NICREW Multi-Colored LED Aquarium Bubbling Stone Disk, Round Fish Tank Bubbler with Auto Color Changing LEDs

A built-in stone disk produces a curtain of the bubble to promote proper gas exchange. The 6 color-changing LEDs create a unique and striking light effect in any aquarium. Engineered with durability, this tube delivers steady airflow for quick and effortless inflation. Secure the LED disk with suction cups or place it on the aquarium floor with gravel. Allow Bubble Disk to soak for one hour before turning on air supply. If algae buildup reduces airflow after extended use, remove bubble disk from aquarium and clean surface with a stiff brush. Use more powerful air pump if the bubbler is not equally distributing. The volume and pressure output of your air pump will determine how large an area of the disk will release bubbles. For suction cups to adhere properly, the surface must be completely clean. We are dedicated to making fish keeping easier and more enjoyable.
