【QUALITY】: Aquarium CO2 atomizer made of aluminum alloy, nickel-plated after oxidation treatment, acid and alkali corrosion resistance, durable. 【FUNCTION】: The diffusion plate decomposes CO2 into tiny streams of bubbles, dissolves it in the water, and then allows plants to absorb CO2 for photosynthesis. 【HIGHLY SEADLED】: Make sure to tighten the top threaded port, press the suction cup tightly to make it fit tightly to the surface of the aquarium sidewall, to achieve the best atomization effect. 【PERFORMANCE】: The high-density aquarium atomizer produces small bubbles (diameter less than 0.1 mm), which increases the dissolution rate of carbon dioxide, which is not easy to block the aquarium. 【EASY TO CLEAN】: Open the top diffuser cup cover to replace it. It is recommended to clean once a week to prevent bacterial growth. Installed directly under the aquarium. Also suitable for low voltage systems or CPU-controlled systems and 20-40L aquariums. Features -The U-shaped design is more practical than ordinary filter tubes. -The length can be adjusted freely according to the height of the aquarium. -The CO2 aquarium atomizer can still work normally when the carbon dioxide cylinder is under full pressure. Working Principle The diffusion plate breaks down the CO2 into tiny bubble streams, dissolves it in the water, and then allows plants to absorb the CO2 for photosynthesis. Specification Material: Aluminum Alloy Quantity: 1 Color: Silver Height: 6.2 cm Diameter of the Suction cup: 2.5 cm Diffuser: 2.3x1.5 cm Total weight: 26g Warm Tips -The size of this aquarium CO2 diffuser is small, please refer to the size to purchase. -When the aquarium CO2 atomizer starts to work, bubbles will accumulate and disappear after a few hours. This is the normal working principle, please don't worry. Package Contents 1x Aquarium CO2 Atomizer
