i use the quiet bubbles too.in a 5 gallon bucket. shrimp, mullett, cocahoe and croaker (not mixed) seem to do fine for a days fishing. i had a recirculating system in a cooler once. didnt like it. sucked in the shrimp in the intake. or just otherwise beat them to death with the spray. if i going for an overnighter or if bait just been sickly of late i will take some water from the gulf, or where ever i am going to be fishing and freez it in ziplocs the night b4. keep it in the cooler and when it gets hot out i dump it in the bucket. if you dont have access to the water you will be fishing freeze some tap water in coke bottles then put bottles in bucket. DO NOT freeze tap water in ziplocks. they will find a way to leak and kill ALLL ur bait.
