  • Controlling Phosphate

Phosphate Low Range Colorimeter HI713 Hanna Checker HC - Fresh & Marine Water

SKU: 206200


  • 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.
  • Works like a charm - once you understand it By Paul on 12/8/2014

    Received it, and with it being the first time I've used this type of product, the instructions weren't overly clear, so I used 2 packets of powder to test...both tests came up at 0.00. Odd since it's pukani rock. Played another time, and got my reading that was right.

    Product works great now. Wish they gave you more than 6 packets of powder though.
  • Great tester By Andre on 12/6/2014

    Its a great tester very easy instructions better than comparing colors.
  • Actually use the tester! By Bridget on 11/10/2014

    I have purchased a few different test kits and don't use because it was hard and what color actually was the reading??? This is great with a display. The only thing I don't like is the packets of powder. Wish they did a little jar of powder instead with a scoop, like Red Sea does.
  • digital is AWESOME!! By Mike on 10/30/2014

    Very accurate and you can not bet digital!!
