You can make the next rock on top of the first one by making a layer of crushed coral between each rock. This saves space, and that is important if you live in the city. Each layer that you add can be the next letter in the name. Be careful if you pick the box up, because it can be very heavy.
Please let the rocks cure an extra day because there is extra stress on them when you dig them up. Start removing the rocks by gently shaking the box. This loosens them from the crushed coral.
