After a year of this I've decided that I like it better than fresh water. I'm moving my tank into a slightly larger size. It is a 30 gallon cube with 15 watts of 50/50. I will need to put in new mud and sand. I don't have my new lights yet. Is it ok to start it up with the mud and sand and maybe some rocks and let it sit with limited light for about a month? I will leave room for additional rocks and water etc? I'm trying to make the transfer as smooth as possible to keep some of the "age" of the little tank. I will move my little 300 AC refugium when I get the rest moved over. What do you all think?
