The Pollen Glass Large with a diameter of 30 mm is available for larger tanks to fulfill the CO2 demand of your aquarium. We also recommend the Pollen Glas Large Series for aquaria with a high stock of plants like Riccia fluitans, which needs large amounts of CO2 to grow healthily. The U-shaped glass tube is almost invisble and prevents congestions. Hand-made all-glass diffuser, designed for long-term use.
Recommended for an aquarium size of approx. 60 - 75 cm
