OK all the plumbing is in and my new sump is in place in the basement. My display 120 gal flat backed hex is in the upstairs living area. Soooo here is my question. Do I place all my cleaned sand in the main tank first and then add the water or water and then the sand. Either way looks to me like it is apt to cause quite a bit of silot in the water. Any advice is appreciated. I've never done this on this scale before.
