I moved my 33g from Victoria to Kelowna 3 months ago and I didn't loose a single fish or coral. (total drive/boat time was just over 7 hours!) Here's what I did...
-I used 2 large Rubbermaid containers for the move
-1st one had all the live rock (that didn't have corals attached to it) and about 60% of the tank water
-the 2nd bin had all my corals and fish ...and about 20% of the water. I individually packed my stinging LPS in Tupperware with holes in the lid.
-the remaining 20% I removed and added new when I arrived in Kelowna (water change)
-I bought battery powered air bubble pumps but I only used them on the ferry ride to Vancouver... my driving created enough surface movement for oxygen transfer lol
-I left the sand in the bottom of the tank with enough water to keep it wet and "alive"
-as soon as I got to our new place, I quickly set up the new tank ...everyone is all in the same water, so I didn't need to acclimate or anything. Just a quick aquascape and set up
I thought I would loose something on my 7 hour trip but I didn't
Good luck!!
