I am new to this hobby and I need help on deciding on the type of sand to use and the color. As of now I am adding live rock into a 55 gallon tank until I get my stand built for my 72 gallon bow tank. When the stand is completed I will transfer my water and rocks into the new tank then I'll add sand. I was wanting to have a reef tank with fish in it but couldn't decide on if I would like to have a solid color sand or a mixed black/white sand. Which would be best to use?
