Maybe buying a 300 gal setup...moving questions

[ShadowWynn]

So, a bit of background...I had a 175 bowfront tank with sump setup 12 years ago before I moved to my current place. Had this for a good few years successfully till I parted out the system due to moving. Time to get back in...

I am looking at purchasing a complete 300 gal setup with everything in the tank. I would need to go several hours to get this tank and all the occupants. I have the truck. I have the trailer. I plan to get a food grade cube to transport the water, at least a good chunk of it. So my questions...
1) Beyond the aeration issues of transportation of fish, is there anything else I need to know going long distance? FYI- will be crossing a state line.
2) Refilling the tank with the same water should cut down on spikes, right?
3) I know to leak test the system after assembly. Other than this and temperature leveling, am I forgetting anything? It's been a while since I assembled a system.
4) Am I insane for buying a complete system vs creating a new setup?

So water contains significantly less bacteria then the rock and media in your tank. So water alone will not be able to breakdown fish waste. If you are making the move in under 24 hours then I wouldn't worry about ammonia building up. Just have a good amount of fresh mixed saltwater at the final destination. The type of fish and volume of water would give a better idea.

When moving the tank try to have some padding under it so the vibration is not going through the seams.

Personally what I would do is already have a tank setup and cycled at final destination to add fish too, that way you have all the time in the world to re-setup the system being moved.
