Description This is the Pollen Glass with a wider diffusion filter, which is placed on the side panel of aquarium. Its unique J-shape glass pipe design sits elegantly inside the aquarium tank. 20Ø is designed for 60cm tank with fully grown sun plants, such as Riccia that requires much CO2 and 30Ø diffuses CO2 effectively for 75-90 cm tank. Pollen Glass Large is made of glass including J-shape parts. Careful handling is required when attaching or detaching suction cup. Usage We recommend to use silicon hose to connect the glassware in order to reduce the risk of glass breakage. The piece of hose used should be kept as short as possible in order to avoid unnecessary CO2 losses.Silicone hose is not pressure resistant and therefore can not be used for connection to the pressure regulator.
