BLOTFISH Aquarium Bubbler Air Stone – 4 Inch Fish Tank Nano Quiet Dissolved Oxygen Diffuser Make Super Tiny Bubbles for 35-100 G

Quiet Tiny Nano Bubbles: The oxygen stone refines the air output from the air pump into fine gas bubbles, making the bubbles smaller and denser. This increases the contact surface area and exchange rate between air and water, providing ample oxygen for the fish without generating excessive noise | 4 Inch Air Diffuser Area: recommended air pump power 3w-8w, suitable for freshwater and saltwater aquariums ranging from 35 to 100 gallons. Note: If the water is deeper, you may need to choose a higher-powered air pump to ensure optimal performance (air pump are not included) | High Dissolved Oxygen Rate: This air stone is sintered at high temperature, release smaller, denser, and more uniform bubbles, effectively increasing oxygen levels while reducing carbon dioxide levels in aquariums, fish tanks, and hydroponic systems, and raising the pH value | Dirt-Resistant for Long-Term Use: It is easy to clean and can be used for a long time and has better dissolved oxygen effect. When the small bubble burst into the water, the sound is super quiet (Note: regular cleaning helps to ensure optimal performance.) | Great Accessories for Air Pump: this aquarium air stone kit includes a 4 inch Nano Air Disk Stone, 1 Control Valve, 2 Suction Cups, 1 T-Shaped Connector and a 2m (78.2 Inch) Airline Tubing.
