Aquarium Bubble Stone Ball Bubble Diffuser, Silent Diffuser with Control Valve to Dissolve Oxygen and Leave Very Small Bubbles for Aquarium and Hydroponics

Bubble Adjustable: If you need a very dense cloud of small bubbles, please adjust the air pump manually. The air volume of this nano aquarium bubbler can be adjusted via a control valve, resulting in a flow of ultra-fine bubbles and the bubbles released by the air stone are smaller, dense and more uniform, useful for fish in aquariums. Air pump accessories: the aquarium ball stone set includes a 35 mm nano air plate with non-return valve + suction cup (note: the air pump is not included). Perfect for your aquarium and a great companion for air pumps. Very quiet: The inflatable stone air aquarium diffuser has a very porous structure and its great breathability is impressive. Pneumolites can create very dense clouds of small bubbles. When air bubbles burst in the water, noise is reduced. Inside the aquarium, many small air bubbles are produced, creating an iridescent effect. Easy to install: with the help of suction cups, the ball bubble diffuser adheres firmly to the tank without taking up much space or reducing fish habitat. Durable and perfect for home, office aquariums, aquariums and hydroponic nutrient tanks. Note: Air Stone Cylinder Bubble Stone Before using the vent, please soak it in the aquarium for two hours to allow the vent to react completely with water. The shape of the disc allows optimal air distribution and stabilization. The non-toxic materials also keep the fish safe and healthy.
