I got my ICP test results and had a couple of questions. First, it looks like my salinity looks low, but my tests show it at 1.026. I use a Milwaukee meter (35 ppt) and just double chec,ked with a refractometer (1.026, and verified with BRS calibration fluid that it's exactly on target). So do I trust this test, or my calibrated equipment? Looks like I can bring up my trace elements a little too - I had been dosing Red Sea trace (ABCD) but have held off for a couple of weeks until I got this test back. The calcium was spot on with my test and while I didn't test the mag, it's in line with what my tank typically runs. For phosphorous, my test came in at .074 ppm and the ICP says 0 ppm, so I'm guessing that may be within the margin of error?
Bottom line, I'm not sure what, if anything to do here (other than to dose trace). I don't want to raise salinity when my testing disagrees with the ICP results.
