OK here are 4 measurements off the same water sample from a freshwater planted tank:
Sample 1: 1.34 ppm Sample 2: 1.06 ppm Sample 3: 1.35 ppm Sample 4: 1.35 ppm After running sample 2 I realized I had not got all the reagent powder into the reaction vial as some of it spilled. So far it seems that the readings are fairly consistent from one measurement to the next if I through out the one bad measurement. This says nothing about whether the measurements are accurate or not. Next: to repeat the measurements with a saltwater sample.
