I'm personally not a fan of bacteria in a bottle, I don't think anything can take the place of a proper cycling of a tank, just my own personal opinion...BUT with that said. About 5 months ago I did have to set up a 29g in a hurry to house some fish and I used Start Smart Complete with pretty good results.
Do you have an existing tank running? if so then just seed it with some of the media from that and you'll be ready to go in a few days after seeding.
