I would run that AquaClear as well; they rock - very handy. A 300 is more than big enough for that size tank, and can hold a variety of materials with ease of access. Mine holds a sponge (full of baby brittle stars) and a bag of carbon or Chemi-Pure.
People use the big ones too, for mini-refugiums sometimes, or to hold some algae and live rock, you name it. They have good flow, low power consumption, simple construction... and without the common problems sometimes associated with cannister filters.
