Efficient CO2 diffusion: Small air holes provide CO2 dissolution and even dispersion, supporting healthier aquatic systems by improving dissolved oxygen performance in a straightforward, sciencealigned way. Longlasting material: Made from rustproof aluminum alloy to deliver fine bubbles efficiently while maintaining a sturdy structure that resists clogging over extended use. Easy setup: Includes sturdy suction cups for secure placement, simple installation, and a spaceefficient Ushape design that supports straightforward operation and reliable performance. Seamless decor fusion: Built with refined workmanship and a smooth exterior to blend naturally with the tank's overall decorative scheme. Use scenarios Planted freshwater aquariums: Ideal for small to medium tanks that require stable CO2 diffusion to support plant growth and maintain healthy oxygen levels. Spaceconstrained setups: The spaceefficient Ushape and secure suction cups allow placement on glass walls without cluttering the substrate area or tank foreground. Longterm, lowmaintenance installations: Rustproof aluminum alloy and a design that resists clogging minimize maintenance while preserving performance over time. Specifications and features Material: rustproof aluminum alloy Diffusion: fine bubbles for effective CO2 dissolution and even dispersion Mounting: suction cups for secure, convenient placement Design: spaceefficient Ushape for compact, unobtrusive operation Function: engineered to improve dissolved oxygen performance through efficient CO2 diffusion
