When I moved 3 hrs away. All I really did was I put all the sand in a 5 gal bucket and kept it submersed with tank water just to the top of the sand. I used a bunch of large coolers to put all my fish in with about half of the tank water with air bubblers running for the whole trip. kept all my bio-wheels submersed. All fish made it fine, some lost their colors but eventually settled down after a few weeks. As far as tanks go I just made all my bro-n-laws carry them. That's the benefits of having 6 bro-n-laws!
i made almost the same move. the coolers had thoes bait saver pumps with spray bars on them. it worked great. i had to set up a few tanks so i didnt get to them all at once. my africans lived in one for a few days just fine. the gravel stayed in buckets with water in them and same with the biomedia.
