The Top Aqua Super Diffuser is designed for hobbyists who demand high-efficiency CO2 delivery. The precision ceramic membrane produces a massive number of micro-bubbles, increasing the surface area contact with water. For the best results, place the diffuser near the substrate and directly beneath your filter's outflow; this allows the bubbles to be swept across the tank, extending their contact time with the water.Performance: High-performance ceramic membrane for ultra-fine bubbles.Installation: Includes a strong suction cup for firm, adjustable placement.Compatibility: Recommended for use with pressurized CO2 cylinder systems.Materials: Durable, high-quality construction for long-term use.
