Does this exist???

So, I'm trying to find a specific type of powerhead but I'm not sure if such a thing exists or if I'll need to rig something on my own. I'm looking for some sort of powerhead thing that I would be able to mount on or by my drain pipe in the back of my tank (which is exactly center). I would want this powerhead to then spray in opposite directions towards the two ends of my tank. I am just not getting enough flow in the back and its causing a bunch of junk build up which is not helping with my new hair algae issue. Plus I want more flow in my tank overall. So, does anyone know anything like this that exists? Or would it just be easier to rig two koralia's facing opposite directions?

Thanks,
Kylie
