I’m going to be upgrading my 60g sps tank to a mariner m130. If I transfer my water,live rock, corals, fish and invertebrates but no substrate what problems can I expect to have? The substrate in my 60 is too fine so I don’t want to use it. I thought of going no substrate at all in this tank. Or I thought TBS live sand or special grade reef sand if I did go with a substrate. How can I do this transfer without killing my sps. I won’t be able to have both tank up and running to cycle the 130 for a long period. Any advice?
