Looks like if you point that loc line downwards to the opposite end at roughly a 45 degree angle to get rid of the dead spot in the opposite bottom corner, you can then use a single ~800 (US gallon per hour) circulation pump to point up to the water line for surface agitation. I'm assuming the loc line output won't turn up the sand on the other other end like the circulation pump would. I would get a circulation pump that uses magnets to stick to side pane.
Ok, but if i point the loc line downwards where to point it to left or right, pointing the bottom? But it will blow all the sand, and where put the wavemaker? how many gph the wavemaker and what side? sorry for my questions
So you can experiment with the loc line right now before you get the pump. Point it to the other bottom corner, try the middle first. To see the flow of water, you could get some of the sand from the other end and drop it in the middle of the tank and see where it flies.. This will give you the idea of which side to point it down to (right or left or just middle). Afterwards just position it back to normal until you get the pump.
Now for the circulation pump, my first thought would be to use at least a 800gph pump, and put it on the same side as the loc line (about a 3-5 " below the water line) and see if you get the same amount of surface agitation as the loc line (before pointing the loc line down). You will then see if any of the sand rises. You could also simulate what will happen if a fish disturbs the sand bottom and see what happens to the sand if it goes up 3-4" from the bottom.

I actually like certain dead spots where detritus collects, especially if they are at an end where it makes it very convenient to siphon out.
I don't want detritus to collect in filters where it promotes the invisible nitrate to be returned with filter effluent.
I don't like them in an inaccessible spots, such as the middle in the back of the tank, those are the places Ill aim a circulation pump to eliminate.
I had a tank where I positioned flow, to form a dead spot on one end, that allowed for the only siphoning needed, to be in that spot (the tank was also sand bottomed)

Having fish poop collect under difficult to reach area just sucks. If you there is enough area to easily get the poop in the far back corner and have it not seen by other folks ( you know it's there so you can easily remove it every few days/week), then make sure that there is flowing water to the far end bottom (opposite end of the loc line) front pane of the glass.
Ok i guess ill have to play with the loc line and see where to point it at, cuz if i point to the middle of the glass i do have a rock on the other end of the tank and then it will be hitting the rock instead of glass, and avoiding to hit the sand directly and moving the sand all over the tank, but i will not have to much water movement at the top of the tank or surface.
