125 filtration (I know, one of the hundreds.. :/)

  • We are currently upgrading MFK. thanks! -neo
Sump would be great if you get it running, but the fluval should work as long as you don't go nuts and get a ton more stock
 
I would go with the FX5, much better option. I have 2 405s on my 75 and wish I had an FX5, much better filtration.

I wouldn't do the sump, in FW a canister is a much better option.
 
I don't think so. Even if bio was enough, oscars are messy fish and may leave a lot to be desired in the way of mechanical. Details on the sump? Gallon, pump, turnover etc??

EDIT reptileguy beat me to it.. I also run an FX5 on my 125 gallon and have other filters running as well.
