So in this same vein, can someone talk me through the benefit of using a saltwater analogue for reference solution (just iodized salt) vs using a fresh aquarium salt mix that is then spiked?
I don't know the answer about the reagent grade and morton's....Reagent grade is 99.99% sodium chloride so I feel confident it is low in contamination....I don't know about the analysis of Morton'swhat level nitrates have you seen in the past?
Is there an appreciable difference between reagent and Morton's?

I have not done any work with the Salfert kit...but it is interesting the level of color this kit produces...might be worth a look to see if could potentially offer a wider range of testing and possible give more accurate readings in the low range.
Great to hear...Thanks for the feedback!Man, i just picked up the red sea no3/no2 and ran some standard tests on it. They were all within 0.5 ppm. I'm very impressed with the results of this method! I dosed my display and my frag with kno3, tested before and after. It a) supported my tank water volumes and b) gave me accurate results. I'm very pleased!
