I am using a Berlin on a 180 with good results. I'm sure there are more expensive skimmers that will do better, but the Berlin does a good job. I'd use a Mag 7 pump (if not a 9.5) on it. I don't much like the Aquaclear and you'll need about 4 Prizms for that tank. I have no experience with the Turboflotor although I have talked to people who were happy with them. My vote is for a Berlin or a Berlin XL and a slightly oversize Mag Drive pump.
