【QUALITY】: Aluminum alloy CO2 atomizer, nickel-plated after oxidation treatment, acid and alkali corrosion resistance, durable. 【FUNCTION】:The diffusion plate decomposes the CO2 into tiny bubbles streams, dissolves it in water, then allows plants to absorb CO2 for photosynthesis. 【HIGHLY SEADLED】: Make sure to tighten the top thread connector, firmly press the suction cup to firmly fix the surface of the side wall aquarium to achieve the best atomization effect. 【PERFORMANCE】: The high-density aquarium atomizer produces small bubbles (diameter less than 0.1mm), increasing the dissolving speed of carbon dioxide, which makes the aquarium not easy to be blocked. 【EASY TO CLEAN】: Open the top cover of the cup of the diffuser 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 processor controlled systems and 20-40 liter aquariums.
