I have the or nitrate checker, and several tests I’ve had this issue. I will run a test, and get the blinking 5.00. So I run another test with dilution, and like today I get a reading thats say 4.4 (.44 prior to the x10). I’m using seachem seawater calibration solution to dilute because I’m not sure what else would have a nitrate of zero. I think 3 times now I‘ve gotten the blinking 5 but then get a diluted result below 5.00.
help? Thoughts?
