Aquarium Air Pumps & Airstones (Create Bubbles in Aquariums)

Aquarium air pump in a tank

Creating bubbles using aquarium air pumps and airstones maintains proper water oxygen levels in the tank. This improves the overall health of your fish and other aquatic life.

Not only do they ensure adequate oxygenation but also contribute significantly towards stable water conditions by promoting efficient gas exchange at the water surface.

This guide will provide an in-depth analysis of air pumps and airstones, how to connect them to other equipment, and alternative bubble makers for your consideration.

Read on as we dive into the world of air pumps and airstones.

What Are Aquarium Air Pumps?

Aquarium air pumps are devices used to increase the oxygen levels in an aquarium by circulating the water and promoting gas exchange at the surface.

They’re essential for maintaining a healthy environment for aquatic life, particularly in fish tanks with low water movement or limited surface area.

Air pumps work by pushing air through the air-line tubing connected to air stones, bubble wands, or other diffusers placed inside the aquarium.

As the air is released underwater, it creates bubbles that rise to the surface, increasing water agitation and oxygenation.

Air pumps can power filters, airstones, and several types of plastic decorations.

It’s recommended to place the air pump above the midpoint level of your aquarium or incorporate a checkvalve into your air-line tubing.

This small yet essential device allows water or air to flow in only one direction within the air-line tubing.

Thus, it protects the air pump from water backflow damage if electrical power is lost.

Here are some benefits of using an aquarium air pump:

  1. Improved oxygenation: Increased oxygen levels help maintain the overall health of fish and other aquatic organisms.
  2. Better water circulation: Air pumps help prevent stagnant areas in the tank, ensuring a more uniform distribution of heat, dissolved oxygen, and nutrients.
  3. Aesthetics: Air pumps can be used to create visually appealing bubble displays or to operate decorations and ornaments.
  4. Supports filtration: In some setups, air pumps drive sponge filters or undergravel filters, which provide biological filtration.

What Are Aquarium Airstones?

Airstones are small tube-shaped artificial stones that split the air supplied by an air pump into small bubbles.

These tiny bubbles then rise to the surface of the water, promoting gas exchange between the water and the atmosphere.

This process ensures that your aquatic friends have enough dissolved oxygen to thrive.

There are various varieties of airstones for you to choose from:

  1. Material: Airstones are made from ceramic or perforated wood-based materials.
  2. Shape: They can come in different shapes such as short and round or tall and thin.
  3. Bubble size: Tall airstones generally emit a finer stream of bubbles than shorter ones.

To use an airstone, simply attach one end of the standard air-line tubing to it and connect the other end of the tube to your air pump.

Replace the airstone when it gets clogged.

Proper maintenance and timely replacement will ensure optimal performance from these small devices in your aquarium setup.

What Other Bubble Makers Are Available?

Besides the classic airstones, 3 alternatives to create bubbles in an aquarium are:

  1. Bubble disks,
  2. Bubble curtains, and
  3. Bubble wands.

Bubble disks resemble plastic flying discs connected to an air pump with tubing.

When placed in the tank, they create a large stream of bubbles that fish enjoy swimming through.

However, they may get clogged with algae over time and need gentle rinsing under clear water for maintenance.

On the other hand, bubble curtains are long devices emitting small columns of bubbles all along their surface.

Many come equipped with color-changing LEDs for added drama.

Keep in mind that while these options can be visually appealing, they might not be as durable or low-maintenance as traditional airstones.

A bubble wand is a long, rod-shaped bubble-making device with suction cups for mounting on glass.

They’re used to create streams of bubbles in the tank. However, bubble wands can get clogged and stop functioning quickly, break easily, and may need heavy objects to keep them submerged.

It’s recommended to avoid bubble wands as they often malfunction after a short period of use.

How to Connect Air Pumps to Other Equipment?

Now that you’ve learned about air pumps and airstones, it’s time to explore how to connect these essential components to other devices in your aquarium.

So let’s dive into the details of connecting your air pumps to other equipment using tubes, valves, and tees.

1. Air-line Tubing

When it comes to air-line tubing, opting for the rubber type made from silicone or rubber-based materials is definitely a smart move for your aquarium setup.

This type of tubing is not only more flexible and easier to work with, but it also boasts a blue-green color that blends in nicely with the natural tint of aquarium water.

Rubber tubing is pliable, making it simple to maneuver around decorations without cracking as it ages.

Also, unlike older standard clear tubing that you might find at local pet stores, rubber tubing doesn’t turn yellow or bend out of shape when set over equipment connections.

In addition to choosing the right material for your air-line tubing, consider factors such as length and diameter.

Most tubing has a standard diameter; however, mini tubing with connectors may be necessary for some aquarium decorations that have extremely small connections in the back.

To keep your tubing securely in place within your tank, you can purchase air-line suction cups that attach to the inside of the aquarium glass.

These handy accessories feature plastic clips that hold your air-line tubing firmly so that it doesn’t float around within the tank and disrupt its aesthetic appeal or functionality.

2. Gang Values and Tees

In addition to selecting the right tubing for your aquarium, you might also want to consider using gang valves and tees to efficiently split and control the airflow throughout your tank.

Gang valves are a great option for running multiple pieces of equipment or decorations off one air pump.

These valves typically hang on the back of the tank and are made out of either plastic or brass.

The air-line tubing from the pump connects to one side, while the other side has multiple outlets that can be connected to various decorations and equipment using tubes.

One key advantage of gang valves is that you can easily adjust the strength of each individual outlet’s airflow by turning their respective shut-off nozzles.

On the other hand, tees are useful accessories when it comes to splitting a single air source in two opposite directions.

Shaped like the letter T, they’re typically made from plastic or copper materials.

While tees don’t offer as many outlets as gang valves do, they still provide an inexpensive solution for dividing your air supply between two pieces of equipment or decorations.

However, keep in mind that gang valves are more suitable if you need adjustable airflow control and additional connections for numerous items within your aquarium.

Always Remember…

Air pumps and airstones work together to provide essential oxygenation and water movement to ensure your aquarium fish and plants thrive.

Take the time to choose the right equipment for your specific needs.

And connecting them properly will help you to create an optimal habitat for your aquatic friends and a thriving underwater ecosystem.
