Does anyone have a Hanna PO4 (ULR checker HI774) and the Salifert PO4 reagents?
I just tested mine using the Salifert reagents and the test came back the same ballpark as the Hanna reagents for my acropora tank (0.16)
I did not wait the 3 minutes and perhaps I should have as the test on the larger tank came out higher but I think there were still some bubbles from the vigorous shaking.
Does anyone else have these on hand and would be willing to do a comparison? would be interesting to know because I have no use for my PO4 salifert reagents otherwise.
