As shown in the picture of the options. Please choose according to your needs.
1. The first type of option consists only of submarines with airstone.
2. The second type of option consists of submarines with airstone and accessories.
3. The third type of option consists of submarines with airstone, accessories and air pumps. (you will need to choose the right voltage version of the air pump based on the voltage l in your area)  

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. Silent Oxygen Pump(optional): You can choose a silent air pump with corresponding voltage and plug according to your region.

2. Creative Decoration Bubble Stone: Various styles of decorative bubble stones are available for you to choose from, adding oxygen to the water while perfectly decorating your fish tank, creating a unique scenery.
3. Air tube(optional): Standard size trachea with an inner diameter of 4mm.
4. Check Valve(optional): 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(optional): The number of bubbles can be adjusted by adjusting the control valve.
6. Square Bent(optional): 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(optional): The suction cup is used to fix the air tube, keep the fish tank clean, and can also be used to fix electrical wires.
8. Three-way connector(free): Split the air pipe in two and connect the two decorative bubble stones using an air pump. Three-way connectors will be complimentary with purchase of two sets.

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




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.

Decorative Bubble Stone:

1. Three submarines in different colors can be fitted with complimentary bubble stone(Please refer to video),can both produce bubbles for oxygen and decorate your fish tank!
2. Bubble stone using super hard gold steel sand, after high temperature sintering, good gas diffusion, good filterability, ozone resistance, corrosion.
3. Increase oxygen levels, lower CO2 and raise PH, creates water currents.
4. 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.
5. Two or more bubble stones can be connected to the same air pump through Three-way connector.

Air Tube

1. Standard size air tube with an inner diameter of 4mm.
2. Good flexibility, resistance to distortion, not easy to deform.

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 for fish tank equipment.

 

Check Valve

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

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).

 

 

Control Valve

1. The number and size of bubbles can be adjusted by adjusting the volume of gas with the control valve. 
2. When the air pump does not have the function of regulating the air volume, the control valve can achieve this function.

 

Square Bent

1. When the air tube is bent at 90 degrees, it hinders air transmission, and a square bent can effectively solve this problem.
2. Keep the fish tank tube clean and leave more room for the fish to move around.

Three Way connector

1.Split the air pipe in two and connect the two bubble stones using an air pump.
2. When using a three-way connector, control valves can be installed separately on the two forked tubes to regulate the amount of air flowing on the two tubes.
