I ordered new reagents for my phosphorus ultra low tester. Tested and I got 200ppb. the water turned blue before I started shaking for the 2 minutes. I had one package for the original 6. I tested and it showed zero. What the heck. total rip off.

Look up a couple post. I took picture of the box and the new reagent. also there is a picture of the old reagent.Do you have the phosphate ultra low or the phosphorus ultra low. All three different Hanni phosphate checkers look alike but all take different reagent. I would try running test again. If it is still not the results you expect post a pic of your tester and the reagent pack.
I am a slow typer. It wasn't there before I posted. Then after I posted and the page refreshed it was. I edited the post when I seen it then it refresh when I posted the edit. Sorry. Just trying to help.Look up a couple post. I took picture of the box and the new reagent. also there is a picture of the old reagent.
I retested with the last reagent from the original 6. I will retest tomorrow with the new one. I will not make changes till I know what is right.I have been using that same tester over a year. I test almost daily so I go through almost a box a month.
Have you had a second test from the box give a similar reading. If I ever get a reading I think is not right I always retest. As a rule I will never make a change to my tank based on one test. I treat all and phosphate daily and o ly make changes when I see a trend over a couple of days.
