I started measuring PO 4 in my tank about 2 weeks ago. I am using the BRS Dual reactor for phosphate and carbon. My phosphate measurements have been pretty erratic from 0 to .02 and then to 0 followed by .04, .02 and 0 again. I just wondering what everyone else's experience is . I'm using a Hanna checker so I think it's pretty accurate and I do the test the same way every time....any thoughts?
