I'm currently filtering my tank with two Filstar XP3s. My next fish will be an African butterfly fish, which (from what I gather) doesn't like a strong current. The other fish are cats, barbs, and an eel. They don't seem to mind current--in fact I think they like playing in it.
Right now, I have an XP3 outflow set up on both rear corners of the tank. The one on the left is facing in toward the center of the tank. The one on the right is oriented exactly the same way, so it's pushing water against the glass. This seems to create a nice circular current in the tank, without much turbulence. But I don't know if it's right for the AFB.
So, what's the right way to point two fairly strong filter outflows when you want to minimize current? How about when you want to maximize it? Can/should I look into extending the outflow pipes down toward the middle of the tank? They are pretty short and close to the water surface.
