What is an aquarium bubbler?

An aquarium bubbler is a small device that is attached to an air pump. There is an electromagnet in the pump that generates vibrations in a rubber membrane in the bubbler.

The vibrations cause air to move in and out of the bubbler. It pushes the air into the water, where it creates bubbles and movement.

What's the point of an aquarium bubbler?

Aquarium bubblers provide your tank with additional oxygen by moving the surface of the water and allowing oxygen to enter the water column.

Many hobbyists use an aquarium bubbler to enhance the look of their tank by creating a curtain of shimmering bubbles, often on the back wall of the tank.

It is not essential to have a bubbler to supply oxygen to your aquarium. Many canister filters and HOB filters contain outflow devices such as bowls and spray bars that agitate the surface of the water enough to provide oxygen to the water. However, if you are keeping a frog, crab, shrimp, or newt, then you need oxygenated water very well, so an air bubble becomes a necessity.

Air stones versus bubble sticks

Aquarium bubblers usually come in two forms; Air stones and bubble sticks. Both devices have a similar effect on the aeration of the water in your tank. However, they create different effects and are often made from different materials that can affect the type of aquarium bubbler you choose for your tank.

Air stones

Air stones are usually made of blue, porous stone or limewood that allows air to flow through, which enters the tank as a mass of tiny bubbles.

Air stones come in many shapes and sizes. They can be used in isolation or in combination and are linked together by a series of ports and valves that allow you to regulate or redirect the airflow and bubble effect.

Bladder rods

Bubble rods are usually a piece of flexible tubing that contains numerous perforations through which air escapes into the water to create bubbles.

The great thing about bubble wands is that you can bend and shape them to create the visual effect you want, from bubble curtains to interesting patterns and shapes. Some bladder sticks also offer you LED connectivity so you can enjoy colorful effects in your tank.

What Are The Benefits Of Using Aquarium Bubblers?

Aquarium bubblers have three main advantages.

Water oxygenation

The main benefit of using an aquarium bubbler is that it provides oxygen to the water by moving the surface of the water and promoting better gas exchange.

Improved blood circulation

The increased surface movement also improves water circulation in the aquarium, which allows more water to be drawn through the filter system and keeps the tank clean and hygienic for your fish.

This extra circulation helps prevent dead spots where water stagnates and harmful bacteria can enter, causing a foul odor and a health risk to your fish.

Decorative appearance

Bubblers come in different shapes and designs. You can create decorative effects in the aquarium very effectively and at the same time aerate the water.

You can buy a wide variety of tank decorations that also double as aquarium bubblers. Children love these armor ornaments, especially deep sea divers, movie characters, sharks and the like. If you find this type of ornament a bit sticky, there are plenty of resin rocks, seashells, and fake corals to choose from too.

Disadvantages of aquarium fountains

There are a few disadvantages to using aquarium bubblers:

Additional costs and maintenance

Running an aquarium bubbler clearly incurs additional costs, although you don't have to turn it on around the clock.

A significant amount of maintenance is required to keep an aquarium in good condition. If you decide to install an aquarium bubbler, know that you will need to clean it from time to time to prevent the air holes from becoming clogged with algae and general litter.

Visible bubbles

While air bubbles look beautiful when used to create a curtain or other effect in your tank, not everyone appreciates the aesthetics. Some hobbyists want the fish they keep to be the stars of the show, and the bubbles can be seen as a distraction.

So if you'd rather enjoy the serenity and grace of your fish swimming silently in a beautifully aqua-masked aquarium, an aquarium bubbler may not be for you.

Salt creep

If you're holding a sea or reef tank, you're familiar with salt crawling. Salt creep can be aggravated by aquarium bubbles and air pumps.

When the bubbler creates bubbles, it moves the water, increasing the flow and movement. Air pumps also produce bubbles that will burst and splash water all over the place.

Unfortunately, all of this activity can cause the water to come into contact with surfaces in the tank that are not normally affected. When the water dries, it leaves a layer of salt crystals that looks very unattractive and causes undesirable extra maintenance for the hobbyist.

Bubblers can be loud

Most aquarium bubblers are quite noisy, and that is quite off-putting to many people, especially if the tank is in an office setting, classroom, bedroom, or living room with a television.

While the air pump itself may only make a small hum, the bubbles can make a reasonable noise and destroy the peaceful, stress-free environment the aquarium was designed for.

Can pollute sensitive fish

Some species of fish, like Bettas, come from environments where the water is still or even stagnant. These species can get stressed easily if placed in a tank where the water is very lively. Stress can affect the fish's immune system, leaving them open to attack by bacteria or parasites.

Therefore, do not insert an aquarium bubbler into a tank that contains fish or invertebrates that originate from still waters.

Final thoughts

An air bubble can be used to increase the oxygen content of the water in your aquarium, improve water circulation and add a spectacular special effect.

Remember that an aquarium bubbler requires some maintenance and will cost you a small amount of additional fuel. An aquarium bubbler should also not be used in a tank that contains delicate species of fish that naturally inhabit still water.
