Whereas the Pollen Glass Series has been designed for standard 60 cm aquaria, the Pollen Glass Beetle Series fulfills the CO2 demand of aquaria with a length of over 90 cm. To cover the high CO2 demand of aquarium plants, a large diffuser is required, which enables the CO2 to spread in the tank evenly and effectively. The singular form of this Pollen Glass Diffuser has been designed on the form of the African stag beetle, and it becomes almots invisible when installed in a corner of the tank. We recommend the use of the multiple-use Pollen Glass Beetle unit for injecting CO2.
Recommended for an aquarium size of approx. 90 - 120 cm
