That's all I'm running on my 10gal. Granted I am only in the cycle stage (tank was set up last weekend). If you have the prefilter you can always put carbon in there.
I'm not sure how my set-up will turn out. I figure I will experiment w/ this and see what happens. But, so far, everythings going great. Oh, yea, you can also use the return chamber of the Remora to put a heater in. I have an Ebo-Jager 150w in mine (keeps equipment out of the display) and it keeps the water at a constant 78-80*.
