I have a doctor friend that is able to determine the Ammonia levels of various aquariums just by looking at them. Apparently he is able to detect the minor changes in color due to Ammonia levels. Does anyone else have this ability? Does anyone know how to teach this process so we can save money on test kits?
He is also able to do it to some degree with pH levels, although he is not 100% accurate like he is with the Ammonia.
