DIY Fish Feeder
- 1). Twist off the top of a 2-liter plastic bottle. Drill two 0.9-inch holes in the top section of the bottle, no more than 6 inches apart and within a straight line of one another.
- 2). Insert a 2-inch piece of plastic pipe that is 0.8 inches in diameter into the first hole.
- 3). Squeeze a pea-sized amount of silicone sealer onto your index finger. Spread the silicone around the hole and 2-inch plastic pipe; spread enough silicone to form a watertight seal.
- 4). Insert a second 2-inch pipe piece into the second hole. Spread silicone to where the pipe meets the hole with your fingers; ensure that enough silicone coats the area. Allow the silicone to harden for at least 20 minutes.
- 5). Cut a 3-foot long piece of airline tubing, with a metal box cutter. Slice the tubing into a 2-foot long piece. You will have a 1-foot piece left over, which you will use.
- 6). Put the free end of the 2-foot long piece into your aquarium. Place the other end over the 2-inch plastic pipe sticking out from the hole.
- 7). Connect the 1-foot-long airline tube to the other 2-inch plastic pipe. Attach the free end onto the exhaust nozzle of a vibrator air pump.
- 8). Plug the vibrator pump into a 24-hour mechanical timer and insert the mechanical timer's power plug into a wall socket. Do not turn on.
- 9). Fill the 2-liter plastic bottle halfway with aquarium water. Add live brine shrimp into the 2-liter bottle.

Place the bottle cap onto the bottle and screw tight. - 11
Turn the 2-liter plastic bottle upside down. Secure the bottle within a wall-mounted holder, directly above the aquarium. - 12
Check that the feeder is functioning properly, by turning on the vibrating pump. Air from the pump should immediately flow into the bottle, pushing water and brine shrimp through the tube. The process will take time -- the brine shrimp will slowly find their way through the airline tubing and into the aquarium, becoming quick meals for fish. - 13
Set the 24-hour mechanical timer to run at 15 minutes intervals each hour. Observe the 24-hour mechanical timer to ensure it is working properly. Watch for the brine shrimp to travel through the airline tubing and into the water. Fish will migrate to the area and begin feeding.
