UNS CO2 Diffuser

Fine CO2 mist for lush, thriving plants

Watch a cloud of tiny CO2 bubbles drift through your planted tank and feed every stem and leaf. The UNS (Ultum Nature Systems) CO2 Diffuser breaks pressurized CO2 into a fine mist, so more of it dissolves into the water and less escapes at the surface.

Why aquascapers love it

• Efficient dissolution: A fine diffusion membrane creates tiny bubbles that dissolve quickly.
• Clean, minimal look: Clear design blends into nature-style aquascapes.
• Healthier plant growth: Steady CO2 supports vibrant color and dense, compact growth.
• Easy setup: Connects to standard CO2 tubing from your pressurized system.

Good to know

Requires a pressurized CO2 system. Place low in the tank near water flow for best distribution, and use a check valve to protect your regulator.
