Alkalinity Colorimeter HI755 Hanna Checker HC - Marine Water

SKU: 206201


  • Great little device! By Jonathan on 11/19/2014

    Moved my reef to our new house, and everything was great for about a month. Then my SPS started taking hits left and right. My old ALK test was not giving me results I liked (likely due to the age of the tests). Once I got this I quickly found that my Alkalinity was far too low.

    This tester potentially saved the rest of my tank. It works great and is almost too easy to use.
  • Will fight you for this tester! By Ryan on 11/7/2014

    By far the easiest way to check Alk.
  • Works like a champ By Ray on 10/27/2014

    Fast and easy. Spot on match with titration test but a whole lot quicker and easier. I will be adding more Hanna checkers to my collection.
  • Good meter By RSeahorse on 10/24/2014

    I like this meter, it's easy to use and seems to be accurate.
  • Easy to use and fast results! By Brandon on 9/15/2014

    I absolutely recommend this product. The instructions are very helpful but after the first couple of times of testing you won't need to use them. It gives you your readings in ppm (parts per million) but includes the conversion ratio on the instructions which converts to a very precise measurement of dkH.
  • Consistent & easy to use By Dylan on 7/31/2014

    Testing your alkalinity has never been easier. You can get an accurate reading in less than a minute. This product also gives you a consistent reading, just make sure your reagent has not expired.
  • Ease of use By David on 7/30/2014

    the ease of use is what I like the most about this... well that and its accuracy. recommend it to those like to know exactly what is going on in their reef.
  • Just what the doctor ordered By Johno27 on 6/16/2014

    I have been looking for a quick and accurate way to test alk and this is just what I wanted. No more color changing or counting drops!

  • Easy to use By Charles on 4/26/2014

    I have been using the Hanna checker for 3 months now. I don't think I could ever go back to any other type of test kits. I love the repeat illite of the test results.
