Hello,

I currently have a 75 g with a 30g sump.
I have two Lifereef overflows and two Iwaki MD 20RLxt Pumps.

I would like to run another sump to add volume to the system with my other
( 3rd ) Iwaki pump.
Every scenerio that I can think of has a drawback.

Has anyone here done this before ?

Thanks for your help.
