What type of Ammonia for fishless cycle?

I've been using the Wal-Mart brand (97 cents/bottle). It's just ammonia and water, and there's no foaming when I shake it!

I'll look for a walmart though I have no idea where the closest one is. I just want to start this darn cycle, my tank has been sitting there with water and the filter running for 5 days now!
 
Ace Hardware: Janitor Strength Formula. Just has ammonium hydroxide and water.
 
if you dont want to look for ammonia, sprinkling fish food in works well instead!

Really? This will produce as much ammonia as just pure stuff? I have guppy food (flakes + freeze dried blood worms) and frozen blood worms. What would work best and ~how much would I add to a 10g?
