The Cool Bubbles bait bucket kit includes an extra thick foam liner for the insulated bucket with rope handle and a Bubble Box aerator. This exceptional, easy to use Bubble Box aeration pump comes with 24 inches of airline tubing and a weighted air stone for use in any bait bucket up to 5 gallons. It is designed to work in both fresh and saltwater and is great for ice-fishing. Key factors for keeping bait fish, minnows and shrimp alive and lively include proper aeration, water temperature maintenance and controlling water acidity. The cool bubbles insulated bait bucket kit with air bubbler is ideal for proper aeration and maintaining constant water temperature; changing the water in the bait bucket and removing dead bait helps control acidity. The precision motor on the bubble box runs approximately +/- 44 hours on 2 alkaline D batteries (not included) but will also operate +/- 22 hours with just one battery. The aerator pump provides 1.4 STL of air/minute.
