I got an FX-5 for my 75G goldfish tank. I was sick and tired of servicing two large HOBs on weekly basis, and the giant canister has me down to about ever three weeks between filter maintenance. This is with 9 Goldfish of decent size, plus supporting dojos and pleco.
I was concerned about the output wash as well, but I'm surprised how unphased everybody is in the fast-moving water. Granted, my most delicate fish are fairly hardy ryukins. The loaches rather enjoy playing in the filter wash. The intake is also quite well designed, with almost no suction that I've ever noticed.
