Yes, it can be moved in a day. How old is the substrate in
the 29g now? If it is under 6 months old, you can move that
to the new tank. If it is older, it would be better to
set up new sand and take a couple of cups of the current
substrate to seed the new tank.
Move over all the same water, LR and creatures, and add more
saltwater that was mixed for 24 hours, matching
temperature and salinity exactly.
If you want to read the gory details of how I transferred my
29g and 55g to my 280g, here is the lengthy thread on Reef
Central.

Feel free to skip ahead to Day 13, probably around page 26?
