  • a must for a reefer By machote on 3/27/2015

    one of the items you need the most if you plan on reefing you cant just try to have corals with out alk test, and this is the best one for it speed and easy use
  • Nice for the color blind!!! By Mikey Reefs It on 3/25/2015

    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

    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.
  • Great! By Patrick of Bay Area Coral on 3/16/2015

    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.
  • Very Easy to use By Dave on 2/23/2015

    Took me about 5 minutes to read the instructions and perform my first test. Very easy to use.
  • 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.
  • Works Great No More Guessing By Ceasar on 2/4/2015

    Easy to follow directions, not very tedious, and most important of all accurate.
