Moofey 2 PCS Aquarium Wood Air Stones, Wooden Fish Tank Bubbler Stones, Air Bubble Diffuser for Pond, Hydroponic, Circulation System

Delicate Bubble Diffusion: These aquarium bubbler stones can generate small and uniform bubbles, improve oxygen dissolution efficiency, and effectively increase the dissolved oxygen content in water Impurity Separation: The pores of wood aquarium air stone can filter particles in water, which helps maintain clearer water quality during the process of generating bubbles Air Pump Compatibility: Air stone needs to be paired with an air pump of less than 5W, as using an air pump with excessive power may cause premature decomposition of wood fibers and reduce diffusion efficiency Universality: The air stone is suitable for aquariums in both seawater and freshwater environments. It is recommended to replace it every 2 to 3 months based on the biological load and usage intensity for optimal results Material: Fish tank air stone is made of wood, with a soft touch, lightweight, and porous structure to maintain bubble stability, making it comfortable to use
