How To Choose The Most Suitable Aquarium Rocks

Having an aquarium with beautiful fishes is a decoration to your office or house. In addition to being a decoration, it serves as a therapeutic tool which brightens up the mood.

There are different kinds of aquariums that you can choose from, you should consider them before buying yours. When selecting aquarium rocks, know the safe types for use in your aquarium.

Igneous rocks only give decoration, and no other benefits. There are basic, intermediate and acidic volcanic rocks. Several of these rocks are suitable to be used in the aquarium since they are non-porous. On the other hand, weathered igneous rocks soak up water because they are porous therefore becoming spongy and weathered.

Layers of deposited silts and sand forms sedimentary rocks. Depending on the material that binds the deposit together such as lime, mud, and quartz, their composition varies. Sedimentary rocks are of two types which is the limestones and the sandstones.

Both are decorative, but you should choose quartz-based non-porous sandstones for freshwater aquarium. Limestones however, are suitable for marine aquarium.

Heat and pressure applied to igneous and sedimentary rocks causes the formation of metamorphic rocks. Slate, marble and dolomite are the common metamorphic rocks. Marble is suitable for a high PH aquarium. Slate is used as a surface for spawning whereas dolomite is suitable for alkaline environment.

Choosing the ideal type of plants, rocks, and ornaments for some species of fish is a challenge especially for first-timers. You are advised to do research, consult professionals and read articles.
By obtaining your own rocks, you will save on cost. Health of your aquarium will be endangered if you choose the wrong kind of rock. When you select a rock randomly from your garden for your aquarium; there is a high possibility that the water parameters will be altered.

Some rocks can alter PH levels and water hardness.
Growth of bacteria is another factor that you need to consider. Some rocks harbor bacteria that may thrive easily in your aquarium. Avoiding rocks picked from polluted areas should be your rule. Avoid brittle rocks which can crumble inside your aquarium because of erosion and choose solid ones.

Do not get your aquarium rocks near water banks thinking that the rocks are used to water. Rocks from bonds and streams might carry harmful bacteria, and other micro-organisms which are helpless outside but are harmful inside the aquarium. Using rocks found close to water bodies almost always causes damage.

Rocks that you introduce in the aquarium should not contain any metal. The health of the fish will be compromised since most metals develop rust inside water. You are advised to avoid any metallic rock to be introduced in your aquarium at all costs.
