Rock & Sand
Live rock is the most popular material used for natural biological filtration in saltwater aquariums. Aquarium live rock comes in two forms: wet and dry.
Wet rock is going to be a bit more expensive with its expedited air shipping. However air live rock will come loaded with natural bacteria, coralline algae, and other organisms. We have even found anemones and corals on air rock before.
Dry rock is going to be less expensive and easier to aquascape with. Dry rock we stock in our warehouse, and does not come with any living material on the surface. With proper curing, and a bit of time, dry rock can be covered in coralline algae and bacteria for an extremely natural looking aquascape.
Live sand helps create an aesthetically pleasing reef tank but also provides necessary live bacteria to help quickly cycle your tank. Choose the live reef sand that not only catches your eye but also coordinates with your aquarium's high or low flow and benefits your tank's inhabitants.
