So, I have a 180 and am running 2 rena fx3's. I was thinking of a way to increase the holding power of beneficial bacteria. I came up with this drawing as a rough draft. Anybody done something like this?? any ideas why it may not work?? Any feedback would be great, good or bad.
No, I wouldn't suggest doing that. They are not meant to be run inline.
You can however setup a sump and use one of the XP3's as your return pump. It cuts down the GPH of the XP3 a fair amount but it will still push a good amount of water. I have done it before.

You could have both xp3's intaking from the tank, then have them output into a 4 inch PVC pipe filled with media. From there, a uniseal can be used on the pipe and you can put the output over the edge of the tank.
Though you get less spread of the flow in the tank (which can easily be remedied by a powerhead or so) you get more media space without a dramatic loss in flow.

The idea of using the bio chamber on the return line is a good one.
I would not use one as a return pump on a sump since they're designed to be gravity assisted. The pumps just circulate water through the canister and the downward force from the intake helps the pump "lift" it back to the top since it's essentially closed loop.
