I've been fishless cycling my 29 gallon freshwater tank. I've added ammonia and bacteria (a few times) but I'm seeing no results. Ammonia is 2.0, nitrites and nitrates are both 0. It's planted, I've got plenty of oxygen circulation, everything is functioning properly.
Any ideas for speeding up the process, or as to why the bacteria are not colonizing?

If your water is very soft, you might want to add some carbonate buffering.
7 carbonate molecules are used for each ammonia molecule processed by your filter.

Your plants may be absorbing all of the ammonia.
Did you fill the tank with water from your tap? If so, I really doubt you're low on carbonates, unless you have very soft/acidic tap water (it's generally kind of rare in the US).
My tap measures kh 1-2. Common in this area. If I don't add buffer tanks crash hard.

I concur with Entomancer that the plants are taking up most of the ammonia. This is their preferred source of nitrogen, and they can take up quite a lot of it. Some will still get left for the nitrifying bacteria, but it will be less obvious.
I never "cycle" tanks as I always have plants, especially floating which are fast growing and thus use even more nutrients including ammonia/ammonium. Personally, I would stop adding ammonia, do a few water changes, and add some fish. We can advise which if you indicate the intended species; it is not a problem of "cycling" issues with the fish, but one of tank maturity; some fish are better in newer tanks than others.
Puyallup is on the coast side of the Rockies, so I would assume your water is much the same as Plaamoo, and mine (I am up in the Vancouver, BC area which also has very soft water). My GH and KH are next to zero. I do not mess with buffers, as I have all soft water fish. It makes life much simpler.
