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.

150mm Ceramic Air Stone FAQs
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.
