  • Finally no color chart!! By Travis on 9/22/2014

    It is easy to use and the instructions run you clearly through the steps. Love having an actually number instead of color charts, no guess work. Thank to the other reviews I did order extra regents. Thank you to the other reviews and to BRS for putting review sections on all of their products.
  • A good test kit! By Brandon on 9/15/2014

    I love the digital output on this test kit. My only concern the possibility of human error that can throw off results. I say this because the reagent comes as a powder form and it comes in its own little packets. I don't really like the packets because it is impossible to get all of the reagent from the packet into the test vial unless you open it up and scrape it with a blade. I would have rather seen a container with a measuring spoon like the on in Red Sea's Calcium test kit. Other then that I do really like this test kit and I would recommend it.
  • No more guess work.. I think By jmar on 8/27/2014

    Accurate measurements, and includes a storage container for everything along with a laminated instruction card. It is a chore to get all the powder into the vial for the test. Work fast, or do some prep work beforehand. Several times I thought I got all the powder only to find that there was still a bit more in the packet. Take your time, get all the powder into the vial first and then calibrate. It includes 6 reagents so add those to the cart as well.
  • Great little device By Devin on 8/21/2014

    Product works great with fast results!! one thing i would say is get more reagent when you order the checker!! Also for best results clean the glass well, and swirl to avoid bubbles!!! Great product!!!! Accurate!!
  • I love this thing By JR on 8/20/2014

    if you have hair algae, you have phosphates....period. No matter what i used I kept saying to myself "my kits show no phosphates. I had to give in and get this Hanna Checker and it was the best move ever. Combined with my GFO reactor and I had a happy tank in no time. I wish the kit had more reagents, but if i had a controlled tank I wouldn't have had to check so many times :). Great product but be very careful with the vials to ensure they are CLEAN and scratch free prior to running your tests. It could skew the results.
  • Needs more reagent packets By David on 7/30/2014

    I have no issue with the checker or its accuracy (it works great) the only issue I had was that it only came with 6 reagents. for those that like to test on a regular basis I suggest you buy some with the initial order. besides that its awesome.
  • a product that gets you a phosphate reading you can trust By Ricky on 7/16/2014

    I like a lot of people have a hard time telling with certainty what the phosphate reading is with the liquid or even titration tests. No more guessing with this tester.
  • great but a little tricky By Jonathan on 7/16/2014

    It took me a few times to learn. I use both test tubes, makes the testing easier. Make sure to wipe off glass test tube even small print can mess up the test. Apart from that great.
  • very accurate By swseipel on 7/6/2014

    This meter is awesome. ..very accurate. Easy to use
  • Work great By Christopher Kirkland on 6/25/2014

    Very accurate, does take some practice to get use to using it correctly. There are several youtube videos that help along with that. Love the tester.
