20 cm Silent Aquarium Bubbler Air Diffuser Aquarium Air Stone for Pond Aquarium Bubble Bar for Pond Garden Circulation System

The main body of the pond bubbler is made of rubber, non-toxic and odorless, which does not release any harmful substances, thus ensuring the complete absence of danger to fish and aquatic organisms. Through a high-temperature sintering process, the distribution of the ventilation holes is uniform and delicate. The interface is made from pure copper with chromium plating process, which is anti-oxidation. The unique design of the microporous structure of the aquarium bubbler, combined with the highly permeable rubber substrate, allows for efficient and uniform release of gases. The air bubbles are fine and durable, which greatly increases the amount of oxygen dissolved in the water and effectively purifies the water. The air stone aquarium bubble is equipped with square brackets weighted on both sides and is heavy enough to easily sink underwater and prevent floating or turning over. Whether in ponds, hydroponic systems or large aquariums, it maintains a fixed position, ensures continuous and uniform release of air flow and operates quietly and smoothly without disturbing the aquatic environment. The ASE-301 is compatible with most oxygen pumps available on the market. The air inlet is suitable for standard air hoses with an internal diameter of 4mm or 8mm. Available in two sizes, 20 cm and 30 cm, it is recommended to use it with an air pump of 7W or higher to achieve the best oxygenation effect. It is recommended to soak for 24 hours or lightly sand the surface before use. The co2 aquarium diffuser is suitable for freshwater and saltwater environments, including large aquariums, outdoor ponds, hydroponic growing systems, ecological gardens and aquaculture bases. It is particularly suitable for large bodies of water with high requirements for dissolved oxygen, and is ideal for improving water quality and ensuring healthy growth of organisms. (Note: not recommended for small aquariums)
