Just a couple quick notes on this awesome filter I just purchased and set up. I am very impressed with the quality and features of this unit. Set up was a breeze with the included media, and I'm hoping my "11" serial number will be free of the past leaking problems that plagued some of the pro III line.
Anyway, for people doing research on buying a new filter, I am getting 190gph with nothing in-line. I have it on a standard 29gal tank and the flow is in no way too strong. In fact, I would hesitate to put this filter on a tank much bigger than this. None of my fish have in any way altered their usual hangouts developed during their tenure with my previous filter (a Penguin 200). I bought it for ~$150 on a pretty popular website and I think it was a fantastic value at that price.
I did a lot of research on here before buying my filter, so thank you to the community for their filter input!
