Product Description
The Hygger 8cm Invisible Nano Air Stone combines practical aeration with an elegant, discreet design. Manufactured from clear acrylic with stainless steel weights, the air stone sits securely at the bottom of your aquarium while remaining almost invisible beneath the water. Simply conceal it behind rocks, plants or ornaments to enjoy a beautiful display of sparkling bubbles without distracting from your aquascape.
Its durable EVA air diffuser produces two attractive rings of fine bubbles that efficiently oxygenate the water and improve circulation, helping to create a healthier environment for fish, shrimp and aquatic plants. The high-quality construction is designed to resist clogging, providing reliable, long-lasting performance with minimal maintenance.
Installation is quick and straightforward—simply connect the air stone to a standard 4/6mm airline using an aquarium air pump (not included). For optimum bubble production, Hygger recommends using an air pump with an output of approximately 2 litres per minute.
