Moving a reef tank...

[fishbait]

again - thanks for the input... but a further question about the sand.
How much is "deep" (>6inches)... and why start new with this much?

Also, I 've read different oppinions about how fast to add the LR after the move... one author says to go slow and add the sand after a few days and the rock in a week, another basically says... "go for it"...(same day once the water is in and the temp/PH are within limits.
If the LR transports well, is there any way to really screw it up by adding it to the tank too early?
