FAQ Questions: 


1. What is a porous air diffuser?

A porous air diffuser is a device that introduces air into a liquid, typically in an aquarium or aquaculture system. It helps to increase the oxygen levels in the water, which is essential for the health and well-being of aquatic plants and animals.


2. How does a porous air diffuser work?

A porous air diffuser releases small bubbles of air into the water through a series of small holes or pores. The bubbles rise to the water's surface and release their oxygen, which is then absorbed by the plants and animals living in the aquarium or aquaculture system.


3. What are the benefits of using a porous air diffuser?

There are several benefits to using a porous air diffuser, including the following:

1.) Improved oxygen levels: By releasing small bubbles of air into the water, a porous air diffuser helps to increase the oxygen levels in the water, which is essential for the health and well-being of aquatic plants and animals.

2.) Quiet operation: Porous air diffusers tend to be much quieter than other air pumps, making them ideal for use in sensitive environments such as hospitals or office buildings.

3.) Low maintenance: Porous air diffusers are easy to clean and maintain, making them a convenient and hassle-free option for aquarium and aquaculture enthusiasts.


4. What types of aquariums or aquaculture systems are porous air diffusers suitable for?

Porous air diffusers suit many aquariums and aquaculture systems, including freshwater, saltwater, and reef tanks. Because they can use to provide oxygen to both plants and animals and are suitable for use with a variety of different species.


5. How do I install a porous air diffuser in my aquarium or aquaculture system?

To install a porous air diffuser in your aquarium or aquaculture system, follow these steps:

Choose a suitable location for the diffuser, such as near the surface of the water or in an area with a good flow of water.
Connect the diffuser to an air pump using an airline hose.
Place the diffuser in the water and position it according to the manufacturer's instructions.
Turn on the air pump and adjust the flow rate as needed.


6. How do I maintain a porous air diffuser?

To maintain a porous air diffuser, follow these steps:

1.) Clean the diffuser regularly by rinsing it in clean water and removing debris or buildup.

2.) Replace the diffuser if it becomes damaged or no longer functions properly.

3.) Check the diffuser regularly to ensure that it works properly and that the airflow is consistent.

4.) Follow the manufacturer's instructions for any additional maintenance tasks that may be required.


7. Can I use a porous air diffuser with a CO2 system?

Yes, you can use a porous air diffuser with a CO2 system. However, it is important to carefully monitor the CO2 levels in the water to ensure that they do not become too high, as this can harm aquatic plants and animals.


8. How long do porous air diffusers last?

   The lifespan of a porous air diffuser will depend on several factors, including the quality of the diffuser, the amount of use it receives, and the maintenance it receives. Porous air diffusers can last for several years3-8 years )with proper care and maintenance.

    Porous air diffusers, also known as air stones or diffusers, can last for varying lengths of time depending on several factors, such as the type of material they are made of, the size of the diffuser, the water quality, and how well they are maintained.

    Generally, porous air diffusers made of high-quality materials and maintained properly can last for several years. However, over time, they can become clogged with algae, mineral deposits, and other debris, which can reduce their efficiency and lifespan. Regular cleaning and maintenance can help prolong their life.

    It's also worth noting that some types of porous air diffusers are designed to be disposable and may only last for a few months before needing to be replaced. Always refer to the manufacturer's guidelines for recommended usage and maintenance to ensure the longest possible lifespan for your diffuser.


9. Are porous air diffusers expensive?

The cost of a porous air diffuser can vary depending on the product's size, brand, and features. Porous air diffusers are generally inexpensive compared to other air pumps and oxygenation systems. 


10. Can porous air diffusers be used in outdoor ponds?

Yes, porous air diffusers can be used in outdoor ponds to increase the oxygen levels in the water and improve the overall health of the pond ecosystem. It is important to ensure that the diffuser is properly protected from the elements and that it is positioned in an area of the pond where it will be most effective.


11.  Air Diffuser vs Air Stone ? 


        A:  What is different with Air Diffuse vs Air Stone ? 

       For this questions, firstly, you need to know What is Air Diffuser and What is Air Stone ?

       What is Air Diffuser? 

      simple to say, Air Diffuser is used to fill the air in a room with tiny, breathable particles of beneficial

essential oils—giving the room a calmer, more pleasant-smelling ambiance. “It's well known that scent

is associated strongly with memory,” says Benjamin. 


        What is Air Stone ? 

An air stone is also known as an aquarium bulble. It is one of the most important pieces of furniture in

an aquarium. The basic function of an air stone is to supply dissolved air (oxygen) in the aquarium or fish tanks.

Air stones are usually made up of porous stones or lime wood. These small, inexpensive devices efficiently

diffuse air in the water and eliminate noise. They also prevent large bubbles, a common sight in most

conventional air filtration systems.

FeatureAir DiffuserAir Stone
Material Stone, ceramic, wood, synthetic Porous stone or mineral
Shape and Size Various shapes and sizes Typically small and round
Bubble Size Can produce various bubble sizes Typically produces fine bubbles
Primary Function Increase oxygen levels, improve water circulation Increase oxygen levels, improve water circulation
Maintenance Varies depending on the material May require regular cleaning to prevent clogging
Durability Varies depending on the material and maintenance May require replacement if clogged or degraded
Usage Aquariums, ponds, hydroponic systems Aquariums, ponds, hydroponic systems


But Nowadays, because of the porous metal filters application, people have started to use stainless steel

porous elements to make to be air stones to diffuser oxygen to water because the sintered metal air stone

can produce uniform and smaller bubbles, which help oxygen to be more integrated into the water and

help the plants and animals in the water to grow better.


So if you are also in the aquarium industry or Aquaculture, we introduce you can try our new technology,

which will help you to make your baby finish grow better.


Air Diffuser vs Air Stone? 

As you checked, it is actually different products, and different application. 

Air Diffuser is for air, and Air Stone is for gas / oxygen sparger in water.
