I have been emailing back and forth with Hanna over the last few days. After explaining my procedure and clarifying phosphorus vs phosphate a few times, the folks at Hanna confirmed that my math was correct. The only thing they could think of was some potential interference from copper, iron, silica, silicates, etc. These are generally not present in high enough quantities in reef aquaria to meet the interference levels that Hanna quoted, so I don't think this is likely.
I haven't decided if I want to order their calibration standard. I think I'm going to put this in a box on the shelf and forget about it for now. Maybe after a few weeks or months pass I'll be willing to waste some more time and money seeing if this thing actually works or not.
