Depends what you want to put in there. Personally I like the look of sand than just bare bottom. If you go with no sand you can't have certain animals like nassarius snails, tube anemones, or a wrasse. Without sand though, you can clean the detritus more easily and keep an overall cleaner system. If you're getting an SPS
dominant tank it would be easier to keep the water very clean without sand. It's preference and each has its pros and cons. If you go with sand, 1-3 inches is a good amount.
