Note that there are a lot more products out there claim to do the same thing, but many of them don't really work because they have the wrong species of bacteria (land based). The land based bacteria will drown in the water eventually, it will result in the crash of cycle just when it seems to be done, and you'd have to keep dosing more to keep the "cycle". The three I mentioned above are proven working with the correct species of bacteria needed in an aquarium setting.
It seems you have picked the fish food as your source of ammonia. It can be done although it will be a lot slower than using pure ammonia. The live bacteria products can speed this type of fishless cycling too, especially at your current stage when you have only ammonia. Do you have DrTim's Aquatics Ammonium chloride for Aquarium? It is a form of pure ammonia made just for aquarium hobbyists.
As for other tips on speeding up the cycling, you can find most of them in the following article. Tips to speed up Aquarium cycling
To sum it up,
1. Get live bacteria for jump start
2. Raise the water temperature to middle/high 80F.
3. Increase oxygen level in the water by increasing surface water movement. ex: Adding an air stone.
I believe your tank is around 10 (US) gallon. It is a good size for a cherry shrimp tank. 10 of them is also a good number to start with.
