  • The best…..when it works By Mcmullen on 4/8/2016

    So this is easily the best Alk checker when Hannah has their reagent working properly. Sometime in Novemeber 2015 (maybe sooner) they changed packaging so that when the liquid reagent encounters the bottle lid, it somehow deactivates the reagent. This was addressed, and supposedly fixed! Well, guess what? Still same problem!! I finally ordered a "Salifert" kit and my Alk level tested higher than the max level…..the max is 15.8! I kept dosing Alk based on my Hannah reading low levels. For those of you that do not know, anything higher than 12 is high for Alk, and my tank runs about 9. This is a sps killer. I do believe Hannah will fix the problem but how can you trust the product. I'll constantly be double checking!! I cannot recommend at this time!!!
  • Excellent and easy to read. By DAVID on 4/3/2016

    I find this one easier than API or Red Sea to read. I just made a ALK Table with the reading and dkh. So all I have to do is look at my chart.
  • SUPER EASY TO USE! By TWang on 3/1/2016

    This is very easy to use and is accurate. Kind of pricey but well worth it.
  • great product By Jason on 1/25/2016

    Super easy and always accurate.
  • No more guessing color. By Reefdoc on 1/16/2016

    Works great! Takes the guess work out of alkalinity testing. This is my first hanna checker and now I'm going to be replacing my other testing slowly with Hanna checkers.
  • Easy and Precise By John on 1/16/2016

    I had been using the Red Sea Foundations test kit, which I think are one of the better test kits, but this Hanna Checker is fantastic. It is very easy and I love the precise reading. I also bought the Calcium checker.
  • Easy to use just follow instructions By Jeff on 1/13/2016

    I am trying to be a much better aquarium keeper starting this year 2016. Had my water tested and both alkalinity and PH were low. using a Reef Buffer 8.3 to raise the PH and Alkalinity and this meter help to know parameters so that you don't shock the fish as your trying. Much better then counting drops like the other testers.
  • Great product and easy to use By jsbull on 1/2/2016

    You put tank water in the vial and push the button. Then add 1ml of regent, invert the vial a couple of times and push the button again. Can't be easier and it does give more exact results than the API style test kits.
  • Great By Eric on 12/27/2015

    Its fairly quick and very accurate. Only downside is having to clean the glass bottles after using. But it makes up for it.
  • Perfect! By ducannn on 12/21/2015

    Accurate, easy to use, affordable. What more can I say.
