Hi, I was reading the page: www.aquarium-pond-answers.com/2007/02/aquarium-test-kits.html and came across an image for, "different "Total Ammonia" levels versus Toxic NH3 Ammonia." I am currently doing a school project on Aquaponics and I was going to source this image as a measure for lethal values of ammonia levels for the fish in my system (common goldfish for now). I can see the different colours to suggest the danger those levels pose to the fish but I was wondering how you got those values? Did you do your own testing to find the values in the amber and red zones or did you use another source to find them? If so, please could you link the source?

If I understand your questions, these lethal values published on these test kits are simply generalizations.
There are many variables, including how much NH3 versus NH4, pH (which affects NH4/NH3), time of exposure, aeration (dissolved O2), nitrites, and the fish involved (I've not done specific tests as to whether Goldfish are more or less susceptible to ammonia poisoning, but anecdotal experience is they are right in the middle)

I believe the graph is a generic graph known in the science community. It's not something made by the author, just used to make a point.
