The diffusion plate breaks the carbon dioxide into tiny streams of bubbles, which are then easily dissolved in water, allowing plants to absorb the carbon dioxide for photosynthesis The diffuser made of stainless steel is durable, unbreakable and non-toxic for your pets and plants. The ceramic disc is replaceable, easy to disassemble and replace, please tighten it when installing Suitable for aquariums with wall thicknesses up to 18 mm The total length of the J-tube is 40 cm. Ceramic disc diameter 36mm, CO2 diffuser for standard CO2 air pipe 4*6mm (inner diameter 4mm and outer diameter 6mm) carbon dioxide diffuser It is absolutely It is essential for aquatic plants to ensure a sufficient supply of carbon dioxide in the aquarium, as carbon dioxide provides them with the carbon they need to survive. A carbon dioxide diffuser provides sufficient carbon dioxide to the aquarium. reduce carbon dioxide loss Fine foam, easy to clean Significantly increases plant photosynthesis High-quality stainless steel and state-of-the-art ceramic technology proposal: We would like to point out that the plate diffusion must be activated and the accumulated CO2 bubbles exert a certain initial pressure; therefore, more CO2 is released into the aquarium when activated. Wait until this effect stops and do not increase the number of bubbles - otherwise you will have to decrease the number again bubbles afterwards. Use a permanent CO2 test system to check the CO2 level in the aquarium. Adjust the amount of CO2 in the aquarium by increasing or decreasing the number of CO2 bubbles. The ceramic diffuser disc is a consumable. The lifespan varies depending on the type and growth rate of algae in the aquarium. The maintenance period is generally 7 to 60 days. If there are a lot of algae growing on the ceramic plate, the bubble diffuser will not generate external CO2 or the bubbles will become bigger, you can soak in 84 disinfectant overnight.
