Maintaining back corner of a cube

[Gobigorgohome_]

To those of you with large cubes (60, 93 gal etc) in a corner position,

How do you maintain the back corner of your cube?

I am considering something between a 60 and 93 cube to put in the corner of a room under where the stairs are. I made a mock up with a box and I can barley reach the back corner of a 60cube with my finger tips, let alone anything bigger or with water and rock inside it. Now I'm not a tall dude with a particularly long reach admittedly, but there must be some trick to this?

Do you just use a rake for your sandbed and some sort of tool with your corals? or do you space your scape off the back a bit and have a bit more careful placement?

Thanks

I don't know about a cube but in hard to reach areas of our tank we use this tong like device. Think the shark head at the end of a long stick where you pull the trigger so to speak and it makes the mouth close. More sturdy than that but same concept. I'll ask my wife where we got it when she wakes up.
