What is an 8 way airline manifold used for?
An airline manifold takes the output from one air pump or compressor and divides it into several smaller airline feeds. This allows multiple air stones, air curtains or aeration points to operate from the same main air supply.
The eight 4mm outlets make it particularly useful for larger hydroponic or irrigation setups where several reservoirs, tanks or growing positions require aeration at the same time.
How to use the 8 Way Plastic Airline Manifold
Connect the 8mm inlet to a suitable airline running from your air pump or compressor. Attach individual 4mm airline lengths to the eight outlet connections, then route each line to the required air stone, air curtain or aeration point.
Position the manifold where the airline runs can be kept tidy and as direct as possible. Keeping individual outlet lines reasonably similar in length can also help create a more balanced aeration layout.
The amount of air reaching each outlet will depend on the performance of the air pump, the number of outlets being used, airline length and the resistance created by the connected air stones or diffusers.

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.

Large 100mm cylindrical air stone for powerful aeration and circulation in hydroponic nutrient reservoirs and DWC systems.
The 100mm Coke Can Air Stone is a large porous air diffuser designed to introduce a continuous supply of bubbles into water or hydroponic nutrient solution. Its substantial cylindrical surface provides plenty of area for dispersing air, making it particularly useful in larger reservoirs and systems that need vigorous aeration.
Connect the air stone to a suitably powerful external air pump and position it below the surface of the nutrient solution. Air passes through the porous diffuser and emerges as bubbles, increasing aeration while helping to keep the surrounding solution moving.
The 100mm version measures approximately 100mm high by 50mm in diameter, giving it a larger diffusing body than the 70mm Coke Can Air Stone. It is a useful choice for DWC systems, bubbler systems and larger hydroponic nutrient reservoirs.
Why choose a 100mm Coke Can Air Stone?
- Large cylindrical diffuser – provides a substantial porous surface for distributing air through nutrient solution.
- Strong reservoir aeration – ideal for systems where a higher level of aeration is required.
- Supports dissolved oxygen levels – helps maintain an oxygen-rich nutrient solution around hydroponic roots.
- Encourages water movement – rising bubbles help circulate the surrounding nutrient solution.
- Ideal for DWC – well suited to deep water culture, bubbler systems and larger nutrient reservoirs.
- Suitable for multi-pot installations – several air stones can be supplied from a suitably sized air pump using an airline manifold.
What is a 100mm Coke Can Air Stone used for?
A Coke Can Air Stone is submerged in water or nutrient solution and supplied with air from an external pump. The porous body breaks the incoming airflow into bubbles rather than releasing air from a single open airline.
This makes the 100mm version particularly useful for hydroponic nutrient tanks and DWC systems where continuous aeration is needed around submerged roots. Its larger cylindrical body also makes it a practical option for bigger reservoirs where a small air stone may not provide the desired spread of bubbles.
Ideal for larger hydroponic reservoirs
At approximately 100mm high and 50mm in diameter, this is a sizeable air diffuser designed for use with a suitable high-output air pump. Positioning the air stone towards the bottom of a reservoir allows bubbles to rise through more of the nutrient solution before reaching the surface.
Several Coke Can Air Stones can also be incorporated into a larger aeration system. A suitable airline manifold allows one sufficiently powerful air pump or compressor to supply individual air stones across several reservoirs or growing positions.
How to use the 100mm Coke Can Air Stone
Connect the air stone to compatible airline running from a suitable external air pump or compressor. Place the air stone in the nutrient tank or reservoir, keeping the porous diffuser submerged and preferably positioned towards the bottom.
Switch on the air pump and check that bubbles are being produced through the diffuser. Coke Can Air Stones require a substantial air supply, with current UK hydroponic listings specifying approximately 5 – 10 litres of air per minute, so use a pump capable of providing the required airflow.
If the air stone is being used as part of a multi-outlet system, remember that the pump's total output is shared between all connected diffusers. The air pump therefore needs to be sized for the complete aeration setup rather than for a single air stone.
Over time, deposits can restrict the porous surface and reduce bubble production. Keeping the diffuser clean and checking the airline for kinks or blockages will help maintain consistent performance.

50m roll of porous 4mm bubbler tubing for creating custom-length air diffusers and an even wall of bubbles in hydroponic reservoirs.
This 4mm Bubbler Tubing gives growers a flexible alternative to conventional air stones. Instead of carrying air to a separate diffuser, the porous tubing releases air through its surface, producing bubbles along the length of the tube.
