Different Types Of Aquarium Bubblers: Air Stones vs Bubble Wands

When considering the performance of Air Stones and Bubble Wands just know that their effect on the aeration of your water is about the same, neither would be considered superior over the others.

However, when it comes to the different materials they are made of and the effects they can produce you’ll have some thinking to do.

Air Stones

The Air Stone is usually made up of a small blue porous stone, and sometimes lime wood which allows air to be diffused into the tank as tiny bubbles.

Air stones typically don’t produce many effects however you can buy airstones in different shapes, sizes which can produce ver cool looking bubbe effects.

Bubble Wands

A bubble wand is typically a flexible piece of tubing perforated with a few holes that can be shaped to provide visual effects and curtains of bubbles in your tank.

When you use a bubble wand in your fish tank you can shape it to cause the bubbles to rise in different patterns which can make for an interesting background.

Lastly, some bubble wands may have the option for LED connectivity which will add another dimension of color effects to your tank.

Can You Use Multiple Bubble Wands In Your Aquarium?

Of course, some bubble wands can be attached to one another right in the aquarium. Or you can provide an airline tube splitter to allow air from your pump to be sent to two separate bubble wands.

What Does An Aquarium Bubbler Do?

An aquarium bubbler, which could be an air stone, air wand or even just an air tube placed in the water will “help” oxygenate the water as the bubbles create enough surface agitation to allow oxygen to enter the water column.

Does A Fish Tank Need A Bubbler?

No, all tanks do not require a bubbler. It’s true bubblers help oxygenate the water, but as long as you have sufficient surface agitation of the water your fish will be able to breathe. Many HOB filters and Canister Filter outflow devices like spray bars and trays will disturb the water surface sufficiently to allow the oxygenation of water to occur.

Can You Get Too Much Oxygen In A Fish Tank?

Yes, just like with too much Co2 too much oxygen can also be deadly to your fish. That said an aquarium bubbler is very unlikely to cause excess oxygen levels to occur.
