Pawfly Aquarium Air Stone Bar Bubbler, 12-Inch 4-Pack for Medium Bubble Diffusion

Pawfly Aquarium Air Stone Bar Bubblers create a rectangular wall of medium bubbles to help increase oxygen solubility in aquariums, ponds and DWC systems; this four-pack includes 12-inch (30.48 cm) bars with four suction cups each.

• Four 12-inch air stone bars — arrange bubbling across medium or large tanks, ponds or DWC reservoirs.
• Medium bubbles form a rectangular cascade — help increase oxygen solubility in the water.
• 3.3 L/min jetting volume and a recommended 7 W air pump — support steady air diffusion.
• Mineral material in a green plastic base — made for use with fish and aquatic roots.
• Four suction cups per bar — secure the bubbler to a tank surface.

These Pawfly bubblers are made for aquatic setups that need a spread of bubbles rather than a single concentrated outlet. The long bar creates a rectangular bubble wall, making it suited to medium or large fish tanks, ponds and deep water culture (DWC) systems. Each bar weighs 3 oz (85 g), and the four-piece pack lets you place multiple bubblers within a setup.

What does the Pawfly air stone bar do?

It diffuses air into medium bubbles that rise in an abundant cascade, forming a rectangular wall and helping increase oxygen solubility in the water. The bubbler is intended for aquariums, ponds and DWC reservoirs, including setups where aquatic roots are growing.

• Bar size: 12 in (30.48 cm) long, 0.8 in (2.03 cm) wide and 0.5 in (1.27 cm) thick.
• Jetting volume: 3.3 L/min; recommended air pump power: 7 W.

What air pump tubing does it fit?

Pawfly air stone bars use standard airline tubing with a 3/16-inch (4.76 mm) inside diameter. Connect the tubing to an air pump to supply air for diffusion through the stone.

• Each bar comes with four suction cups for positioning in the tank.
• Choose a pump with the recommended 7 W power for these bubblers.

How do you prepare and maintain the bubbler?

Soak the Pawfly air stone completely in water for one hour before use. Brush it regularly to clear buildup; the stone can become clogged after weeks or months of use.

• Fully submerge the stone for the full one-hour pre-use soak.
• Use a brush for cleaning when regular use leads to clogging.

The four-bar set suits aquarium, pond and DWC keepers who want medium bubbles distributed in a rectangular wall and have a compatible air pump and tubing. Each bar combines mineral air-stone material with a green plastic base and four suction cups, with dimensions suited to medium or large aquatic setups.
