I currently have a 90 gallon corner DAS tank that has about 3-4 of sand, about 150lbs of Live rock and a lot of corals (mostly SPS and Zoas and few fish. I am switching to a 105 gallon tank that I am going to do sand less bottom, but limited on time to set it up. I have a plumbing issue that is causing me to tear it down and start with a new tank. My question is, can I setup my new tank and use all the water live rock ect.. and just add more already mixed saltwater and be ok? Or should I try and take like half the water out use it with already mixed saltwater, let it run a mini cycle and then do another big water change before moving live stock? My thoughts are moving over current water with a little extra new water is that it will already be cycled and would not be much different then people setting up a temp tank for a move. I really just don't want to lose much live stock during the switch. I only have about 2 weeks time frame or less depending on how bad the plumbing in the house gets.
