Flat Circular Air Stone 8" (200mm)

High Output Reservoir Aeration

8" (200mm) Flat Circular Air Stone is designed to deliver powerful aeration in larger reservoirs, helping keep your nutrient solution oxygen-rich and constantly moving.

Its wide, flat design sits neatly at the bottom of your tank, producing fine, consistent bubbles that improve oxygen levels and support stronger, healthier root systems.

Key Benefits

• High oxygen output; improves dissolved oxygen in your solution
• Supports healthier roots; promotes faster growth and nutrient uptake
• Even bubble distribution; covers a wide reservoir area
• Reduces stagnant zones; keeps nutrients well mixed
• Durable design; protected casing with rubber feet for stability
• Ideal for large systems; built for high-output setups

Why You Need to Oxygenate Your Reservoir

In hydroponics, oxygen is just as important as nutrients. Without enough dissolved oxygen, roots can struggle, and harmful anaerobic conditions can develop.

This 8" air stone keeps your solution moving and oxygenated, helping maintain a healthy root zone and improving overall plant performance.

How to Set Up

• Place the air stone flat at the bottom of your reservoir
• Connect to an air pump using 8mm airline tubing
• Use a high-output air pump to maximise performance
• Submerge fully and run continuously

Important Notes

• Requires non-standard 8mm airline
• Needs a high-output air pump due to size
• Best suited for larger reservoirs and systems
