Hanna ULR HI736 Help

Stingray122 · Apr 13, 2019

Hey guys, picked up a Hanna checker because I wanted a reliable way to measure phosphate (or phosphorous in this case) because I believe my nutrients are a limiting factor in my reef. I ran a test yesterday, and got a reading of 0.02 on the display, and today a reading of 0.07. I did the conversion to get this to ppm from ppb and got 0.0002. Is this correct? Or is the device I have converting it to ppm for me? If I am correct in my math, that is crazy crazy low, or am I crazy? Thanks for the help!

Nevermind I am an idiot, and not crazy. I have the HI774 that measures in ppm. Oops!

Hanna confused us all by releasing the HI774 sometime late last year. Just make sure to get the correct reagent!

If only they had one for nitrate as well. Maybe someday!

Edit: They do, surprised I have never seen this before. DELETE THIS THREAD I AM EMBARRASSING MYSELF

Really? I only see Nitrite checker. What is the number of the nitrATE checker that you found?

Please don’t say it was one of the BRS 1-Apr special offers like the sand roomba, or never ending, nonexhaustible GFO.
