- 70% High-Efficiency CO2 Diffusion：The inline CO2 Diffuser effectively dissolves CO2 into the water flow, creating fine mist bubbles that maximize dissolution and enhance plant absorption. With up to 70% efficiency, it delivers cost savings and is perfectly suited for long-term use in planted aquariums.
- Space-Saving External Design：The external CO2 diffuser is mounted on the filter’s outflow pipe, eliminating the visual clutter caused by traditional in-tank diffusers. This setup reduces equipment inside the tank, providing more open space for a cleaner, more elegant appearance while simplifying maintenance.
- Even CO2 Distribution：The CO2 diffuser aquarium distributes CO2 through the filter’s outflow, effectively covering the entire aquarium to ensure even CO2 distribution and reduce dead spots, further enhancing plant absorption. It is particularly suited for medium to large aquariums, achieving efficient diffusion even in powerful filter flows, where intank co2 diffusers fall short in coverage.
- Durable Aluminum Construction：The aqurium CO2 diffuser features a sturdy aluminum alloy body for durability and corrosion resistance. It requires at least 30 psi working pressure and the replaceable ceramic diffuser that produces ultra-fine bubbles smaller than 0.1mm for optimal diffusion efficiency
- Versatile Size Compatibility – Available in three sizes to suit most standard aquarium setups: S (⌀13mm) for 1/2" ID tubing, M (⌀17mm) for 5/8" ID tubing, and L (⌀20mm) for 3/4" ID tubing. Each unit features secure hose-locking nuts to prevent leaks, along with a quick-connect push-fit system that allows for easy, tool-free installation and remova
