You might want to buy one of these for your powerhead to see if it helps. http://www.marinedepot.com/ps_viewi...tent=HD01401&gclid=CPKjpOW51LwCFUNffgodjVQASw
They are great little gadgets for $10 and great for a nano.

You mount it on the return of your current pump. The water flow makes the deflector spin around to you are not blowing water in just a straight stream.

No electricity. Solely on the output of the pump. I used one of these in my former Nano and it was great.

If I remember correctly it comes with a bunch of adaptors. But I forgot to mention I'd ditch the 50 pump and go with 100 or so. The 50 is like a gentle breeze.
