  • EASY TO USE By KONQUEST on 1/18/2015

    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
  • Awesome By Marine1 on 1/17/2015

    Best alkalinity tester on the market!
  • 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

    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)
  • nice piece of equipment By Daniel on 12/28/2014

    Makes checking alk as easy as possible. Very accurate.
  • Forget the dropper kits By David on 12/22/2014

    This is way easier than test tubes and counting drops. And gives an accurate readout on a digital display
  • Simple, easy, accurate. By DivingTheWorld on 12/19/2014

    Simple to use and accurate readings.
  • Works Like a Charm By ncoble4 on 12/15/2014

    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.
  • Easy Alkalinity - works great By Jon S on 12/15/2014

    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.
  • Makes reefing life simpler!!! By Darren on 12/15/2014

    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.
  • hanna checker hi755 By chuck on 12/14/2014
