I like fishing live bait particularly minnows. More so when winter fishing. I have tried a couple of different aerators, and they all seem to have a six month life span. I purchased the Engel 19 which came with its own aerator. When I get home, I have an aquarium aerator that I plug in, but when I go out, I depend on the battery operated. When I'm in my car, I use the car adapter to power it. Does the adapter do damage to the aerator? I would like to hear some input from OGF members on your experience with aerators, so that I can purchase an aerator that is a bit more reliable. Thanks.
