What kind of filter do you have now, and how is it baffled?
If it is an HOB filter or a lid type filter, the water is exposed to air and agitation inside of the filter. Instead of adding a different type of aeration, you can work with the baffling to make movement below the surface to circulate the water.
On my male's tank, I used a modified version of that plastic cup sticky to aim the water to the nearest corner - there is a tiny bit of agitation there, and the water circulates around the whole tank below the surface. It doesn't bother him at all, and he builds huge bubble nests every day.
