Advise On Canister Filter Setup, Layout, and option?

So you put both intakes on the left and have both exit on the right? this would increase the house length for the exit. Wouldn't I loose head pressure pushing the water out?

You may but I believe this depends more on the return then intake as you are battling gravity with the pump return but with the intake gravity is on your side

If you are returning to both ends that it may be that one intake on the left is only ever going to be cycling filtered water - the most efficient would be to ensure the intakes are placed where most of the debris would be collected
