KSY Aquatics 30" Flexible Aquarium Air Stone Bubble Wall — 75cm Double-Head Micro-Porous Diffuser

One Tube. Any Shape. Endless Bubbles.

Rigid air stones sit in one spot and bubble in one direction. The KSY Aquatics flexible bubble wall tube bends into any shape you need. Curve it along the back wall for a full curtain of bubbles. Coil it around a centerpiece decoration. Loop it into a circle for a 360° aerated display. At 75cm (about 30 inch), it stretches the length of small to medium tanks without joints or connectors breaking the bubble line.

Micro-Porous = More Oxygen, Less Noise

The entire tube surface is micro-porous silicone — thousands of ultra-fine pores produce a dense, even stream of tiny bubbles. Compared to a standard ceramic air stone of the same length, the bubble wall generates significantly more oxygen exchange with quieter operation. No loud gurgling. No sudden bubble bursts that startle your fish.

Sinks on Its Own — No Suction Cups Needed

The tube is weighted to sink immediately and stay put. No suction cups to adjust. No floating corners. Place it anywhere on the substrate, bury it slightly under gravel, or tuck it behind hardscape — it stays where you put it.

Double-Head Design (75cm and above)

Models 75cm and longer feature air inlets on both ends. Connect one pump for standard use, or two pumps for extra-long tanks that need even bubble distribution from both sides.
