  • Controlling Phosphate

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

SKU: 206200


  • 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!!
  • Who Doesn't Love Digital? By ReefAddict on 10/28/2014

    Not the cheapest, but the most accurate and easier to read. Easiest test of any of the phosphate tests I have ever used. In the end, it was worth the extra money.
  • great product By mike on 10/24/2014

    This checker is very easy to use and very accurate. The only downside it pouring the reagent into the vial. Just need to be careful.
  • 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.
