    Have used for many years.
  • Dissolved Better By Dave G on 12/16/2016

    The last couple of refills seems to require less shaking to get it to dissolve. I don't know if they changed something but dissolved better now. The was always my biggest complaint was how vigourous you had to shake it and sometimes the checker would shutdown before you ever finished getting it to dissolve.

    I have always had good luck with this product
  • Just Fine By Brett on 3/28/2016

    These packets are just fine. The manufacturer obviously used this packaging assuming that most people had common sense enough to be able to use it. All you have to do is cut along the line, fold into a funnel and pour it in. I actually have my 5 year old doing this for me on a regular basis. Hasn't lost a test packet yet.
  • Good readings but tricky reagent By sjohnson2152 on 2/24/2016

    Best way I've ever tested phosphates and gives accurate low readings you cant get with other test kits.

    My only complaint with running the test is these little packets of reagent. They are not the easiest thing in the world to work with, although I am getting better with practice. The powder inside each of these reagent packets is very fine and difficult to get out of packet and into the tiny top of the test vial quickly without spilling a bunch of it. I tried a tiny plastic funnel once but the powder is so fine a lot of it stuck to the funnel so I was worried this may skew the results of the test. I think I would much prefer to have the powder in a little jar with scoop and then would probably be able to say 5 stars.
  • Best way of calculating total phosphate in tank By Dave on 2/21/2016

    The Hanna Phosphorous Checker lets you know how much total phosphate and potential phosphate is in your tank by measuring total phosphorous. A simple equation gives you the best overall view of phosphate in tank. I will continually use this system until a better Hobbyist level test is created.
  • Easy to use, worth the price! By Jwill275 on 1/31/2016

    so far so good! Getting better at using the equipment, preparation the key.
  • excellent product By acalderon on 1/14/2015

    excellent product for very precise measurement of phosphate
