even though I love vortech's, Id go with a combo of vortec and tunze for your tank as I did with mine.
you can put a tunze 6105 [controllable] on the left side of the tank, and put it right at the top left corner, right by the wall, as high as you can place it to avoid the wire and also open up view. point it across the tank, tilted towards the front or back depending on the rock work.
then 1 MP40 on the right side of the tank. And make a little canyon with your rock work, and place the 2nd MP40 on the back glass where the canyon is ... around 2/3 of the tank ...
for the MP on the right side ... if u need more flow, u can make that a MP60 ...
in my tank, 6x2x2 I have 1 MP60 on a side, 2 MP40s on other side[one in front of rock work, another behind the rock work at the bottom] , and a tunze 6105 on top corner as I described above. before my move it was MP60 on one side, MP40 and 6105 on other and another MP40 on the back glass for the canyon.
dont want to ruin your thread with my low quality pics, so here are some links to pics
