I actually found this web site and posted on a forum concerning ammonia.
Let me think ,, oh yes. Pee in your tank.
Seriously, if you don't have/can't get uncontaminated ammonia freely where you are or something. take a cup and pee a little bit in it and add it to your tank.
I've just started my own tank 3 days ago and have done the same thing.
not with fish in there, and I'm not going to put fish in until there is a healthy nitrogen cycle going on and the ph and everything is stable.
I'm not in any rush.
I actually only posted on the site because the comment I spotted said fish urine and human urine need a different bacteria to break down.
This is true initially, as Human urine contains urea, which is then broken down into ammonia by a bacteria that will not hang around once the urea is no longer present and will be replaced by the guys you want that degrade ammonia.
(side note)Urea is what your liver turns ammonia into inside your body as ammonia is toxic to humans. so people with bad livers, kinda suffer ammonia poisoning and that's why they need to go on blood dialysis.
also when we are dehydrated our ammonia levels in our blood increase.
Now the reason i posted was the comment I replied to stated fish have copper based blood and humans have iron based blood so the bacteria will be different. This is false, fish bleed red, red blood cells are found in iron based blood. copper based blood is blue/bluish green and it's what you will find in squid,octopus etc.
Fish blood cells are different to Human blood cells in that they have a black dot on them but they are both iron based.
