- 1). Drill two holes, 0.9-inch diameter, next to each other in the top of a one-quart plastic bottle. Place the first two-inch piece of rigid 0.9-inch diameter pipe into one of the holes.
- 2). Use a pea-sized amount of non-toxic, 100 percent silicone sealer to form a watertight seal around the entry hole. Smooth the silicone out with your finger.
- 3). Place the second two-inch piece of rigid 0.9-inch diameter pipe into the remaining hole. Use another pea-sized amount of non-toxic, 100 percent silicone sealer to form a watertight seal around this entry hole. Smooth the silicone out with your finger. Allow the bottle top and silicone to cure for at least a day.
- 4). Pour a small volume of boiling water into the bowl and place one end of the two-foot piece of air line tubing into the bowl.
- 5). Push this end of the two-foot long piece of air line tubing over the end of one of the two-inch long pieces of rigid 0.9-inch diameter pipe. Place the opposite end of the one-foot long piece of tubing into the aquarium. Place one end of a one-foot piece of air line tubing into the bowl of boiling water.
- 6). Push this end of the one-foot long piece of air line tubing over the end of the second two-inch long piece of rigid 0.9-inch diameter pipe. Attach the opposite end of the one-foot long piece of tubing to the exhaust nozzle of your vibrator air pump.
- 7). Plug the electrical timer into a wall power source, but do not turn it on yet. Plug the vibrator air pump into an electrical timer.
- 8). Pour aquarium water to the halfway mark in the one-quart bottle. Add 200 to 300 living brine shrimp to the bottle. Replace the top on the bottle and ensure that it is fitting tightly.
- 9). Invert the one-quart bottle and position it carefully in the wall mounted bracket, just above the aquarium. Set the electrical timer to run for a maximum of 10 minutes every hour. Set the electrical timer to run only during the time that the aquarium light is on.

Turn on the wall power supply. Air from the vibrator air pump will slowly fill the bottle and displace water and brine shrimp into the aquarium, throughout the day.
