I'm now using a couple of Koralia 750's for circulation and have placed them both right at the bottom of the aquarium in the back corners. They're hooked up to a digital timer so they take turns being on independently and simultaneously as well as both off for a few hours. The small base footprint and the large turnover creates a great upwelling of current from bottom to top.
The problem this much bottom current created is I couldn't use my existing Fiji pink sand as it was too fine and would be stripped bare in certain spots and piled up in others. I picked up some coarser reef sand yesterday and because I only needed 20lbs the difference in price between live and dead was negligible so I picked up the live.
The tank was pretty cloudy for the rest of the day but was crystal clear 18 hours later. Left a bit of a "bathtub ring" around the top edge but that was easily cleaned with a filter sponge.
