This flexible aquarium air stone is an ideal solution for increasing dissolved oxygen in your fish tank, pond, or aquatic breeding setup. Made from high-quality rubber material, the self-sinking air strip features dense micro air outlets that produce a consistent stream of fine bubbles, enhancing both oxygenation and visual appeal. The oxygen diffuser tube is fully bendable and customizable, allowing you to shape it freely along the tank floor or into decorative water curtain effects. Available in lengths from 20cm to 120cm, this air stone supports both single-inlet and dual-inlet use, depending on the size. Designed for easy integration with standard 4mm air tubing and external air pumps, it is perfect for aquariums, hydroponic setups, or oxygenation in warmer water conditions.

For dual-inlet models, both ends require air input from a dual-output pump.
After extended use, soak in warm water for 8 minutes and gently scrub to restore bubble performance.
