Frequently Asked Questions

What airline tubing size does this use?

Standard 3/16in airline tubing — compatible with all Danner® and most other brand air pumps.

How does an air stone improve plant health?

Fine bubble aeration increases dissolved oxygen in the nutrient solution, which accelerates nutrient uptake, supports beneficial microorganisms, and prevents the anaerobic conditions that lead to root rot.

Do I need any special fittings?

No — simply push the 3/16in airline tubing onto the barbed end of the air stone for a secure connection.

How long will this air stone last?

Mineral deposits from hard water can gradually clog air stones. Soak in a dilute white vinegar solution periodically to restore airflow and extend service life.
