I allow my tanks to grow in for a minimum of 4 weeks, sometimes longer. Like Amy said, it gives you time to tweak the tank out and it also allows the bio filter to cycle, just like an aquarium. The other benefit to giving the added time is it allows the microfauna to establish themselves and start to multiply before you put some killers in the tank lol
