I'm not sure if he gave aeration recommendations or not, but I've been impressed with the amount of air these little guys put out. They will run for many hours on 2 AA batteries. There's a larger one that runs on D batteries that I imagine provides even more air volume, but have always preferred rechargeable AA batteries. At $5 each, these are cheap insurance and convenient to move from one container to another without wiring consideration.
