Question about tank change

[Pizzapro83]

I have a 120 gallon tank and a 36x24x12 frag tank all plumbed together. I am braking them down to redo my tank. I have an extreme blue clove polyp problem. I went out and bought a new 75 gallon tank. I am going to be moving all my corals and a few fish to this tank. I will be cooking my live rock with all the cloves on them to kill them. I will then cure them and setup my 120 and recycle it. My question is when I break down the 120 and move everything to the 75 should I use my tank water and new live sand. They will onlt be in there till I setup my 120 and get it cycled. I was thinking to use 75 gallons of tank water and filling the sump with new water so it would be just like a water change. What do you guys think? Any suggestion would be appreciated. Thanks Frank

I would use the old water and a cup of the old sand as well.

So you think it would be ok to do that way. Just add a cup of old sand.

You will be moving the rock without the cloves as well right? If so, you should be fine.

Most rocks are covered in polyps. So it would be just a couple of pieces. Will it be ok if I put them in sump?

Sump is fine.
