I'm seriously considering upgrading my 29g to a 60g cube and use the 29g as its refugium. Right now, because it's fallow, the only things in it is the CUC, coral, a sponge and 2 anemones. I want the 60 to go in the same spot as the 29g. How in the world do I do that without killing everyone? There has to be a way. This isn't likely going to happen until at least March or April, but I'm trying to plan it out and this is a major stumbling block.
