Whoa, opened a new box of HI736 Hanna ULR reagents and this is what my sample mixed up to, lol. Either my phosphates just went through the roof (too high to get a reading...kept flashing 200) or a bad reagent pack... turned out to be the latter, retest was more in line at my expected 0.07ppm PO4! Hopefully this was only one bad packet!!
HI736 lot # H082 (exp 10/2021)
For reference, the sample vial for my tank is almost clear to a barely noticable tinge of blue, lol
