How to Make Aquarium Bubblers

Things You'll Need

  • Air pump

  • Air tubing

  • Air stone

  • Exacto knife

  • Air tubing connector (optional)

  • Silicone aquarium sealant (optional)

Warning

The aquarium pump should be placed above the surface of the water to prevent water from flowing backward into the pump if the power goes out.

Tip

Multiple air stones can be used by adding a t-connector or y-connector to the air tubing. Secure the connector to the tube using silicone aquarium sealant. Allow the sealant to dry before placing the connector in the water.

Create a row of bubbles by using the Exacto knife to drill small holes along the length of the air tubing that will be under water. Block the open end of the tubing with silicone aquarium sealant. Allow the sealant to dry before placing the tubing in the water.

The fine bubbles caused by aerators increase the amount of oxygen available to aquarium fish.

Fish extract oxygen from the water to survive, just as humans extract oxygen from the air to breathe. One means of improving the oxygenation of aquarium water is through the use of a bubbler, also called an aerator. Even a simple bubbler will improve oxygenation by agitating the water surface, creating the exchange of oxygen and carbon dioxide in the process. Proper aeration also aids in controlling the water temperature in the aquarium.

Step 1

Select a safe location for your aquarium pump next to your aquarium. This location should be close to an electrical socket and above the surface of the aquarium water.

Step 2

Cut the air tubing to an appropriate length using the Exacto knife. You can approximate the correct length by holding one end of the tubing near the pump and extending it to where you want the air stone to rest inside the aquarium.

Step 3

Attach one end of the tubing to the air pump. Make certain that it fits securely over the nozzle and is free of cracks or splits.

Step 4

Attach the opposite end of the tube to the air stone. Ensure that the tube is secure and is free of cracks or splits before dropping it into your aquarium.

Step 5

Place the air stone in the water. The air stone can be secured in place by placing the tubing under gravel, by placing the stone into a decoration or by using a hanger.
