gange valves and powerheads

Do Koralia p-heads oxygenate the water like other brands? I know there isnt direct oxy with others, but the bubbles help with surface agitation. The Koralia just looks like a propeller, so does it still produce bubbles? I've heard so many good things about the Koralia's, but my Loaches need a lot of oxygen.

koralias are more for creating current. if your aim the propeller at the surface, youll get good enough surface agitation to oxygenate the water
