Installation & Maintenance Pro-Tips

To achieve the finest CO2 mist and protect your fragile glassware, please follow these essential steps:

The Crucial Pre-Soak: > Before attaching your CO2 line, submerge the entire diffuser in aquarium water for at least 24 to 48 hours. The ceramic disc must be completely saturated with water to produce a fine mist. If connected while dry, the gas will escape as large, inefficient bubbles.

Handling with Care: > Glass CO2 equipment is delicate. When attaching or removing your silicone or polyurethane CO2 tubing, never apply sideways pressure or twist the glass stem. Soften the end of your tubing in a cup of hot water for 10-15 seconds first—it will then slide safely and effortlessly onto the glass inlet.

Routine Cleaning: > Over time, algae and natural biofilm will clog the microscopic pores of the ceramic, reducing bubble efficiency. To clean, soak the diffuser in a mild bleach and water solution (1:10 ratio) until the disc is bright white again. Rinse meticulously and soak in a heavy dose of aquarium water conditioner (dechlorinator) before placing it back into your tank.
