I am setting up a 75 gal and have a 30 long that I was thinking about using as a sump or refugium (sp?) Do I need to have a Deep Sand Bed in the 75 if I have it in the sump? I was planning on putting about 4 1/2 inches of sand in the 75 and then pressing live rock into it. I figure that this will increase the depth of the sand to 5"+ Or can I just put 2 or 3" of sand in the main tank and have a 5" bed in the Sump? What would you recommend?
