Important note:

When you first use a bubble stone (especially a 26-41cm bubble stone), if you find that only a few places have bubbles, please do not worry, this is a normal phenomenon.  Please keep the air pump and bubble stone working continuously, more and more bubbles will emerge.  According to actual testing, it takes approximately 3 days of continuous operation in water for the bubble stone to reach its optimal state.

If you encounter any problems during the installation and testing process, please contact our customer service personnel through a conversation, and we will provide you with one-on-one guidance.

Why do fish tanks require an oxygen supply system?

1. Increase the dissolved oxygen in water to avoid oxygen deficiency in fish.
2. Helps the growth of aerobic bacteria such as nitrifying bacteria.
3. Inhibiting the growth of anaerobic bacteria such as mold and preventing the occurrence of fish diseases such as water mold.
4. When a fish is sick, it needs to provide a lot of oxygen to help the fish recover.

Aquarium oxygen kit includes:

1. Bubble Stone: The bubbles are delicate and there is no bubble noise, and the bubble stones come in various lengths of 11cm/16cm/21cm/26cm/31cm/36cm/41cm.
2. Silent Oxygen Pump(optional): You can choose a silent air pump with corresponding voltage and plug according to your region.
3. Air tube: Standard size trachea with an inner diameter of 4mm.
4. Check Valve: When the air pump is below the water surface of the fish tank, a check valve is required to prevent the water in the fish tank from flowing back into the intake pump when the air pump is turned off.
5. Control Valve: The number of bubbles can be adjusted by adjusting the control valve.
6. Square Bent: When the air tube is bent at 90 degrees, it hinders air transmission, and a square bent can effectively solve this problem.
7. Air Tube Suction cup: The suction cup is used to fix the air tube, keep the fish tank clean, and can also be used to fix electrical wires.

Please note:

If you find that there are no bubbles or fewer bubbles after installation, please make adjustments according to the following methods:

1. Before installation, please ensure that the bubble stone is soaked in water for sufficient time (over 30 minutes), which is crucial for generating bubbles.
2. When you first use a bubble stone (especially a 26-41cm bubble stone), if you find that only a few places have bubbles, please do not worry, this is a normal phenomenon.  Please keep the air pump and bubble stone working continuously, more and more bubbles will emerge.  According to actual testing, it takes approximately 3 days of continuous operation in water for the bubble stone to reach its optimal state.
3. Please check if the installation direction of the check valve is correct.  The check valve can only provide one-way ventilation.  If the direction is incorrect, it will cause gas to not be transmitted to the bubble stone.
4. Please check if the regulating valve is fully closed, as gas will not be able to be transmitted to the bubble stone at this time.
5. Please check if the regulating valve is excessively open.  At this point, gas will leak out from the nut of the regulating valve and cannot be transmitted to the bubble stone.
6. After installing the bubble stone, turn on and off the air pump multiple times. When the air pump is turned off, there will be water flowing back into the pipeline.  Opening the air pump again at this time will make the bubble stone have a better effect of producing bubbles.

If you encounter any problems during the installation and testing process, please contact our customer service personnel through a conversation, and we will provide you with one-on-one guidance.

Silent Oxygen Pump

1. With advanced air compression system and shock absorption system, with multi-stage silencer design, the air pump has little noise.
2. Using special synthetic rubber component, constant pressure and gas volume.
3. Two versions:EU plug and US Plug

4. Two powers: If you want a soft and quiet bubble effect, choose a 3W air pump. If you want rich and violent bubble effect, 5W air pump is more suitable for you. For 26/31/36/41cm bubble stone, especially 36/41cm bubble stone, we recommend you to use 5W air pump.











EU plug region:


Korea, Russia, Peru. EU countries such as Germany, France, Netherlands, Denmark, Finland, Norway, Poland, Portugal, Austria, Belgium, Hungary, Spain, Sweden, etc. 

US plug region:
Countries such as the United States, Canada, Japan, Brazil, the Philippines, Thailand, etc.

Bubble Stone:

- The bubbles are delicate and there is no bubble noise.
- Using super hard gold steel sand, after high temperature sintering, good gas diffusion, good filterability, ozone resistance, corrosion.
- Increase oxygen levels, lower CO2 and raise PH, creates water currents.
- For long-term use, if there is dirt blockage, and the bubbles is reduced, please take it out of the fish tank and wash it.
- The air stone can be used repeatedly.
- The bubble stones come in various lengths of 11cm/16cm/21cm/26cm/31cm/36cm/41cm.
- Soak in water for 15 minutes before use.









If equipped with a high-power air pump(Over 5W), bubble stones can produce an astonishing amount of bubbles.

The function of the check valve

Check valves can ensure one-way flow of gas and liquid in the pipeline.

1. When the position of the air pump is lower than the water level line of the fish tank, a check valve must be used. Otherwise, when the power is turned off or the power is cut off, the water in the fish tank may flow back into the air pump through the air pipe, causing the air pump to malfunction.
2. When the position of the air pump is higher than the water level line of the fish tank, a check valve may not be used.
3. For safety reasons, regardless of whether the air pump is at or below the water level line of the fish tank, we recommend that you install a check valve to prevent unexpected situations (such as moving the air pump and forgetting to move it back to its original position when cleaning the fish tank).
