What does a Coke Can Air Stone do?
It takes air supplied by an external air pump and disperses it as bubbles through water or nutrient solution. This increases aeration and encourages movement within the reservoir.

70mm Coke Can Air Stone – Hydroponic Aeration Diffuser

Unit price perEstimated delivery between September 16 and September 18.
High-output 70mm cylindrical air stone for increasing aeration and circulation in hydroponic nutrient reservoirs and DWC systems.
The 70mm Coke Can Air Stone is designed to disperse air throughout water or nutrient solution, helping growers maintain a well-aerated root environment. Its cylindrical shape provides a larger diffusing surface than smaller ball-style air stones, making it a useful choice for hydroponic reservoirs and systems requiring a stronger level of aeration.
Connect the air stone to a suitably powerful external air pump and submerge it in the reservoir. Air is forced through the porous body, creating a continuous spread of bubbles that helps increase dissolved oxygen and keeps the surrounding nutrient solution moving.
Coke can air stones are particularly well suited to DWC, bubbler systems and nutrient reservoirs. Several can also be run from a larger air pump using a suitable airline manifold for multi-pot or multi-reservoir installations.
Why choose a 70mm Coke Can Air Stone?
- High-output aeration – designed for use with a substantial airflow to provide vigorous nutrient solution aeration.
- Cylindrical diffuser – the porous body disperses incoming air as bubbles throughout the surrounding solution.
- Supports dissolved oxygen levels – helps maintain an oxygen-rich nutrient solution around hydroponic roots.
- Improves water movement – continuous bubbling helps circulate nutrient solution within the reservoir.
- Ideal for DWC – particularly useful in deep water culture, bubbler and other actively aerated hydroponic systems.
- Suitable for larger setups – multiple air stones can be supplied from a suitably sized air pump and manifold.
What is a Coke Can Air Stone used for?
A Coke Can Air Stone is a porous diffuser used to introduce air into water or hydroponic nutrient solution. Unlike an open airline that releases air from a single point, the porous surface breaks the incoming airflow into a continuous spread of bubbles.
In hydroponics, this makes it particularly useful for aerating nutrient reservoirs and systems where plant roots remain in or have regular contact with nutrient solution. The moving bubbles increase gas exchange and help prevent the water immediately around the diffuser from remaining stagnant.
Ideal for DWC and hydroponic reservoirs
The larger cylindrical design makes this air stone particularly useful in deep water culture systems and nutrient tanks where stronger aeration is required. It can be positioned towards the bottom of the reservoir so bubbles rise through the nutrient solution before reaching the surface.
For multi-pot systems, several air stones can be connected to a suitably sized air pump. An airline manifold can divide the main air supply into individual feeds for each reservoir or growing position.
How to use the 70mm Coke Can Air Stone
Connect the air stone to compatible airline running from a suitable external air pump or compressor. Submerge the complete porous section of the air stone in the water or nutrient solution, ideally positioning it towards the bottom of the reservoir.
Switch on the air pump and check that bubbles are being produced across the diffuser. This 70mm Coke Can Air Stone is designed for relatively high airflow and is listed for approximately 5 – 10 litres of air per minute, so the connected pump should be appropriately sized.
If bubble production reduces over time, inspect the airline and air stone for restrictions or mineral deposits. Keeping the diffuser clean helps maintain consistent airflow through its porous surface.

70mm Coke Can Air Stone FAQs
What size is the 70mm Coke Can Air Stone?
This version measures approximately 70mm high and 30mm in diameter.
How much airflow does the 70mm Coke Can Air Stone need?
This Coke Can Air Stone is designed for approximately 5 – 10 litres of airflow per minute, so it should be paired with a suitably sized air pump.
Is a Coke Can Air Stone suitable for DWC?
Yes. Its cylindrical diffusing surface makes it particularly useful for aerating nutrient solution in DWC buckets and other deep water culture systems.
Can I use this air stone in a nutrient reservoir?
Yes. It can be submerged in a hydroponic nutrient reservoir to provide continuous aeration and help keep the solution moving.
Where should I position a Coke Can Air Stone?
Position it below the surface of the solution, preferably towards the bottom of the reservoir. This gives the bubbles more opportunity to travel through the water before reaching the surface.
Can I run several Coke Can Air Stones from one pump?
Yes, provided the air pump has sufficient output. A suitable manifold can be used to divide the main air supply between several individual air stones.
Why has my air stone started producing fewer bubbles?
Reduced bubbling can be caused by restricted airline, insufficient pump output or deposits building up within the porous diffuser. Inspecting the airline and cleaning the air stone can help restore airflow.
Does the Coke Can Air Stone include an air pump?
No. The air stone is supplied separately and requires a compatible airline and suitably sized external air pump or compressor.
