240 Gal peninsula

[jerrod]

I've had a 240 gallon peninsula running for about 2 years and am not happy with the flow/ detritus settling. I currently have 3 Current USA 6006's on the back wall (2 blowing across and 1 towards the bottom blowing up at an angle) and 2 maxspect gyre 350's running vertical in opposite corners and am still having issues with getting detritus to flow all the way back to the overflow without settling. I Have plenty of flow and corals are doing well just seeing if anyones had the issue before and what there solution was as I want to improve. Below is a real quick sketch. Any ideas is appreciated

Do you have any pictures of the aquarium and rockwork? That will help us determine where the inhibition or lack of flow is coming from.
