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.

We enjoy keeping fish, and have for many years. We are trying to promote the hobby as much as possible. We want to see many others succeed in their fish keeping efforts and are committed to sharing our knowledge when we can.
