Week Aqua Inline CO₂ Atomizer (CO2-U-C-V)
$14.99 USD
Description

The Week Aqua CO₂ Atomizer (CO2-U-C-V) is an efficient in-tank CO₂ diffuser designed to produce ultra-fine carbon dioxide micro-bubbles for planted aquariums. Installed directly inside the tank, this atomizer maximizes CO₂ dissolution by increasing contact time with water, helping plants absorb carbon more effectively. Its precision diffuser core and durable housing deliver consistent performance, while its compact design stays discreet inside the aquarium. Ideal for aquascaping and high-growth planted systems, this atomizer enhances plant health, coloration, and overall vitality.

Key Features
  • Produces ultra-fine micro-bubbles for superior CO₂ absorption
  • Designed for in-tank placement
  • Compatible with standard CO₂ tubing and check valves
  • Durable construction for long-term aquarium use
  • Improves plant growth and color intensity
  • Helps maintain stable and efficient CO₂ levels

Ideal For

  • Planted aquariums (CO₂-enriched systems)
  • Aquascaped tanks with high light or nutrient demands
  • Carbohydrate-heavy plant species (carpeting, stems, etc.)
  • Aquarists seeking efficient in-water CO₂ diffusion
Why choose this series?

The Week Aqua CO₂ Atomizer (CO2-U-C-V) is engineered to outperform basic bubble diffusers by creating a much finer mist of CO₂ droplets that dissolve rapidly in the water. This improves plant uptake and reduces wasted gas escaping to the surface — a common issue with coarse bubble diffusers. With its compact, unobtrusive design, it easily blends into planted layouts without disrupting aesthetics. Whether you’re cultivating high-tech planted aquariums or maintaining balanced carbon levels in display tanks, this atomizer delivers reliable and enhanced CO₂ diffusion performance.
