I believe someone of the forum wrote an article about how human urine doesn't contain ammonia and therefore is no good peeing in your tank to cycle it.
there is no ammonia in urine. simple as that really. urine does contain urea, as already stated, which is alot less toxic than ammonia.
unless bacteria is contained in urine, such as bladder infections or after its been left on a wall or in a bus shelter , the urea can then be broken down and ammonia is a product of this... hence the stale smell
Regardless of what urine contains, I still think it is morally wrong, Next they will be putting puppies and kittens in baskets for people to have a wizz on.