Supplied as a 50m roll, it can be cut and arranged to suit different reservoir shapes and aeration layouts. This makes it particularly useful for custom hydroponic systems, larger nutrient tanks and applications where you want to spread aeration across a wider area rather than concentrate it around a single air stone.
The tubing has a 4mm internal diameter and approximately 9mm external diameter. Connect it to a suitable air supply, close the far end and position the porous section within the reservoir to create your own air diffuser.
Why choose 4mm Bubbler Tubing?
- Creates a wall of bubbles – porous tubing disperses air along its length rather than from one single outlet.
- Custom aeration layouts – cut the tubing to suit individual reservoirs and growing systems.
- 50m roll – provides plenty of tubing for larger installations or multiple aeration sections.
- 4mm internal diameter – suitable for integration with compatible aeration fittings and air supplies.
- Flexible positioning – arrange the tubing to spread bubbles across the area where aeration is needed.
- Ideal for hydroponics – useful in nutrient reservoirs, DWC systems and custom hydroponic installations.
What is bubbler tubing used for?
Bubbler tubing is a porous air diffuser supplied in flexible tube form. When connected to an air pump, air passes through the walls of the submerged tubing and creates a fine, even spread of bubbles.
Because the tubing itself acts as the diffuser, growers can create aeration layouts that follow the shape of a reservoir or cover a wider area than a small individual air stone. It is particularly useful for DIY hydroponic systems and custom reservoir setups.
Bubbler tubing or an air stone?
A conventional air stone concentrates aeration around a fixed diffuser. Bubbler tubing allows the diffusing area to be extended along a chosen length, giving you more freedom over where bubbles are produced within the reservoir.
This makes bubbler tubing a useful option for long tanks, larger reservoirs and unusual layouts where several fixed air stones would otherwise be needed to spread aeration across the available space.
How to use 4mm Bubbler Tubing
Cut the bubbler tubing to the required length for your reservoir or aeration layout. Connect one end to a compatible airline supply from a suitably sized air pump, using the appropriate connector where required.
Seal the opposite end with a compatible stop end so that the incoming air is forced through the porous wall of the tubing. Position the bubbler tubing below the surface of the water or nutrient solution, then switch on the air pump and check that bubbles are being produced along the required section.
Longer lengths of bubbler tubing place greater demand on the air supply, so the connected pump should be sized for the amount of tubing being operated and the level of aeration required.

4mm Bubbler Tubing FAQs
What is bubbler tubing?
Bubbler tubing is porous tubing designed to act as an air diffuser. When connected to an air pump and submerged, air escapes through the tubing wall to create bubbles along its length.
Does bubbler tubing replace an air stone?
Yes, it can. The porous tubing itself acts as the diffuser, so a separate air stone is not required at the end of the bubbler section.
What size is this bubbler tubing?
The tubing has a 4mm internal diameter and approximately 9mm external diameter. This product is supplied as a 50m roll.
Can I cut bubbler tubing to length?
Yes. One of the main advantages of bubbler tubing is that it can be cut to create an aeration section suited to the reservoir or hydroponic system being built.
Do I need to seal the end of bubbler tubing?
Yes. The far end should be closed with a compatible stop end so that the supplied air is forced through the porous tubing rather than escaping freely from the open end.
Can I use bubbler tubing in a hydroponic reservoir?
Yes. It is particularly useful for hydroponic reservoirs because the tubing can be positioned to distribute bubbles across a wider area of nutrient solution.
Is bubbler tubing suitable for DWC?
Yes. Bubbler tubing can be used as a diffuser in DWC systems where continuous nutrient solution aeration is required.
What air pump do I need for bubbler tubing?
The required pump capacity depends on the length of bubbler tubing being operated and the aeration required. Longer diffuser runs need a greater air supply than short sections, so the pump should be sized for the complete setup.
Can I make a custom-shaped air diffuser with bubbler tubing?
Yes. Its flexible format makes bubbler tubing useful for creating custom aeration layouts within reservoirs where a conventional fixed air stone may not provide the desired coverage.
200m roll of clear 4mm airline tubing for connecting air pumps and manifolds to air stones, diffusers and hydroponic aeration equipment.
This 4mm Clear Airline Tubing provides the link between your air pump and the equipment doing the aerating. Supplied on a generous 200m roll, it is ideal for building larger hydroponic aeration systems, replacing old airline or cutting multiple individual runs for pots and reservoirs.
