Fine air stones produce minuscule bubbles, while rough ones produce larger bubbles. You need to choose something that's suitable to the type of fishes you're keeping inside the tank. If you're tending small and slow-moving fishes, for example, it's better to keep the bubbles small as the velocity of larger bubbles may impede the movement of the fishes.
I'm looking for the best air stones for my underground filter.
If the air stone is purely for decoration, then the shape is reallyup to you and your tastes. There are long air stones in varyinglengths, round ones in several sizes, square ones, rectangular ones,and a wide variety of other shapes and sizes - even ones that can bebent and shaped to what you want. When you're looking for an air stoneto use purely for decoration in your fish tank, there are manychoices. Just remember that these larger air stones will also requirea larger .
Air Pumps & Air Stones: Increase Aeration for Healthy Aquariums
Aeration within your aquarium is very important for your Betta. Even though a fairly large fish tank with a chosen by a professional provides plenty of aeration, it’s still wise to add further equipment. To be cautious, many hobbyists install an airstone that connects to an air pump. This provides a stream of bubbles that are not only good for the fish, but also provide a pleasing site in your aquarium.

Precisely how effective are those small bubbles which come out from air stones, or diffusers? A number of aquarists believe that they perform a crucial role inside the with regards to oxygenation and air diffusion of the water, and that this air source is sufficient. When it comes to the rise of DO (dissolved oxygen) in a fish tank, the water surface is one of the main sites where this exchange takes place. Oxygen is blended down into the water; carbon dioxide is released out to the air, not forgetting that other gases readily pass through the permeable surface of water at the same time. This is the principle which our bodies work on whenever we breathe; inhale good air and exhale bad air. It’s the same manner with the fish tank.I have to use an air stone in all of my tanks that have any fish. Why? I don't know. I run them 24/7 simply because I cannot seem to find an inexpensive timer that functions properly with an air pump, and I've spent so much money recently with respect to all of this--that I am just plain reluctant to spend $25+ (x ?) on a good, reliable timer. I will in the future, but right now I just feel the need to procrastinate for a while.Watch more How to Take Care of an Aquarium videos:
To decide if you need an air pump for your aquarium you want to look at the other pieces of filtration that you have and determine whether or not they are sufficiently providing oxygen for the aquarium.
I like air pumps on fresh water aquariums. They're great at supplementing oxygen into the water. Most fresh water filters don't do an adequate job at adding air or oxygen to the aquarium simply because they're cannister style or they're hang on and they just don't agitate the water enough to really push oxygen into the water. As your fish grow the oxygen demands are going to increase as the fish get bigger.
Also, when the water warms up in the summer the water has a lower capacity to hold oxygen, so an air pump is going to be very beneficial to add that extra air that's needed. Dissolved oxygen is very, very important to fish, to bacteria, and even to plants at night. Plants and algae need oxygen at night.
So air pumps are relatively inexpensive. They're pretty quiet nowadays. And I don't see any reason not to have one on a fresh water aquarium. Again, on salt water your filtration should be stout enough to not require the need for an air pump.
But, once you do go with an air pump, you want to make sure that it's installed properly. If you have your air pump located below the aquarium and the power goes out it's possible to create a back siphon of water through the aquarium line into the air pump, and it'll result in siphoning all the water from your aquarium onto the floor. You can avoid this by going with a very inexpensive two to three dollar check valve that will go inline on the air line from the pump to the air stone in the aquarium.
Other things to consider is the type of air stone. There's air stone that will produce fine bubbles and ones that will produce coarse bubbles. Depending on the needs of the aquarium fine bubbles will give you a little bit more surface area, and that's going to give you more oxygen. But sometimes they don't break up as easily and it'll result in water that looks a little bit cloudy.
So I like nice, thick, coarse bubbles, and four or six inch air stone works great. Put it behind a rock or a plant and it creates a very nice visual look to the tank while adding critical oxygen to the environment. And keep it on all the time. Keep it on 24/7.Air stones can be placed anywhere in a fish tank, there are almost no limitations as to position and numbers of used devices. The device is connected to the air pump via airline which makes it possible to pump air from outside through the pump to the air stone. There’s a motor which drives propeller that sucks air which is then pumped to an air stone. As an aquarium air stone is a lightweight device which is full of little holes intended for displacing air into the water, air is being released into an aquarium once the pump is plugged into electricity and turned on.
