Since this is just a 20gal tank, I've been using a Hagen. I just ordered one of the following. I'll see how it goes.

Looks neat. I like the mounting arrangement.

If it's too powerful for my 20gal, I'll put it in one of my bigger tanks.

Well, I bought the smaller Tunze (IIRC, 1600 gph). I was worried that the larger
one would be too much flow for my 125. Now I wish I had opted for the larger
one. I may pick up one of these units an put it down at the opposite end of the
tank from the Tunze.
