External CO2 Atomiser with Locking Bolt Seal – Ultra-Fine Ceramic Diffuser
The Castle Dawn Aquatics External CO2 Atomiser delivers a powerful and secure method of diffusing CO₂ into your aquarium. Designed for use with high-pressure CO₂ systems, this pro-grade atomiser uses a high-density ceramic tube to create ultra-fine bubbles, ensuring maximum dispersion throughout the water column.
Its robust locking bolt mechanism provides a tight, leak-proof seal, even under high pressure, making it a reliable choice for aquascaping setups. Available in two sizes (M1 for 16/22 mm tubing and M2 for 12/16 mm tubing), this external diffuser connects securely to your CO₂ line and remains outside the tank for a cleaner aesthetic. Includes a 1‑Year Warranty as a mark of our confidence in its build quality.
