Hello everyone, new to the forum. In a couple of weeks I'm going to be buying a 180 gallon completely setup and running system from a guy online. He lives about 3 hours from me. I have a good plan in motion to get everything moved and hopefully keep everything alive. My only concern is when I'm setting up the tank at my house and I add the sand, what should I do with the fish and corals while the sand is settling because I know it can take a while. Thanks in advance for any tips or information!
