Transporting Corals

I wouldnt using any of your old tank water, there is nothing to be gained from it. I also would bag your coral and fish separately. Coral may sting each other

 

I would think it would be better to transfer the old water since these are NOT going into an established and already running tank in his house. (assuming I read that right in the initial post) The aged water would keep more of the bacteria to help prevent/reduce a nitrogen spike.  If they are going into a already established tank I would say don't bother transporting the old water.

 

I would separate the fish together and coral as much as possible for the move also, like Mike said the corals could sting each other if allowed to touch.

 

My understanding is the water really holds nothing that is going to help establish a tank. I have done 100% water changes with no ill effects before but I am also using established sand and rock which is where all the beneficial stuff is. Now if you are going to be using rock and sand that is going to have a lot of die off , which in this case does not seem to be the case, I don't feel any amount of tank water would help to prevent a cycle.

 

Is the pH of the new water close to that of the water in the office tank?  If there is a big difference, that would make a case for carrying over some of the office tank water.

 

Not sure if this is an issue or not, but if you disturb your sandbed for the the move, can that release enough phosphates and other unwanted things into your water column? Maybe leaving the sand in the tank for the move is an option? Or replacing it with fresh sand...I don't know, I have never done it, just thinking out loud here

 

This is true but I think it is usually a bigger concern if you have a deep sand bed.
