What Does An Air Stone Do For My Aquarium?
An air stone is a not a rock as the name implies. They can often be made out of some kind of mineral, but they are not actually rocks as we know them. They are stones made of very porous materials with lots of miniature holes. Air stones are connected to air pumps which pump air through them. The very porous material then diffuses the oxygen, creates really small bubbles, and saturates the water with these bubbles.
So, what is a air stone for in a fish tank?
In essence, the point of an air stone is to increase the level of oxygen in the water in order to aerate it. In other words, these stones help fish breathe much better in the water. This oxygenation also helps to create a gentle flow in the aquarium in order to get the water moving around so if you are wondering “are air stones good for aquariums?”, the answer would be YES.

Different Types Of Air Stones
There are a few different types of air stones out there, so let’s talk about each of them real quick.
There are air stones made out of compacted sand. These work just fine in terms of aeration, plus they are all natural, but they do tend to crumble and deteriorate over time.
There are many different air stones made out of various pressed or unprocessed minerals. These may not aerate the water as well as sand air stones, but they also do not crumble as quickly.
There are a few different air stones made out of porous wood like limewood. These work pretty well, but they do degrade due to water damage.
Some porous stones are used for air stones. These also work quite well, but may not have as much of an oxygenation effect as other options.
There are various air stones made of synthetic materials such as ceramic or fiberglass. These tend to be very durable and long lasting, they are often washable, they don’t degrade much under water, and they are designed for maximal oxygenation.
Some air stones are made of glass beads. Glass is not the best for creating a thick wall of bubbles, but it does last for a really long time.
