ADA Pollen Glass Beetle Series

ADA Pollen Glass Beetle Series

The ADA Pollen Glass Beetle Series represents the pinnacle of high-output diffusion technology for serious planted aquascapers. With its distinctive wide-body Beetle design, this series maximizes the diffusion surface area to deliver an exceptionally dense, even spread of ultra-fine bubbles — whether you're running a pressurized CO2 system or supplemental aeration. Available in three disc diameters (30Φ, 40Φ, and 50Φ) for both CO2 and air applications, the Beetle series scales to meet the demands of any large or high-tech aquascape.

Pollen Glass Beetle 30Φ (CO2)

The entry point to the Beetle series, the 30Φ CO2 model delivers powerful CO2 diffusion in a compact Beetle form. Ideal for medium-to-large planted tanks running pressurized CO2, it produces a rich mist of micro-bubbles that dissolve rapidly for efficient plant uptake.

• 30mm ceramic disc for high-density CO2 micro-bubble output
• Beetle body design maximizes diffusion surface coverage
• Suited for medium-to-large planted aquariums
• Compatible with standard CO2 tubing and ADA regulators
• Premium borosilicate glass — made in Japan

Pollen Glass Beetle 40Φ (CO2)

Stepping up in output, the 40Φ CO2 Beetle is engineered for larger aquariums and demanding plant communities. Its wider disc produces a broader, denser curtain of CO2 micro-bubbles, ensuring thorough saturation across a greater water volume.

• 40mm ceramic disc for broad, high-volume CO2 diffusion
• Ideal for large planted tanks with high CO2 demand
• Produces a dense, even micro-bubble curtain for maximum dissolution
• Compatible with standard CO2 tubing and ADA regulators
• Premium borosilicate glass — made in Japan

Pollen Glass Beetle 50Φ (CO2)

The flagship CO2 model of the Beetle series. The 50Φ is built for the most demanding high-tech planted aquariums, delivering unmatched CO2 diffusion coverage across large tank volumes. When your aquascape demands the best, the Beetle 50Φ delivers.

• 50mm ceramic disc — the largest in the Beetle CO2 lineup
• Maximum CO2 diffusion coverage for large, high-demand aquariums
• Ultra-fine micro-bubble output for superior CO2 dissolution efficiency
• Compatible with standard CO2 tubing and ADA regulators
• Premium borosilicate glass — made in Japan

Pollen Glass Beetle 30Φ (Air)

The 30Φ air version brings the Beetle's signature diffusion quality to aeration applications. Perfect for overnight oxygenation, CO2 off-period aeration, or fish-forward setups where fine, consistent air diffusion is essential.

• 30mm ceramic disc for fine, consistent air bubble diffusion
• Ideal for supplemental aeration in medium-to-large aquariums
• Produces fine, even air bubbles for efficient gas exchange
• Compatible with standard airline tubing and air pumps
• Premium borosilicate glass — made in Japan

Pollen Glass Beetle 40Φ (Air)

The 40Φ air Beetle scales up aeration output for larger tanks. Its wider disc delivers broader air diffusion coverage, making it an excellent choice for heavily planted or stocked aquariums that require robust, consistent oxygenation.

• 40mm ceramic disc for high-coverage air diffusion
• Suited for large aquariums with elevated aeration needs
• Fine, even bubble output for thorough oxygenation
• Compatible with standard airline tubing and air pumps
• Premium borosilicate glass — made in Japan

Pollen Glass Beetle 50Φ (Air)

The ultimate aeration diffuser in the Beetle series. The 50Φ air model provides maximum-coverage fine-bubble aeration for the largest aquariums and most demanding oxygenation requirements — delivering a sweeping curtain of micro-bubbles across the entire tank.

• 50mm ceramic disc — maximum air diffusion coverage
• Best suited for very large aquariums or high-stocking setups
• Dense, fine bubble output for superior oxygenation efficiency
• Compatible with standard airline tubing and air pumps
• Premium borosilicate glass — made in Japan
