Our Desert Storm Ecoscape rock is not only an artistic choice for the home aquarium, but also a safe choice for both fish and plants. Desert Storm has many of the same desirable properties as Dragon Stone but is more durable and is proven to provide less dust. Its texture is similar to lava rock, giving it great porosity for nitrifying bacteria, and also as a great base for growing moss. It is inert and will not alter pH or hardness. It comes in a variety of shapes and sizes handpicked by the Ecoscape team to give your aquarium a unique look.
