Key Features & Benefits

• Mesmerizing Spiral Bubble Counter: The internal glass coil allows you to watch individual CO2 bubbles travel upward before reaching the ceramic disc. This provides a stunning visual element while allowing you to accurately gauge and adjust your CO2 flow rate.

• Ultra-Fine Micro-Mist: A high-density 18mm ceramic disc expertly atomizes pressurized CO2 into microscopic bubbles. This maximizes the surface area of the gas, ensuring rapid and efficient absorption into the water column.

• Integrated U-Shape Design: The sleek, built-in U-bend seamlessly routes your CO2 airline tubing over the rim of your aquarium. This prevents the tubing from kinking and maintains a clean, unobstructed view of your tank.

• Secure Double Mounting: Equipped with two transparent suction cups and clips, ensuring the diffuser stays firmly and perfectly vertically aligned against your aquarium glass.

• Safe & Secure Packaging: Packaged in a sturdy kraft box with a custom-molded foam insert, guaranteeing your delicate glassware arrives safely and in pristine condition.

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 tubing, never apply sideways pressure or twist the glass stem. Soften the end of your tubing in a cup of hot water for 10 to 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 and the spiral is clear again. Rinse meticulously and soak in a heavy dose of aquarium water conditioner (dechlorinator) before placing it back into your tank.
