The Marine Metal Bubble Donut Air Diffuser keeps bait lively and maintains high oxygen levels for every trip. Available in 3-inch and 5-inch weighted glass bead sizes, this durable diffuser connects easily to any standard silicone air line used with portable aerators. Once submerged, it stays securely on the bottom of your bait bucket or livewell, producing fine, even bubbles that deliver consistent oxygen dispersion for minnows, shrimp, and other baitfish. A one-hour pre-soak before first use ensures maximum performance and long-lasting efficiency in both freshwater and saltwater environments.

• Weighted 3" or 5" glass bead diffuser stays on the bottom for stability
• Produces consistent, even dispersal of dissolved oxygen
• Compatible with most standard silicone air lines and portable aerators
• Requires a 1-hour pre-soak in water before initial use
