Enhanced CO2 Absorption
The HC015 spiral diffuser is specially designed for planted aquariums. A unique spiral structure extends the path of CO2 bubbles, greatly increasing the dissolution rate. It is maximizing CO2 dissolution for healthier aquarium plants. Additionally, the air inlet features a conical structure, making it convenient to connect the air pipe.

Premium Ceramic Diffuser
Fine atomic pores produce slow-rising micro-bubbles for efficient CO2 distribution
