Most water reports here state nitrates as in the form NO3-N but test kits read NO3. The conversion rate is 1 NO3-n is 4 no3I want to say I did but I want to make sure and get back to this in another week. Initial results are undetectable by API test kit in all three categories.
According to https://www.ewg.org, my city has a reported average rate of 3.39 ppm Nitrates from 2010-2015. Health guidelines are 5 ppm and under. Legal limit is 10 ppm.
Anyways... Need some chemistry here... Brainstorming how perfectly clean water becomes fertilizer in a week...
Chlorine in water... we have hypochlorous acid (HOCl), and hydrochloric acid (HCl)
Weco Dechlor (sodium thiosulfate ).... Na2S2O3
Nitrates.... NO3-
Which would kind of explain what your seeing
