How long does it take for nitrites to show up in a fishless cycle?

I am currently on my 8th day of fishless cycling. 8 days ago I added 5mL of ACE 10% ammonia solution to my 29 gallon aquarium. I've read on multiple fish sites that niTRITES should have already been registering on the test kit by now (API master) but so far I have no niTRATES. I've been a little worried since the first day I've started the fishless cycle with too much ammonia, I did a 25% PWC yesterday and the ammonia to me at least still looks to be the same level as before. It's really hard for me to tell which green it's on with this API kit. Anybody that's done fishless cycling, how long has it taken before you've seen any niTRITES? Should I drain all the water and start over? Any suggestions on what I should do? Or do I just have to wait it out another week...
