DIY Brine Shrimp Hatchery
Now you can hatch your own brine shrimp from eggs for fresh food for your saltwater fish and invertebrates for just a few pennies per day.
Here is an inexpensive, easy to make DIY Brine Shrimp Hatchery which can be constructed in less than 20 minutes. It utilizes one (or more) 2-liter plastic soda bottles, an air pump, and 3/16" plastic air hose.
The true beauty of this design (other than the fact that is so cheap) is that it is so easy to use. The brine shrimp can be hatched out, then drained out (no more tedious siphoning) into a brine shrimp net, leaving the unhatched eggs and egg casings behind. The brine shrimp can then be rinsed and put into either another brine shrimp hatchery for further growth or stored for feeding to your livestock.
Here is a schematic of what the DIY Brine Shrimp Hatchery looks like.Continue to 2 of 3 below.

How to do it:
- Cut the bottom off of the soda bottle.
- With the 3/16" drill, drill 4 holes, equally spaced around the bottle, 1" down (if the bottle is inverted) for the hanging strings.
- Drill a 3/16" hole in the center of the bottle cap.
- Insert the 2'' piece of 3/16" rigid tubing into the cap, so that it will be sticking into the bottle about 1". Silicone the rigid tubing in place.
- Cut 2 equal length pieces of string (about 12" should be about right).
- Tie one end of each piece of string through one hole and tie the other end to an "S" hook.
- Insert one end of the 3/16" hose over the rigid tubing in the bottle cap and screw the cap on the bottle.
- Insert the other end of the tubing over the air pump fitting.
- Loop the strings over your horizontal hatchery hanger and insert the "S" hooks through a hole in the bottle on the other side, making sure that the air pump is above it.
- Fill with saltwater to the waterline (see graphic, above).
