yep...i am the guy that used human urine to cycle a tank.it worked perfectly..i did it awhile ago just as an experiment.at the same time i also did the ammonia cycling too.it also worked.nothing new about ammonia cycling;been around for many many decades.
i don't tell folks to do what i do;because i never do anything by the books.my tanks are overstocked and overfed.i never cycle.i may tear down 4-8 tanks at a time.i will pull the fish;drain the tank and scrub it out.then refill it add dechlorinating agent and put the fish back in.
fish exporters,importers,wholesalers and retailers do not do fishless cycling.breeders do not do fishless cycling.fishless cycling is left for hobbyists to do.for anyone in a more commercial area it is just not economically feasable.
hmmm..i guess you could say that urine is gross and it smells bad..but does anyone really think that ammonia smells any nicer...lol....and it is possible in an emergency situation for one to drink their urine..but certainly not ammonia.
