Micro powerhead

[Ordovician_Reef]

One of the few design flaws in the Waterbox sump is a stagnant surface in the transition from the back overflow slot into the filter socks box. I am looking for a micro powerhead, I mean small with VERY low flow. It must be 2 inches of less in width and have minimal flow.

Any ideas ?

I use this guy as an additional powerhead in my 15. It's small and has a low setting.

The Aqamai KPS is the size of an egg, I use it in my 15 gallon, good quality powerhead, and controllable.
