Fx5 is awesome, best canister on the market hands down. In a 125 you will still need another filter, at the least a powerhead but the return hose has 2 heads pointed in opposite directions you can adjust for where you want flow. If you go that route, make sure you keep note its not sold with filter media unless the website specifically says so. It comes with the sponges but nothing for the trays.
