Hello. I am building an aquaponics system, and I would like to try out peeponics first to start the nitrogen cycle without fish for now. I have read a few websites such as: https://sites.google.com/site/aquapanaponics/4-project-updates/pee-ponicsphplanting http://community.theaquaponicsource.com/profiles/blogs/how-to-build-a-4-x4-ebb-flow-bioponics-peeponics-system?id=4778851%3ABlogPost%3A417362&page=1#comments http://www.aquaponiclynx.com/pee-ponics Specially from the latter, I understand that its a matter of storing my urine for a month and then the ammonia-ammonium readings should start peaking. I'm using an API Test Kit to detect pH and ammonia levels: http://www.apifishcare.com/product.php?id=580#.VZyiXrzarbM The problem is, after 7 weeks, I cannot get the ammonia-ammonium test kit to detect the slightest ammount of it! It's always been 0! pH did raise after I left one of the bottles without its cap and measured a wekk later, around 8.8, but thats it. Without being able to read ammonia, I would not know how much urine I have to dissolve in my 200L aquaponic system. I have been inyecting urine directly from the bottles I stored them in, and into the testing tubes (5ml). Any help will be welcome.
