Awesome, Easy and Accurate...Consistent By JPB on 2/13/2014

Easy to use and very consistent results. For the first few months I double checked occasionally with a Salifert titration test...results very similar. Titration can be challenging to determine exact endpoint, especially if you rush it...not at issue with this test. :)

I am new to the hobby and found this checker very easy to use. None of my criticisms of the phosphate checker apply here - no problems with timeouts or reagent packets. The results are easy to read.

This is a very easy test kit, and will never use anything else.

I like the digital read out but still quite a few steps involved, wish it was a bit easier.
Fantastic! Never going back By David on 1/14/2014

Pros: Results are fast and easy with less mess than other tests. Only having to add reagent once to get a result is nice. Seems to be accurate as far as I can tell.
Cons: Printed instructions are difficult to read - need to be printed more legibly. (Test process is very simple though.) Display is hard to read in low light. Size and shape of the device could be better for easier handling. Would get 5 stars with those simple improvements.
Accurate But Expensive By Scott on 1/9/2014

I really like my Hanna checker and found it to be very accurate when compared to Red Sea and Salifert. My only gripe is that the reagent is expensive.

Stop the guessing By Kristopher on 11/25/2013

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 11/9/2013
Kenneth would recommend this product to a friend
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.

I love the ease of this tester ! It should all be this easy ! My wife loves it also, no more color charts ! I will in time only have these testers!

Better than tritation test, only test kit I will use to check my Alkalinity

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 7/20/2013

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 7/15/2013
Kash would recommend this product to a friend
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.
Accurate, easy to use By Brandon on 6/1/2013

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.
