  • Confused for why it is continuing reading 0.0 ppm By on 4/5/2017

    I have had this product for about a month or 2 now and it keeps on reading 0.0, Not sure if i have a one that is broken. I will give a future review.
  • Excellent - reliable and accurate By on 3/6/2017

    I really think this is the best test kit you can buy for Phosphates. It gives you a very accurate reading and it gets the job done in about 5 minutes. Simple to use. I would though prefer the regent to be liquid than powder but other than that small detail this is a great item and I would recommend it to any hobbyist who wants an accurate reading.

    This was my first HANNA checker purchase. Ive been hearing all the rage about these for a while so i finally tried. Very east and simple to use. Less then 5 minutes to test and get results. Definitely will be trying a few other HANNA checkers now.
  • **Be Aware** Not Suitable For Reef Aquarium Testing! By on 10/16/2016

    Not sure why Hanna doesn't just Discontinue this product even though they know it's more suited for "Fresh" water than marine usage. I've owned this for 6 months and never had the digits read above 0.00 ppm! Had the signs apparently of having phosphates with algae growing constantly on my glass! Went and purchased RedSea's Phosphate test kit and Salifert's test kit just to make sure and too my surprise not only I had phosphates present in my reef tank but that the results showed RedSea 0.8 ppm Salifert 0.07 but yet my Hanba HI-713 can not detect these units! I emediatly called Hanna Headquarters in Smithfield Rhode Island and to my surprise, they told me that the HI-736 ULR which is the "Ultra Low Reading" test kit would be more suitable for me, which really indicates that thier aware of this problem! IMO, maybe they just never made an attempt to recall this model of kit in in order to save tons of money they just went ahead and slapped on the "Fresh & Marine " label and kept it as is but clearly if you don't see a "Fish" label in front of your handheld with the "Marine" label as well than it's not suitable for Marine! Unfortunately this problem is not going away! Reefers Be Advised, purchase the ULR instead!
  • The product it's really easy to use By on 10/2/2016

    Hanna Phosphate Low Range Colorimeter works well . Fast and accurate
  • Great.. packaging needs improvement. By on 9/26/2016

    The product it's great and easy to use. Take away from having to match colors. However, the packages the reagent comes in need to be replaced with a scoop method because it's hard to get all the power out of the packages.
  • Unsure of accuracy By on 9/3/2016

    Iva had this a couple weeks now and have yet to get a reading above 0.00 after 4 tests. I run hc gfo but should still have some phosphates right?
  • Really only 6 tests By on 7/15/2016

    I am disappointed with the fact that it only comes with enough regent for 6 tests. Sure the digital read out is awesome and very helpful, but I really feel that for the price I should be able to test more than 6 times before having to give them more of my money
  • Easy to use By on 4/6/2016

    I hate trying to match colors on tests (ok, I'm also slightly red-green colorblind so that doesn't help!) and this makes it so much easier. Doesn't come with very many test packets so if you'll be doing a lot of testing you'll want refills but they're pretty inexpensive.
  • Dies right after warranty By on 4/6/2016

    Problems with the light sensor the minute the 6 month warranty was up. Randomly worked and then completely dead. Tech support offered up $95/hour service or they said I'm welcome to order a another from them. Don't think so. The results I was able to get when it worked were extremely varied and I couldn't stand trying to get all the powder out of those tiny packets. Need to rethink design on those. Not pleased unfortunately.
