Floating Crypts and Such (Temporary)

[Rokuzachi]

Have any of you ever had to float crypts for a while? Or a Sword?

I'm presently in the process of moving and need to break down one of my planted tanks a bit in advance so I can make the move all in a day. How long do y'all think I could float a host of Crypt. Wendtii for under a 24w in an established tank without messing up the whole lot of it? I also have a melon sword that needs to move.

Thanks!
