Pan World on closed loop?

[ozzmosis]

Hello all! I am looking at using a closed loop on my 120. However, I have an idea that I want to run by you guys for confirmation before I proceed. I want major overturn of course, probably around 30x or better, with mass water movement, not a bunch of little streams here or there. I had planned to use my closed loop to give me all of my water movement. Therefore, not having to use any powerheads. I am drilling the back of my tank with 4 returns for my closed loop and I am planning on using penductors to increase the flow from the returns without having to use a huge pump and hopefully save on the electric bill a little. I was thinking using the Pan World 50P-Px which pumps 1110 gallons an hour @ 90w. From what I have read on premium aquatics about penductors, they are supposed to increase flow by 5 to 1. So, if that is the case then my pump would be pumping roughly about 5500 gph, if all of the returns have penductors on them (in theory). Therefore, getting mass water movement with a smaller pump and not using as much electricity. Does anyone have any experiences doing something similar? Do you think that it will work and be effective?
