The purpose is to keep the water moving inside the hatchery without damaging the brine shrimp. Brine shrimp need to be suspended in the water to hatch, and do not hatch well on the bottom. Make sure you have a valve, because almost any airpump will be too powerful for a brine shrimp hatchery without one. All you want to do is keep the brine shrimp from collecting on the bottom.
