Marina 1 in. Cylinder Air Stone (2 Pack)

The Marina 1 in. Cylinder Air Stone (2 Pack) turns the output of any aquarium air pump into a steady stream of fine bubbles that oxygenate and gently circulate your water. Each pack includes two 1-inch cylindrical stones, and they are safe for both freshwater and saltwater aquariums. Just add an air pump and airline tubing (sold separately) and you are ready to go.

Features

• Boosts surface agitation and water circulation
• Works with any standard air pump and airline tubing
• Safe for freshwater and saltwater aquariums

How to Use

Connect the air stone to your air pump with standard airline tubing, then place it in the tank where you want bubbles and flow. A check valve is recommended between the pump and the stone to prevent back-siphoning. Rinse or replace the stone if the pores clog and airflow drops.

FAQ

Do I need an air pump? Yes. The air stone diffuses air supplied by an air pump; the pump and tubing are sold separately.

Is it for freshwater or saltwater? Both. These stones are safe for freshwater and saltwater aquariums.

How long do air stones last? Over time the pores can clog and airflow drops. Rinse the stone or swap in the second stone from the pack to restore a fine bubble stream.
