What do you currently have for circulation?
My biggest concern about CL's is that the pumps tend to have a heavier electrical draw than powerheads. A little easier to hide the hardware though, I suppose, plus you can have eductors. But the one nice thing about things like Tunzes is how ridiculously little electricity they use.
