Brine Shrimp Hatchery

This is a simple brine shrimp hatchery base for culturing brine shrimp for fish breeders.

Print it out and screw on a plastic 2 liter bottle with it's base cut off (see photo at left).

Once printed, I suggest brushing the inside with acetone to make it water tight. Optionally, add a rubber o-ring at the bottom of the threads to help seal it even more. Attach the airline from your air pump to the nipple protruding vertically from the hatchery base.

Make sure to use an airline check valve in case of a power outage as one does not want the water in this hatchery to back flow into the air pump.
