Aquatees Stainless Steel Aquarium Co2 Diffuser

Elevate your planted aquarium with our professional-grade Stainless Steel C02 Diffuser collection. Engineered for durability and high-efficiency gas exchange, these diffusers replace fragile glass alternatives with a sleek, nearly indestructible design.

Available in three distinct series, each shape is precision-crafted to optimize pressure distribution and bubble misting based on your specific tank requirements.

DY-B Series: The Powerhouse (Large & Flat)

Designed for high-demand setups, the B Series features a massive 31mm flat disc. This wide horizontal surface area allows for maximum CO2 saturation, making it the ideal choice for large aquariums (150L+) and high-flow environments.

• Disc Diameter: 31mm
• Best For: Large tanks requiring high-volume gas exchange.

DY-C Series: High-Pressure Specialist (Small & Domed)

The C Series is built for stability and efficiency. Its 20mm high-dome shape is engineered to handle higher internal pressures, concentrating gas flow to ensure a consistent, ultra-fine mist. Perfect for nano tanks or systems where space and pressure consistency are key.

• Disc Diameter: 20mm
• Best For: Small to medium tanks and high-pressure regulators.

DY-N Series: The Versatile All-Rounder (Small & Mid-Dome)

The N Series offers the perfect balance. With a 20mm diameter and a shallow-dome profile, it provides a sleeker, more compact aesthetic than the C Series while maintaining superior diffusion over standard flat discs.

• Disc Diameter: 20mm
• Best For: 60L–100L tanks; provides a minimalist, modern look.

Small Stick-On Diffuser:
