Hey Josh, i helped set up a friend's tank and placed a big seio right in the middle pointing straight down between the two overflows. I would also point the powerheads in each corners point down so it will blow all the detritus out from under the rocks, and up the front glass and hopefully as much as possible into the overflows. At the very least it pushes the heavy detritus to the front where its readily available to be siphoned during water changes.
Of course this only applies on barebottom tanks. I think we had this discussion before when you were over and you are not a fan of BB tanks so this may not apply for you.
