1. Hook Design: The diffuser can be easily fixed on the wall of the fish tank through the hook. Installation and disassembly are very convenient, allowing users to adjust the position of the diffuser according to their needs. 2. Efficient Bubble Counting and Refinement: It can accurately calculate the number of carbon dioxide bubbles and efficiently refine carbon dioxide into tiny bubbles, improving the diffusion effect of gas in the water and meeting the carbon dioxide needs of aquatic plants. 3. Guarantee of Glass Material: Made of glass material, it has good chemical stability, will not have an adverse effect on the water quality, and can clearly observe the internal refinement and bubble generation process.
