A few quick observations.
1. I wounder why you have an ammonia reading. The bacteria which cause a bacterial bloom are not the same ones which handle nitrification (converting ammonia to nitrate). The bloom type bacteria can double fast, the nitrifiers take 8 -12 hours in optimal conditions and longer if conditions are not optimal. The bloom bacteria can use ammonia etc.
2. Some bacterial additives which are not the ones I would recommend often contain bacteria which will cause a bloom and/orthe nutrients in the bottle which can. I suggest using Dr. Tim's One and Only or Tetra's Safe Start (they are basically the same).
3. I know this will ruffle some feathers on the site, but I do not endorse the directions here for doing a fishless cycle. It suggests using too much ammonia and dosing it too often, imo. I have a cycling article on another site but I will not link to it as that is not right. What I can tell you is it is a variation on that suggested by Dr. Timothy Hovanec who with other researchers identified the specific strains of nitrifying bacteria in fw tanks. The problem with Dr. Tim's directions is they use the more scientific nitrogen scale to measure ammonia and nitrite and most hobby test kits use the total ion scale. My cycling article is written for use with this type of kit. (there is a formula for converting between the two scales.) Here is the link to Dr. Tim's cycling info http://www.drtimsaquatics.com/resources/fishless-cycling
After reading it at the bottom you will see two links. Please click this one DrTim’s Guide to Fishless Cycling
and read it as well http://www.drtimsaquatics.com/resources/how-to-start
If you would like a copy of my article, you can shoot me a site PM with your email addy and I will send you a copy.
As an FYI, the very first fishless article I have located was: Originally published as: Koga, James S. Use Household Ammonia to Humanely Cycle a Tank.
Freshwater and Marine Aquarium, 19, no. 4 (December 1996): 213-214. He revised it over time and lowered the ammonia amount. You can read it all here http://www.cpp.edu/~jskoga/Aquariums/Ammonia.html
