Oase biOrb Bubble Tube Guard (MPN 46050)

The clear cap is designed to fit securely on top of the bubble tube, serving as a barrier to prevent shrimp, fish, and other objects from entering. Despite its protective function, the cap still allows bubbles to pass through thanks to the strategically placed holes. By placing the clear cap on the bubble tube, it safeguards against unwanted debris or creatures finding their way into the tube. Its secure fit ensures that there are no gaps or openings for shrimp, fish, or any other objects to enter. Moreover, the holes distributed across the cap's surface allow bubbles to escape, maintaining the desired bubble effect without compromising the cap's protective purpose.
