High quality airstones designed to increase dissolved oxygen levels and keep your nutrient solution fresh, oxygen rich and ready for fast root development. Each stone produces a fine stream of bubbles that break the surface tension of the water, improving gas exchange and supporting stronger, healthier growth.

Oxygen rich water is essential for any hydroponic system. Higher DO levels help maintain a clean root zone, support faster nutrient uptake and reduce the risk of anaerobic conditions in reservoirs. These airstones are compatible with all standard air pumps and can be used in DWC, recirculating systems, reservoirs, mixing tanks and propagation setups.

Why Use Airstones

• Improves dissolved oxygen levels for stronger, more resilient root systems.
• Helps maintain a fresher, more stable nutrient solution.
• Supports faster nutrient uptake and plant growth.
• Reduces stagnant water pockets and helps prevent odours.
• Pairs with any air pump and standard silicone airline tubing.

Choosing the Right Shape

• Round Stones (4, 6, 8 inch): Ideal for large reservoirs where wide, even bubble distribution is needed.
• Golf Ball Stones: Compact and excellent for small buckets, small tanks or propagation systems.
• Cylinder Stones: Perfect for mounting vertically or in narrow spaces where directional aeration is preferred.

How to Use

• Attach to any air pump using standard 4 mm airline tubing or 8mm airline tubing
• Submerge fully for best performance.
• Rinse before first use to remove manufacturing dust.
• For maximum oxygenation, match one airstone to every 10 to 25 litres of reservoir volume depending on pump size.

Maintenance Tips

• If airflow slows, soak the stone in warm water to remove mineral buildup.
• Replace stones periodically to maintain strong, consistent aeration.
• Pair with a larger pump to increase bubble density and DO levels.

Whether you run deep water culture, simple bucket systems or large recirculating setups, these airstones help keep your nutrient solution at peak oxygen levels for healthy, vigorous plant growth.
