  • will order again By mike on 10/24/2014

    Really nice product just takes time to pour the reagent but it's worth not trying to match colors
  • Good product by a great company By Christopher Kirkland on 6/25/2014

    Works very well. Had one bad reagent (empty pouch) come in. Called hanna and they replaced the whole box. Very accurate and super easy to use.
  • Work as promised By Chicago on 3/25/2014

    I have used these for years with great success. Good company. Any issues just contact Hanna. I called once to question the reagents. They sent out a new batch no questions asked. A complete box. They also asked what batch number I was using. Seems they track to see if any ate bad or having issues.
  • Great product By Ourisland42 on 2/20/2014

    No more color wheel!

    Buy in larger quantities to lower your overall cost. I just cut off one corner that is about the opening of the container and tap the powder in. Excellent product, will reorder......... BRS is great!!!!
  • Worth it, for accurate results. By Felixpaws on 12/20/2013

    If you can get these with points, on sale or both, I'd recommend getting these. The Hanna checkers aren't more convenient, but more accurate than regular tests. For the price, you could get a Red Sea or other name brand reliable test kit, and compare results. Taking the middle ground on the numbers would be safer than just trusting one kit over another. Test with three good test kits, compare results, choose the median, and go from there. Easy peezey.
  • Worth the effort By bdmyers on 12/17/2013

    Takes a little extra time, but knowing you are getting an accurate reading and not a false sense of security makes it worth it.
  • I finally know what my phosphates really are. By bdmyers on 12/17/2013

    Yes, it is a bit of a pain to use, but knowing I'm getting an accurate measure makes it OK. I'd rather make the extra effort and get a real reading than do it the easy way and get a false sense of security.
  • as test kits go By mark m. on 12/7/2013

    Test kits are a personnel choice. The product speaks for itself. bulkreef supply shipped when they said and every order arrives as described and in good condition.
  • Best Product for testing Phosphates By Kenneth on 11/9/2013

    This is the best product for testing Phosphates. I have taken all the guess work out of doing your phosphates test. No quest on how much chemicals to put, no guess on what color does the solution match. It is fool prof.
  • a pleasure By dru234 on 8/29/2013

    It's always a pleasure to use the Hanna phosphate checker and reagents.It's quick, efficient, easy ,inexpensive and accurate.. The guesswork and difficult color matching are taken out of the equation.
