Closed loop via powerheads?

[fishnet]

First off, thanks to many of you who post here regularly and help us newbies not spend a ton of money on future failures.
So, here's my question...
I'm planning on developing a sump/fuge system with a 20 long for my non-drilled 55 gal main tank. In addition, I am thinking about creating a closed loop for added circulation, but I want to spread out the flow (I'm planning on T-ing my returns from my sump so there will be two inputs -- probably a Mag 7 or 9.5).
Can I create a spreader bar by hooking up two powerheads to either end of a length of PVC with some holes drilled in it? Is this an acceptable solution? Got anything simpler/easier/more effective? I'm not so sure I want to go with a SCWD since I've read that a fair number of them are faulty.
Thanks for sharing.

You can create a "spray bar" with pvc, holes drilled in it, connected in the center from the return coming up from the sump. I don't think that ph's on each end of a spray bar would work.

I have this in my tank. a 390 GPH power head attched to a six foot length of pvc with very small holes drilled every six inches. it does cause some flow but it is very eratic and doesn't help much some holes flow great and some flow poorly. I had thought about adding another PH to the other end to get more flow but I think this would only make the set up even more eratic.
So to answer your question YES/NO it will work but not very good.
