I currently have a 75 gal display and 29 gal sump in place that has been running for a year. Due to some recent luck, I will be setting up a 125 with 40 gal sump. I have heard mixed things about transferring sand beds. My 75 gal display currently has about 2-2.5 inches of sand and my sump has about 6 inches of sand. Some have told me that it will be fine to move the sand beds and others have said to start with fresh sand. Has anyone heard of any danger using the same sand that will be disturbed? I have a beautiful mixed reef that with lots of SPS that I do not want to harm. Also, what about completely dry rock that has never been cured? Will this need to be cured, or since there is no dying bacteria on it to cure, will it be fine to drop in? Thanks for any help offered.
