Tool to remove larger rubble from sand?

Hey everyone...  My sand over time has lifted the larger rubble bits to the top.  I would rather most of the bottom be actual sand...  The tank is pretty deep so I really need a rake/basket to reach down in with to sift out the larger bits and leave the sand behind... Is there anything commercially available or will I need to bust out the CAD program and the 3d printer?
 
Well, since I got no response... I designed one.. its on the printer now!
