There are no known detrimental effects on plants at extreme levels(NH4
is quite another matter), fish and the most sensitive will be Amano
shrimps etc.
I used these shrimp in a toxicity study, I found no adversed effects
at 160ppm(the limit of the test method, it was likely higher). No fish
or plant impacts where noted. I used KNO3 to dose, as did Paul.
I slipped a decimal once and dosed at 200 ppm of know instead of 20.
I let it go for 3 weeks to see what would happen. The tips of a couple
of crypts curled a little bit but the 16 ammano shrimp were unaffected.
