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.

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

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 7/20/2013

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.
