Fishless Cycle : How often and how much food to add?

    Hello! Just a short and simple question : how often and how much food should I add to fishless cycling a 20g? Thanks!

    That's the problem with using food to cycle - there's no straight forward answer. Food does not decompose at a steady and continuous rate, and it's not a good source of ammonia for cycling for this reason.

    Using pure ammonia is much better as you can control how much is used for cycling.

    Thanks for your answer. Where can I buy the ammonia? Is there a particular brand that you'd recommend?

    You can find a jug at most hardware stores. Just be sure there are no surfactants in it (nothing other than ammonia, and when you shake it, it doesn't bubble).
