Parts List: 1 x Air Stone Highlight description: [Premium Materials and Innovative Bubbling Technology] Our premium column-shaped bubble stone, crafted meticulously from a blend of superior materials including rubber, plastic, and metal (featuring a pure copper, zinc-plated air tube connector). Setting it apart from conventional sandy airstones, this cylindrical aquarium aerator boasts advanced manufacturing techniques, resulting in thousands of micro-pores on its surface. These pores efficiently disperse air into the water, facilitating the effective dissolution of oxygen, ensuring higher dissolved oxygen levels through its innovative bubbling technology. [Dimensions] Measuring approximately 20cm in length, with a base side length of 4cm, and a metal connector diameter of 0.5cm, it fits standard 3/16" and 3/8" (inner diameter) air hoses through its stepped metal interface. [Finer & Abundant Bubbles] Unlike traditional sandy airstones, this bubble diffuser produces finer and more abundant bubbles, significantly enhancing the oxygen concentration and stability within your aquarium's underwater environment. (Reminder: For optimal bubble output, consider using an air pump with higher flow rate and pressure.) [Stable Placement] Designed with built-in weight and square bases at both ends, this aquarium bubble stone securely anchors itself to the bottom of your tank, resisting displacement caused by water currents or fish activity. [Anti-Clogging Design] Its innovative anti-clogging design prevents clogging, saving you time and effort, making it the ideal choice for aquariums, ponds, fish farms, and other aquatic environments. Detailed description: Description: You can elevate the oxygenation and vitality of your aquatic ecosystem with our innovative aquarium air stone. This air stone incorporates advanced bubble technology that delivers exceptional performance, ensuring a higher level of dissolved oxygen in your water. Key Features: Innovative Bubble Technology: At the heart of this bubble stone lies its innovative technology, which generates finer and more abundant bubbles than traditional airstones. These micro-bubbles disperse evenly throughout the water, significantly increasing the dissolved oxygen concentration underwater, fostering a healthier environment for your fish and aquatic plants. Enhanced Oxygenation: By producing smaller and more numerous bubbles, this air stone maximizes the higher levels of dissolved oxygen. This not only benefits the respiratory health of your fish but also promotes the breakdown of organic matter, maintaining water clarity and overall water quality.
