Aqua-Life® Products run so quietly you'll forget you're aerating your bait. You'll know you are by the healthy condition of your bait. Aqua-Life® products feature a whisper quiet motor that runs efficiently at a low volume. Aqua-Life® products also utilize a special micro-bubble oxygen diffuser that produces clouds of tiny bubbles. Smaller more numerous bubbles mix readily as they collide and dispense through the entire water column. In bait containers, smaller bubbles are important as they are less prone to damage delicate baitfish. Each Aqua-Life® product includes the diffuser and a 30" non-kink air hose (Hoses and stones also sold separately as an accessory).
