How to Add Rocks to an Aquarium

Rocks can add a new dimension of beauty to a home aquarium, giving them the look of a natural habitat. Rocks of different shapes, sizes and colors can be purchased from pet stores. The rocks will vary in price depending on their scarcity and aesthetics. Some are rough, some smooth, some affect the water's pH and some glow under the right lighting conditions. Regardless of the type, adding rocks to an aquarium requires more effort than merely tossing them into the water.
