use than a traditional titration method.
Easy and fast way to test for alk By jent on 3/22/2015

The tests are reproducible, and much easier to use than the other drip based methods I have used. I have always struggled to have reproducible results, but with this kit I absolutely can!
The only tester you need for alkalinity By Nick on 3/22/2015
Nick would recommend this product to a friend
It is extremely straightforward and very simple to use. I get very accurate test results and do t have to fool around with liquid test kits anymore. The only thing you have to do is convert the result from parts per million to DkH.

I picked this up on NOVEMBER 22, 2014 and have been using it since. I will never go back to my old ALK test again!
Wasn't always reliable By Luke on 3/10/2015

I bought the Hana Alkalinity tester so I would never have to use a titration test again. Sadly, this wasn't the case.
The Hana checker came in a nice plastic box with everything I needed to begin testing. I tested the water on my tank as well as various other tanks and I always got a different result when compared to saliferts tesk kit. Sometimes these differences were small so I payed no mind, but most of the time they were way off, like 3-5 degrees or so.
The hanna checker measures in ppm's not DKH so you do have to do some converting when you use it.

Love this tester By Christopher on 2/11/2015

This test has got to be the absolute easiest of them all. Fast readings and its great to have a pin point reading rather then a whole number. Good for measuring alk usage and dosing.

I tested my alkalinity at home with the hanna checker and then had my local fish store test my water with their hanna checker and it was off by like 15ppm ,found that kinda weird but anyways they work great and easy to use

Easiest and quickest alkalinity test available By JD3 on 1/12/2015

This test is so easy to do. Its alot quicker than going drop by drop like on some other test kits and what better way to see the results than with a digital display.
worth every cent! By CaliOCorals on 1/8/2015
CaliOCorals would recommend this product to a friend
Only downfall is you need to do some math to get dkh. 1ppm=0.056dkh.
So example is device displays 145ppm (145ppm x 0.056 = 8.12dkh)

Works Like a Charm By ncoble4 on 12/15/2014
ncoble4 would recommend this product to a friend
This test kit is easy to use and works as advertised. The only reason it does not get 5 stars is that the bottle of reagent does not seal properly after it is opened for the first time. I found this out the hard way by screwing the cap back on, placing the bottle back in the plastic box and putting it on the shelf. The next day when I went to test, the reagent had all leaked out in the box so I had to order more. :(
Now I keep the reagent upright on the shelf separate from the box.

I have the Hanna Phosphate meter and recently purchased the alkalinity meter. This is so simple to use, and I like the numeric readout. Well made and takes the guess-work out of water testing. Now if they would just make one for Nitrate.

I bought this along with the Calcium and Phosphate checker. No more wasting time guessing, these gadgets makes it fast, easy and accurate when getting your tank parameters in order.

This testing kit came to me highly recommended. I'm glad I bought one at a very competitive price as a BRS doorbuster. The testing process is quick and very easy and seemingly accurate. My only complaint is that Hanna doesn't give you very much testing solution. My advice is to buy an extra one up front when you purchase this unit.