Use it to carry air from a compatible air pump directly to an air stone, or connect it to the outlets of an airline manifold when one larger pump is supplying several aeration points.
The long 200m roll is particularly useful for commercial grow rooms, propagation areas and multi-pot hydroponic installations where numerous lengths of airline are needed from one central supply.
Why choose 4mm Clear Airline Tubing?
- 200m roll – plenty of airline for large installations, replacement runs and multiple growing systems.
- 4mm airline – a widely used size for hydroponic air stones, manifolds and aeration accessories.
- Clear tubing – a clean, unobtrusive choice for grow rooms, reservoirs and propagation systems.
- Cut to the length you need – create individual airline runs to suit the layout of each system.
- Connect pumps to air stones – carries air between compatible pumps, manifolds, air stones and diffusers.
- Ideal for larger aeration systems – particularly useful where numerous pots or reservoirs require individual airline feeds.
What is 4mm airline tubing used for?
Airline tubing carries air from an external air pump to an air stone, diffuser or other aeration accessory. In hydroponic systems, this allows growers to position the pump away from the reservoir while delivering air directly to the submerged diffuser.
It can also be used with compatible airline manifolds. A larger incoming air supply is divided at the manifold, with individual lengths of 4mm airline then running to separate air stones or aeration points.
This makes a 200m roll particularly practical for DWC systems, nutrient reservoirs, propagation setups and larger multi-pot installations where many separate airline runs are required.
How to use 4mm Airline Tubing
Cut the airline to the length required for your installation. Push one end securely onto the compatible outlet of your air pump or manifold and connect the other end to an air stone, diffuser or other suitable aeration accessory.
Route the tubing neatly between the air supply and reservoir, avoiding sharp bends, crushing or kinks that could restrict airflow. For multi-pot installations, cut individual runs from the roll and connect them to the corresponding outlets on the manifold.
When planning a larger system, remember that longer airline runs and multiple air stones increase the demand placed on the pump. The air pump should therefore provide enough total airflow for the complete installation.

150mm flat ceramic air stone for producing a wide spread of fine bubbles across hydroponic nutrient reservoirs and DWC systems.
The 150mm Round Flat Ceramic Air Stone provides a simple way to increase aeration and movement throughout a hydroponic nutrient solution. Its broad, porous ceramic surface releases air as many small bubbles, spreading aeration over a much wider area than a compact ball-style air stone.
At 150mm or 6 inches in diameter, the disc sits flat at the bottom of a reservoir or tank. Connect the 4mm inlet to a suitable air pump using compatible airline and the incoming air is distributed through the porous ceramic body.
It is particularly useful for DWC systems, hydroponic nutrient reservoirs and other growing systems where continuous aeration helps keep the solution moving around the root zone.
Why choose a 150mm Flat Ceramic Air Stone?
- Wide 150mm diffuser – spreads aeration across a larger area of the reservoir.
- Porous ceramic construction – produces many small bubbles through the surface of the air stone.
- Flat circular design – sits neatly at the bottom of tanks and nutrient reservoirs.
- 4mm inlet – connects to compatible 4mm airline and a suitable external air pump.
- Improves nutrient solution movement – rising bubbles help circulate the surrounding solution.
- Ideal for hydroponics – suitable for DWC, nutrient reservoirs and other actively aerated growing systems.
What is a flat ceramic air stone used for?
A flat ceramic air stone is a submerged diffuser that takes air from an external pump and distributes it through thousands of small pores. Instead of releasing air from a single open airline, the ceramic surface produces a broad spread of bubbles across the reservoir.
The 150mm disc format is particularly useful where you want aeration distributed across a wider area. Its low, flat shape allows the air stone to sit at the bottom of the tank while bubbles rise through the nutrient solution above it.
Ideal for DWC and nutrient reservoirs
In deep water culture systems, roots spend extended periods in nutrient solution, making active aeration an important part of the setup. A flat air stone positioned beneath the root zone creates a continuous stream of bubbles while helping keep the nutrient solution moving.
The 150mm size is also well suited to standalone nutrient reservoirs and other hydroponic tanks where a broader diffusing surface is preferred to a small individual air stone.
How to use the 150mm Ceramic Air Stone
Connect compatible 4mm airline to the inlet on the side of the air stone, then connect the other end to a suitably sized external air pump. Place the ceramic disc flat at the bottom of the reservoir and keep the porous section submerged.
