Marine Metals Bubble Donut Air Diffuser

The Marine Metals Bubble Donut Air Diffuser is designed to deliver consistent, efficient aeration for live bait tanks, buckets, and livewells. Its unique donut-shaped design disperses fine bubbles evenly, increasing oxygen transfer while minimizing turbulence that can stress bait.

Built for reliability, the Bubble Donut produces a steady stream of micro-bubbles that maximize surface area for improved oxygenation, helping keep bait lively and healthy during transport or extended use. The compact, low-profile shape fits easily in a variety of containers without interfering with bait movement.

Compatible with most standard aerator pumps, this diffuser is a simple upgrade that enhances overall aeration performance and bait survival.

Perfect for minnows, shad, and other live bait applications.
