This is the one I have on my 10. I like it because it's adjustable. I have never had a problem with it & it comes with a good set of accessories like hangers & stuff. It's a Hagen 201 rated at 125 GPM.
My brother has the Hagen 301 and loves it. However, how much smaller in size is the 201? I dont what to have a really large powerhead in there since its a 10 gallon. How big is yours in your 10?
