Different Types Of Air Stones 

Air stones are often produced in many different shapes and types. Each of them will have its characteristics to suit each person’s needs and aquarium.


This type can be made from stone, ceramic, or wood. Its design is quite simple, like a cylindrical block, a square box, or a long rectangular bar.

One end of these stones will be a hollow tube to connect to the air duct. Their bodies will include many tiny holes to create a cascade of bubbles when you turn them on. 

The main feature of this classic is its compact and ergonomic design. You can easily put it in the corner of the aquarium without taking up a lot of space. At a low price, classic air stones are available in most aquarium specialty stores.

Bubble Wand

Bubble wand also has a fairly simple design and doesn’t take up much space in your aquarium. Hence, it remains an ideal choice for you regardless of the size of your fish tank.

In addition to the frame with ventilation holes, the bubble wand also has a base for fixing. Therefore, you can easily place it inside or on the tank’s wall.

Unlike the round disc and classic air stone, the bubble wand doesn’t produce steady streams of air bubbles. The outcome will be bubbles with different sizes and densities.

Round Disc

If you have a large aquarium, this round dish type is worth considering. It can perform with a higher capacity than the others on this list. 

Its shape like a small round disc with one surface is the base; another surface contains many air vents. After being connected to the air duct, they will create a large and stable microbubble flow.

The contact area of ​​the surface with water is quite large. Therefore, you clean them regularly, avoiding clogging that reduces performance and causes pollution.

Bubble Ornaments

For those who want to upgrade and decorate their aquarium, bubble ornaments are the ideal choice. With a variety of designs and shapes, they will suit each of your styles and needs.

Compared to the rest, bubble ornaments have slightly worse performance. They will do a better job of decorating and beautifying the aquarium than providing oxygen for your fish.

As usual, these products will cost you higher than other types. Their prices will be dependent on design, size, brand, and so on.

Buying Guide

Certainly, we listed out some criteria to rank the products and choose the top 10 best overall. There are four angles that you should pay attention to before making a final decision.

Appearance And Efficiency

How would you like to have air stones? This question is very important because it will also somewhat affect the aesthetics of your aquarium.

Many people don’t really care about anything but the performance. In this case, appearance isn’t important. So classic air stones, round disks, or bubble wands are all acceptable.

Still, if you’re looking for the one that enhances your tank’s beauty, choosing carefully is necessary. The best option is the bubble ornaments that come in different designs that you  choose.

About the efficiency, you have to check this feature carefully. Many products, despite the enticing appearance,  deliver extremely bad performance. The outcome is a low density, and a weak bubble stream isn’t a great choice.

Build Quality

Ensure the product you choose can work well for three to six months. Of course, no one wants to buy air stones and throw them away after a few days of use.

The parts should be carefully assembled. Most cheap products are prone to being quite loose and easily damaged by a strong force.

It’s advisable to check the ventilation holes on the surface of the air stones. If they are clogged or too small, sometimes the bubble flow won’t be what you expect.

Size And Shape

Depending on the size of the fish tank, you can choose suitable air stones. An air stone that is too small won’t have enough capacity to supply oxygen to a large aquarium. Vice versa, too large air stones will take up many areas of ​​a small aquarium.


You shouldn’t buy a product that is over-budget. As you will have to replace air stones every six months to a year, purchasing an affordable one is always the best choice.

As usual, air stones can cost from one dollar to more than ten dollars for each. A tip that you can apply to save more money is to buy a set or kit.


For those buying air stones for the first time, there will be a lot of confusion. That’s why we’ve listed three of the most frequently asked questions and detailed answers that will be super supportive to you.

How To Clean The Air Stones?

The biggest problem with cleaning air stones is that the surface has a lot of air holes, which are difficult to clean completely and very easily clogged.

Step 1: Rinse and scrub: The first thing you need to do after removing the air stones from the air duct is to rinse them with water and scrub lightly. This one will help remove algae clinging to the outside of the rock for the next steps.

Step 2: Boil for 10 minutes: Boil the stones in water over low heat for about ten minutes to push the stain. Then, take them out and let them cool a bit before continuing.

Step 3: Soak in cleaning soap or conditioner: We can use bleach diluted with water in the 1:3 ratio. Soak your stone for 24 to 48 hours, depending on the condition of the stones.

Step 4: Rinse carefully again: Ensure you remove all bleach, soap, or any other detergent at this step. Because if not, it will probably affect the fish when you reinstall the air stones into the aquarium.

Step 5: Let them dry: The final step is to leave them completely dry. This step helps to avoid moldy, like when you put it right into storage while it’s still damp.

How To Install Air Stones?

For those who don’t know how to install air stones, you can follow these simple steps:

  • Connect air stone with the air pump
  • Choose a stable place in the aquarium to place the air stones. You can also attach them to the tank wall
  • Start the air pump and check the airflow. Watch the outcome of bubbles that air stones deliver
  • If the air stones do not produce air bubbles, check the air ducts or air holes on their surface.
  • After that, let them do their tasks.

Where Should I Place The Air Stones In A Water Tank?

Air stones can be placed anywhere in the aquarium you want. The important thing to note here is the convenience of connecting to the air pump and the bubble distribution area.

You can place them in the tank’s corner to facilitate connection to the air pump. The center is a great choice for air stones with high bubble density. For modest-sized aquariums, people often attach them to the wall of the tank to save space.
