Mine has been going strong for about 4 years now....
I have also built a small aerator that runs off 12v that is perfectly silent and fully waterproof. Draws less power than my LED lights.
Has anyone used or bought one of those rapala aerators, which you just chuck into a live tank to keep oxygen going in? Reviews seem to be mixed. Thought it might allow herring to last a little longer without having to dump water in there and forgetting to turn off the pump and overflowing into the bilge, running down the battery, not being able to use pump when travelling, forgetting to turn it on again etc etc.
