  • Just short of great By ONAP on 1/19/2015

    I really love the idea of this test meter, but the execution needs a little help. For the most part, it's great. Love the design. Easy to use. No guessing at colors, unlike other test kits. The only real issues that I have with this tester are the limited number of reagent packets provided with a new test kit, and the reagent mixing time. The instructions tell you to shake the vial for 2 minutes after adding the reagent. The problem is that the meter shuts off after two minutes. Another sixty seconds and a few more reagent packets, and this would be a five star product.

  • Accurate and Easy to use By Dieter on 1/11/2015

    I like this test kit. For less than $50, I find it to be a bargain. Its easy to use and doesn't take long (about 5 minutes total). It's an important tester to have if you have a reef tank.
  • great product By Daniel on 12/28/2014

    Very easy to use. Very accurate.
  • Simple and accurate. By DivingTheWorld on 12/19/2014

    This is a very simple and accurate test for phosphate.

    The one thing I will say though is that you need to use both test vials at the same time. The instructions talk about going through the test , then adding the powder, then shaking it up, then putting the vial back in. The shaking/mixing takes 2 minutes and the checker turns itself off during that time... So I fill both at the same time, add the powder to one, shake it up, then run through the test.

    Works perfectly this way with very accurate results.
  • A "need to have" item. By Darren on 12/15/2014

    It's extremely hard to gauge phosphates with other tests because you're trying to pinpoint color differences with the naked eye. This gadget does all the hard work for you in minutes!!! Amen
  • Way better than matching colors! By Josh on 12/12/2014

    This meter is great. It takes a bit of practice to get all of the reagent into the sample but it's much better than training to match to colors by eye.
  • Makes testing easy By Justin on 12/10/2014

    I bought this cause I used other test in the past and can't get a good reading. 0.0 - .25 how can u tell exactly what your levels are at. I'll tell u Hanna checkers. Gives u a digital readout I love that. I have the phosphate and alkalinity tester. Works great. The only down fall is buying the test solution. It's a pain to have to order it and for 10$ for 25 kits it's not the cheapest test kit. But I wouldn't use a different test again.
  • It's OK By Bill on 12/9/2014

    Bought this tester to help dial in biopellet reactor. The test results seem accurate. But with multiple test obviously required to know what's going on with the biopellets the few test packets included didn't last long at all.getting the powder out of the packet and into the test vile seems challenging. Would have preferred a bottle of powder and small scoop like every other quality test kit has.
  • Great piece of equipment By Dave on 12/8/2014

    I so glad I have an easy way to test for phosphate. I hated having to run from room to room trying to find the right light to analyze results and even then not knowing if I was interpreting the result correctly. I don't have the problems others have mentioned with adding the reagent, you just need a steady hand. I will order all the others in time.
