For a while I have been running my tank with a powerhead pumping air bubbles into the tank. My 26g tank does not have much sufrace area compared to the depth of the tank, and I have had issues in the past with fish appearing oxygen starved. I had the power head and the bubbles set low since I already had a couple filters in the tank. This was great for oxygen increasing surface aggitation, however the bubbles were getting annoying to look at, and sometimes fish would constantly try eating the air bubbles as if they were food. Watching a fish try to eat bubbles for 45 minutes is fun at first, but at some point you get upset that you own something so mindless
In and attempt to reduce the number of bubbles floating around in my tank, I turned off the air on my powerhead, lowered the flow rate on my AC200, and pointed my spray bar up towards the surface. I was not sure what to expect, but after playing with it, I have it angled it up at about a 40 degree angle. This creates a lot of current on the water surface, and if the water level drops below the spray bar, the water streams barely make it to the glass hood:
This combination has all but elimated any bubbles in tank, now it looks like my fish are floating around in the air
