• This 10 inch aquarium air stone creates a steady flow of bubbles. This also increases the oxygenation of your fish tank. Attaches easily to any air pump with a standard 3/16” airline tubing. Multiple stones can be attached in a series for larger tanks. This aquarium aerator has extended sides to be covered in gravel which holds product to bottom of aquarium. Even with the strong flow of bubbles it will stay secure. Air stone can be positioned anywhere in your fish tank. Blue color blends in with surroundings or it can be hidden under gravel. Air Stone measures 10 inches in length by 2 inches wide and can be used in both  freshwater and saltwater tanks. TROUBLESHOOTING TIPS: Due to the larger size of this air stone, you may need to increase the flow on your air-pump. We also recommend using a pump that puts out at least 1.6-2.0 liters per minute to have enough air-flow to create a full wall of bubbles. If the end cap is not secure, air will leak out preventing bubbles from coming out through the stone. If your Air Stone gets clogged, you can rinse it with clean water to reopen the passages.
