How do you have it?

Hey everyone,
I have a 125 set up with a little over 100 pounds of live rock. My concern is my rock is all stacked along the back wall for the most part. I had several powerheads behind the rock structure but the cords running along the back wall looked really ugly. I am ordering two Rio-Powerheads rated at 740 gph each. If I put one in the top left/top right corner or my aquarium to you think this will be good enough. I am worried dead spots will build up behind the wall structure, how do you guys deal with this?

also a stupid question. on this site where the rio powerheads are located I have found several that say "UL Rated" and several that say fully submersible. I want to go with the fully submersible powerheads right?
Thanks

1fast,
For your 125g tank, you might want to go with a different powerhead. Ive heard a lot about the Tunze, Seio's and the Maxi-Jet mods (Google: MJ Mods). You may want think about them instead because they can give off much more flow and have a much higher tank turnover rate.

I second staying away from the Rio ph's. They are hit or miss when you shut off the tank for anything. Sometimes they will turn on, sometimes they wont. I personally use Maxijets because my wife will kill me if I buy tunze.

Thanks for the info guys. As for the rock structure.. how do you all deal with it stacked along the back wall? Does anyone have powerheads behind the rock walls in their aquariums or is it not a big deal.
Thanks
