Hygger Stainless Steel CO2 Diffuser - Large

Overview

Built for high-performance planted tanks, the Hygger stainless steel diffuser delivers a fine, uniform CO2 mist through a replaceable ceramic disc while the rigid SUS steel body resists bending and corrosion for long service life. The classic curved bar hangs cleanly on the glass and anchors with suction cups for precise placement.

Features

• Durable SUS stainless construction outlasts fragile glass diffusers
• Precision ceramic plate produces consistent micro-bubbles for efficient dissolution
• Detachable diffuser cup allows easy cleaning or disc replacement
• Conical inlet makes airline connection quick and secure
• Low-profile curved design maintains a clean aquascape aesthetic

Installation & Use

Rinse, then mount with the included suction cups near moderate flow. Expect a brief break-in period where larger edge bubbles may appear for 1–2 days—this is normal and resolves as the disc wets in. Ensure the O-ring is seated and the cup is firmly tightened to prevent leaks.

Maintenance

If output slows or stops, remove the cup and soak the ceramic in a chlorine-based cleaner for ~20 minutes, then rinse thoroughly. Replace the disc when cleaning no longer restores performance.
