• Medium Bubbles: The air stone always produces an abundant cascade of dense bubbles，enlivening the aquatic life. Keeping your fish or plant roots growing healthily
• Steady Output: Recommended pump power: > 3 W; Standard ID airline tubing: 7/16". Efficient bubbler for constant air diffusion. Ideal for oxygenation in aquariums, fish tanks, buckets, or small ponds
• Stable in Water: The air stone bubble diffuser can sink to the bottom quickly. Featuring 4 anti-sliding pads on the bottom, it always lies steadily in the water without moving easily when bubbling
• Easy to Use: First, fully immerse the air stone in water for 5-10 minutes, Then use a tubing to connect the stone and air pump. Finally, turn on the pump (for about 3 seconds) to test the airstone. If the bubbles are uneven, perform exhaust correction.
