Yes, i'm setting up 2 tanks, and small beause I'm interested in extra small nanos. I've seen people mainting 1 ft using nothing except hang on filters. That's good in my opinion as it serves 2 purposes - filtration and aertion, but they cause salt to spray out. dirties the surroundings and causes damage to nearby items.
Was wondering if there's another alternative, but in such a small tank, a powerhead might cause too much turbulence.
