Is it a no brainer to switch out 2 emperor 400's for 1 FX5? The tank is a 125 with 2 400's 1 Eheim 2229 and a 30 gal W/D sump. There is 1 oscar 1 RTC and 1 Lima shovelnose.

But it seems like you have plenty of filtration allready.

But i would run the FX5 with the other filters to establish BB in the FX5. then run the FX5 in till the RTC out grows your 125gal.
