not to jump in and ruin things
but ill just tell you how I've moved countless tanks. Sometimes from 4 hours away on a uhaul. lol
When dismantling, carefully remove all coral and live rock and fish,
place them in buckets full of tank water, if you want extra tank water, simply take that out before you disturb the rock. you want it as detritus free as possible
DO NOT disturb the sand while you are doing this.
Once all the livestock is safely out of the tank,
drain it (the water will be clouded and 'gross' by then)
throw that water out. (the water in your coral buckets and the water you set aside before will be plenty)
DO NOT re use or keep the sand moist.
Scoop it out, and wash it, thoroughly.
Then put it back into the tank when you get to the new place.
When you get to the new place,
set the tank up.
Place the new sand in.
Add any new water/clean tank water you kept from before.
Let it settle for a bit, make sure temp/salinity/ph are all the same.
Add rock
then coral
then wait for a bit long
and add the fish.
The bacteria on the rock should be OK as long as you kept it submerged the whole time.
Will you see a cycle? Yup, guaranteed, any time you pull a rock out of the water some bacteria dies (not all, just a wee little bit, obviously getting worse the longer its out)
Your goal is to make sure its so small nothing is affected.
GOOD LUCK JEFF! moving is never fun, especially with livestock to worry about
