I'm getting a 125 aquarium to put my goldfish in. I have an Eheim 2080 I'm putting on it that should have no problem taking care of the bio filtration. From what I had used it before the mechanical filtration seems to be really lacking though. I was curious of a filter suggestion to supplement the 2080 to help with mechanical. This aquarium is going in my bedroom, so I'd like it to be as quiet as possible. I was considering an fx5, since the one I have is such a good filter. My only concern is my wife has an oranda goldfish that's between 4 and 5 inches I don't want bouncing off the sides, because of to much current. Thanks for the help.
Filter advice for a 125 gallon goldfish tank.

I have 2 Rena XP3's on a 150; 1 purely loaded with bio and the other loaded with mechanical and my water is really crispy. You could also add a powerhead with a sponge to really increase mechanical filtration - just clean it regularly.
try a cfs 500 off of ebay for 59 dollars for the mechanical filtration. I have one on mine and its great
I'd say just go with the Fx5. I don't think the current will be that strong. I have 2 on my 120g. On a 125g, it's a longer tank and the current should be just fine for it.
I concur. I put mollies in my 125 and they would swim a couple inches from the return and were barely affected by the flow.
DE filters are the best mechanical filters I know of... Nothing else I have used is capable of clearing up cloudy water like a DE filter. My Magnum 350 never came close to matching my DE for water clarity. To me a DE is worth their hassle.
I have taken DE filtration to an extreme for an aquarium though:
