Moving tank long distance

so just a power head/air diffiuser should keep the water from going stagnant? no skimmer? Lucky it's only 29 gallons, so it'd fit perfectly into a 55g tub, I just wont have time to deal with it for a week. If I could get away with it, doing that versus setting up a another tank intermediately and to have it cycle again would be allot better. While having my fish/corals shipped down at a later time.
