I got both tanks plumbed together into my tiny sump and waited a couple days to make sure everything looks good. It does, so today I moved a lot of my coral over. I took out everything that wasn't on a huge rock. I still have an encrusing monti and a table acro in the 55, along with a small clam that has attached to his rock that I don't have room for. I also got out my RBTA and percs, but I'm hoping to borrow a fish trap for the rest. I can't believe how small my RBTA is when stressed out ...
