|This lesson will show you a simple way to make Aragocrete™ sculptures for reefs with out a sand bed. These pieces will stand up on an empty bottom or a light grid floor. This rock is great for making a space near the lights for corals that need more light.
Tall thin rocks allow you to use the full reef to grow corals, because the thin shape does not cast a shadow over much of the rest of the reef. You can move the sculptures around, so you can view all of the corals.
