I bought an established 55 gallon tank about two years ago. Rock is covered in purple, corals are thriving,everything good. I now have a 120 gallon,new sump,new led lights,ect. I want to transfer the rock and livestock from the old tank to the new one. I have new live sand I want to use and plan on using some of the old sand in the new refugium. My question is do I need to cycle the new tank even if i use my old rock? I do plan on getting more rock since the tank is bigger. Any questions or comments are greatly appreciated. Thank!
I have upgraded a few times through the past few years, always using fully cured live rock from established tanks and really don't go through the traditional cycling process of a new tank. Usually, I use new sand and see a few cups throughout the new sand with sand from my established tank. That, with the established live rock is usually enough to get things going.
Before I upgrade, I usually add extra foam blocks to my sump, then transfer them to the new sump along with the rock and new sand. Let that run for a few days, and then if tests look good, start moving some easier corals, then keep going from there. I've never lost a coral or fish (other than two that jumped on me).
I've done overnight upgrades as well when I don't have the room to keep the other tank running any longer. That's a little scarier/risky, but again, never lost a thing. Just keep a lot of Amquel and/or Prime and lots of extra water on hand in case of spikes.
