Welcome to TFP!
The experiment was already done and the myth busted. We were talking about small quantities of chlorine and ammonia
in a larger volume of water, not concentrated solutions.
I agree you do not want to mix those concentrated chemicals together, but that wasn't the experiment. The original quantities of 1-4 gallons of ammonia and then shocking with chlorine are very dilute in a pool with many thousands of gallons of water. The bucket experiment would use similar scaling of dilution or perhaps somewhat more concentrated, but certainly not only ammonia and chlorine themselves. 20 ml of ammonia (household ammonia is usually 5%-10%) was put in 10 liters (10,000 ml) of water and 20 ml of 4% bleach was also used. The amount of FC added was around 80 ppm and if that produced monochloramine that is not enough to produce noxious monochloramine vapors though the smell could be noticeable. It would be VERY irritating to the eyes underwater so is not something to swim in, but that wasn't the experiment.
Note that the
Coral Seas® Green to Clean® product has
this MSDS showing it is essentially EDTA with ammonium sulfate. When added to a pool with chlorine, it will produce monochloramine which kills green algae even in pools with high CYA that would prevent chlorine from doing so. As shown in
their instructions, one should never pre-mix their concentrated chemical with chlorine. Their instructions raise the FC level to 10 ppm and since 28/(292-2+46+36+132) = 5.5% of the weight of their product is ppm N from ammonia that would be 0.9 ppm N (from 16 mg/L of added product). This would initially and quickly form around 4.5 ppm CC as monochloramine though over hours would get partially oxidized by excess chlorine. They then later superchlorinate to further oxidize the monochloramine to get rid of it.
Anyway, there's no reason for anyone to now do the experiment since it was already done and demonstrated that the CYA was not reduced by this method. It didn't make much sense that it would, but it was worth a test.
