I've been using a Elite 799 5 gallon air pump in my 50 gallon tank, the air pump vibrates a lot so I've put it on a towel to prevent it from moving. It makes a slight hum that bothers me at night since it is in my room.
I've just bought a air stick? About 10 inches long and when I plug my air pump in it, only the side I plug it into bubbles instead of the whole bar (the bar is leveled, flat on the bottom of my tank).
I'm guessing that I need a stronger air pump to be able to fill the bar up with air. I've used the Elite for about a year and I would like any suggestions on a good silent one. Should I get a 10 gallon air pump this time to make the whole bar fill up?
Thanks!!
