Marineland 93 cube stand

[Winschuc]

Picked up a 93 rimless and stand the other day. The top of the stand is completely open and it scares the (expletive) out of me. Has anyone had issues with these stands, or is it recommended that I add a piece of ply to the top?

Side note - I'm aware of the seam bubble issues with these tanks, filling it up soon to see if there are any issues. Mainly curious about the stand at this point.

Thanks!
