Danner® Supreme Hydroponics™ Air Stone - 6in

Fine-Bubble Reservoir Aeration for Root Zone Oxygen, 6in

Low dissolved oxygen in a nutrient reservoir slows root uptake and invites the anaerobic conditions behind root rot. The Danner® Supreme Hydroponics™ 6in Air Stone addresses that directly, releasing a curtain of fine bubbles that add oxygen and help drive off excess CO2.

Its 6in length spreads bubbles evenly across a reservoir rather than concentrating them in one spot, and it connects to any standard 3/16in airline tubing running from your air pump with no special fittings required.

Key Features & Benefits

• 6in length — broad, even bubble distribution across the reservoir.
• Adds oxygen, removes CO2 — improves dissolved oxygen levels that support root health and beneficial microbial activity.
• Standard 3/16in tubing compatibility — connects directly to any standard air pump outlet.
• Durable construction — built for continuous submerged use in nutrient solution and pond water.

Who Should Use This

Hydroponic growers and pond keepers who want to raise dissolved oxygen levels, support root zone health, and reduce CO2 buildup in a reservoir are the direct fit for this air stone.

About Danner

Danner Manufacturing's Supreme Hydroponics™ line traces back to the company's 1934 founding in a Brooklyn cellar and its 1974 relocation to Islandia, New York, where it remains family-owned today.

Frequently Asked Questions

What airline tubing size does this air stone use?

Standard 3/16in airline tubing — compatible with Danner® pumps and most other brand air pumps. No adapter is needed for a standard connection.

How does an air stone improve plant health?

Fine-bubble aeration raises dissolved oxygen in the nutrient solution, which speeds nutrient uptake and supports beneficial microorganisms. It also helps prevent the anaerobic conditions that lead to root rot in a standing reservoir.

Do I need any special fittings to connect it?

No — simply push standard 3/16in airline tubing onto the barbed end of the air stone. That gives a secure, leak-free connection without additional parts.

How long will this air stone last before it needs replacing?

Mineral deposits from hard water can gradually clog the pores and reduce bubble output over time. Soaking the stone in a dilute white vinegar solution periodically restores airflow and extends its service life.
