moving tank

I'm having new carpet installed and need to move my 26 gal bow front
tank on a 28 inch high wood stand to another room. I'm thinking of
draining the tank down to about 3 inches, slip "furniture slides"
under the stand and moving tank and stand all at once leaving the fish
(2 bala sharks, 2 black tetras all small) in the tank. I'm guessing it
will be no more than 20 hours untill I get the tank back in the living
room and refilled.

Will the fish be ok in that amount of water and with no filter
running? I want to save about 10 gal of that water in buckets, will
it be ok to pour that back in?