Once the pump is switched on, air passes through the ceramic body and bubbles rise through the surrounding water or nutrient solution.
Keep the airline free from kinks and restrictions. For added protection against water travelling back towards the pump when it is switched off, the air pump can be positioned above the water level or a suitable non-return valve can be incorporated into the airline.

What size airline does the 150mm air stone use?
This 150mm version has a 4mm inlet for connecting compatible airline to a suitable air pump.
What does a ceramic air stone do?
Air supplied by an external pump passes through the porous ceramic body and is released as many small bubbles, helping aerate and circulate the surrounding water or nutrient solution.
Is the 150mm air stone suitable for DWC?
Yes. Its broad diffusing surface makes it particularly useful for aerating nutrient solution in deep water culture systems.
Where should I position a flat air stone?
Place it flat towards the bottom of the reservoir or tank. This allows bubbles to rise through the nutrient solution from a low position in the system.
Does this air stone need an air pump?
Yes. The ceramic air stone is a diffuser and requires a suitable external air pump to supply the airflow.
Is an air pump or airline included?
No. The air stone is supplied separately, so a suitable air pump and compatible 4mm airline are required to create a complete aeration setup.
Can I use more than one 150mm air stone?
Yes. Multiple air stones can be incorporated into a larger aeration system provided the connected air pump has sufficient output. A suitable manifold can be used to divide the air supply between separate airline runs.
Why use a flat air stone instead of a small ball air stone?
The larger flat ceramic surface spreads bubbles across a wider area, making it useful when you want broader aeration across the bottom of a nutrient reservoir rather than a concentrated stream from a smaller diffuser.
100mm flat ceramic air stone for creating a wide spread of fine bubbles in hydroponic nutrient reservoirs and DWC systems.
The 100mm Round Flat Ceramic Air Stone provides effective aeration without taking up unnecessary space in the bottom of a reservoir. Its broad porous surface disperses air as many small bubbles, helping oxygenate the nutrient solution while creating useful movement within the tank.
Measuring 100mm, or approximately 4 inches, across, this compact ceramic disc sits flat on the bottom of a reservoir. Connect it to a suitable external air pump using compatible airline and air is forced through the porous stone before bubbling through the surrounding solution.
It is a practical choice for DWC buckets, hydroponic nutrient reservoirs and other systems where continuous aeration is required around the root zone.
Why choose a 100mm Flat Ceramic Air Stone?
- Wide bubble distribution – the 100mm circular surface spreads aeration across a broader area than a small ball-style air stone.
- Porous ceramic diffuser – releases incoming air as many small bubbles through the surface of the stone.
- Flat profile – sits neatly at the bottom of buckets, tanks and nutrient reservoirs.
- Compact 100mm size – well suited to individual DWC buckets and smaller hydroponic reservoirs.
- Improves nutrient solution movement – rising bubbles help keep the surrounding solution circulating.
- Ideal for hydroponics – suitable for DWC, nutrient reservoirs and other actively aerated growing systems.
What is a flat ceramic air stone used for?
A flat ceramic air stone acts as a submerged diffuser. Air supplied by an external pump is forced through the many pores in the ceramic body, creating a spread of small bubbles rather than releasing the air from one open airline.
As those bubbles rise through the reservoir they create movement in the nutrient solution and increase aeration. The flat disc design also keeps the diffuser low in the tank, allowing bubbles to rise through the water from near the bottom of the reservoir.
Ideal for DWC and hydroponic reservoirs
The 100mm size is particularly useful for DWC buckets and individual nutrient reservoirs where a compact diffuser with a broad bubbling surface is required.
For larger hydroponic installations, several ceramic air stones can be positioned in separate pots or reservoirs. A suitably sized air pump and manifold can then distribute air between the individual diffuser lines.
How to use the 100mm Ceramic Air Stone
Connect suitable flexible airline between the ceramic air stone and an appropriately sized external air pump. Place the air stone flat at the bottom of the reservoir, keeping the porous ceramic section submerged.
Switch on the pump and air will pass through the porous surface, producing bubbles throughout the surrounding nutrient solution. Positioning the diffuser low in the reservoir gives those bubbles more distance to travel before reaching the surface.
Keep airline runs free from kinks and restrictions that could reduce airflow. Positioning the air pump above the water level helps protect it against water siphoning back through the airline if the power is switched off.
