Size: 2″ diameter air diffuser

If you feel that your aquarium can do better with more dissolved oxygen, then you should get the Hygger Aquarium Air Stone Kit Round Air Disk. This disk-shaped air stone is designed specifically to increase oxygen saturation inside your aquarium. The disk surface serves as a diffuser, releasing bubbles twice that of a regular air stone.

The device is only 2 inches in diameter but weighs 150 grams, which means you won’t have to worry about it floating around inside the tank. It even comes with a suction cup so that you can attach it to the sides of the tank. Its discreet design will make it blend with the background and won’t disrupt your aquascape at all. As recommended by the manufacturer, a 2W air pump should do well for this model.

The Aqueon Flexible LED Bubble Wand is a quick solution that will improve your aquarium’s aesthetics and provide more dissolved oxygen in the water. This wand is completely flexible at about a foot long and will bend to your desired shape.

You can hide it behind hardscapes and plants, bury it in the substrate, or display it where everyone can see it — wherever you install it, it will create the best ambiance for your fish tank.

Once you attach an air pump to the wand, it will create a beautiful raft of bubbles rising to the surface. The best thing about this wand is that it gives you the freedom to turn the colorful lights only, the bubbler only or both. A truly flexible option for any aquarium!

UPETTOOLS Aquarium Air Stone Nano Bubble Stone Kit

UPETTOOLS Aquarium Air Stone Nano Bubble Stone Kit with Control Valve #ad

Size: 1.38″ diameter

The tinier the bubbles, the more dissolved oxygen your aquarium gets. That’s no problem with the UPETTOOLS Aquarium Air Stone Nano Bubble Stone Kit. This disc air stone is only 60mm in diameter, but it’s suitable for tanks up to 15 gallons in capacity.

The air stone is attached to an L-shaped pipe and comes with two suction cups so that you can easily slide it inside the tank and stick it to the wall of your aquarium. With the package also comes a 2-way control valve, which protects your fish tank from back-siphoning.

This air stone kit produces a very dense foam of bubbles that results in a mesmerizing effect inside your fish tank.

Pawfly 4 Air Stone Bars

Pawfly 4 Air Stone Bars #ad

Size: 4.5 x 0.8 x 0.5″

This set of air stone bars from Pawfly is a must-have if you’re looking to add air stones to multiple tanks. With this option, you get four air stone bars with one purchase. Each bar is about 4 inches long and weighs 1 ounce each. The rectangular cuboid shape means this product can cover a much larger surface area than your regular air stone.

Each stone is designed to be stable and can easily blend in with the rest of your tank. These air stones produce medium-sized air bubbles and should be powered by an air pump with a capacity greater than 2.5 watts. Lower than that, and the bubbles produced will be very limited. Overall, this is a cost-efficient option and one you shouldn’t miss if you’re looking for a decent air stone that won’t break the bank.

The lights change automatically, and this combination of bubbles and light creates a fantastic underwater scene inside your fish tank. Keep in mind, though, that this fixture doesn’t come with a switch, so you will have to unplug it if you want to turn it off. The good thing is that it already comes with everything you need to install it, including suction cups to secure it in place and an air hose to connect to your air pump.

On the “roof” of the hideout is an air stone disc about an inch in diameter with six multicolored LED bulbs integrated into it.

When turned on, a chimney of bubbles rises from the disc, creating a “smoke” effect coming out of the hut’s “chimney.” The changing lights from the LEDs add to the awesome effect. And did we mention that the hut also serves as a shelter for small fish?

The amount and speed of the bubbles produced will depend on the strength of your air pump; just adjust the air pump to your desired preference.

Frequently Asked Questions about air bubblers

1. How do you use fish tank bubbler decorations?

Aquarium air stone and bubbler decorations come in different shapes and sizes, but the principle used to make them work is similar. These fixtures don’t come with an air pump, so assuming you have an air pump suitable for your aquarium, all you need is to attach it to the bubbler via an inlet. You may also need a control valve to regulate the flow of the air and the amount of bubbles according to your preference.

2. How do you clean an aquarium air stone?

Always abide by the cleaning guide provided by the manufacturer. Most bubbler decors are designed for easy maintenance and will only require soft brushing to remove the buildup of dirt. You can clean your air stone or bubbler every time you change the water in your aquarium for convenience.

3. Why is my air stone not working?

It’s common for air stones not to work the first time they are attached to an air pump. More often than not, the air stone will start working after a few minutes of being soaked in water. If you have an air stone that stopped working after a while, perhaps it’s already clogged and needs cleaning.

4. Where do I put the air stone inside the tank?

You can place your air stone anywhere inside the tank as long as it’s at the very bottom. This will ensure that the bubbles flow from the bottom up, covering as much area as possible. If you’re concerned about aesthetics, you should place the air stone behind live plants or hardscape, which will give your aquarium a more natural look.

5. How do you make a DIY aquarium air stone?

There are several ways to make your own air stone. One method involves a lava rock. Lava rocks are very porous and can make excellent air stones. Take a piece of lava rock large enough for you to drill a hole for the tubing, and you’re done. You can also use PVC pipes. Get a PVC pipe of your desired size and drill tiny holes on the side. Insert an air lining inside, and you have a DIY air stone. The only drawback of PVC air stones is that you can only go as small with the holes as the size of your smallest drill bit.
