Key Features:

• High-Definition Transparency: The diffuser's clear cylindrical body allows easy monitoring of CO2 flow, ensuring efficient operation at all times.
• Precision Ceramic Atomizing Core: Equipped with a large, replaceable ceramic core, this diffuser creates an ultra-fine mist of CO2 bubbles, with a diameter of less than 0.1mm, maximizing CO2 absorption in your aquarium.
• Safety and Durability: A built-in safety check valve prevents backflow, protecting your CO2 equipment from potential damage. The diffuser's solid design and firm locking nuts ensure that hoses remain securely connected during use.
• Convenient Installation: The quick push-and-pull installation system, featuring a built-in locking device, allows for effortless setup and maintenance. Simply press the check valve gasket down to release the CO2 tubing when needed.
• Optimal Performance: For best results, soak the ceramic core for 24-48 hours before use to enhance atomization. A minimum working pressure of 20 psi is required for efficient CO2 diffusion.

• Install the diffuser securely outside of the aquarium on the outflow pipe of your aquarium filter.
• Connect the CO2 hose from the diffuser's check valve to your CO2 regulator.
• Always check for leaks upon installation to ensure a secure fit.
• A subtle sound during operation indicates normal CO2 diffusion through the ceramic core.
