Powerhead Positioning

[dragonfli]

i have noticed since i added 30lbs more LR, and repositioned my powerheads, that the current isnt hitting everything. i have dead spots in the water that dont seem to BE move.
i have a 55g and 2 power heads pushing 200gph=400gph and i thought that having one in the back right, and having the other in the front left pushing the current in a counterclockwise motion with all of the LR in the center. let me know of a more effective method, and positioning.
