54 gallon perc tank

Live mostly refers to the bacteria from your LR colonizing the sand, turning it into LS. Ideally, if you can get some old LS from an established tank that has pods, mysis shrimp & other creatures living in it already, these will help populate the tank & feed your fish. Aragonite sand is usually used because it keeps your calcium & pH levels higher, which makes life easier for you & will especially help if/when you decide to add corals. The vast majority of sw fish are coming into the LFS within a week or so of being captured from the tropical seas & so many will be a bit finicky about eating flake or frzn foods, so it is useful to have some live food (like pods & mysis) running around in the tank.
