  • 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.
  • easy By tim on 12/20/2015

    very easy to use
  • Much easier than I expected By Olliesshop on 12/19/2015

    I'm very pleased for how easy and quick it is compared to the titration method I have been using. I also like that it won't turn off for 10 minutes vs. 3 minutes for the phosphate Hanna Checker.
  • Best Alk Tester By Matt on 12/19/2015

    I get identical results to the Red Sea Pro Alk test but Hanna is much easier to use.
