What To Look For When Choosing Aquarium Rocks

Having an aquarium with beautiful fishes is a decoration to your office or house. Besides brightening the room, it is a therapeutic tool that lightens up your mood.

Before buying your aquarium, you should know the variety of choices that you can select from. When you are choosing aquarium rocks, you have to know the kinds that are safe to be used in an aquarium.

Igneous rocks are decorative but don’t have other advantages. Igneous rocks exist as basic, acidic and intermediate. Several of these rocks are suitable to be used in the aquarium since they are non-porous. However, weathered igneous rocks soak up water since they are porous therefore they become weathered and spongy.

Formation of sedimentary rocks is caused by layers of deposited sands and silts. Material which binds the deposit like mud, lime and quartz causes the variation of the structure. Two types of sedimentary rocks exist, that is the limestones and the sandstones.

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

Metamorphic rocks are formed from the sedimentary and igneous rocks, by temperature and pressure. Slate, marble and dolomite are the common metamorphic rocks. For aquarium that has high PH, marble is an ideal rock. Dolomite is suitable for alkaline environment while slate is suitable for use as flat surface for spawning.

When purchasing an aquarium for the first time, choosing the correct kind of plants, ornaments and rocks for a specific species of fish is difficult. You are advised to do research, consult professionals and read articles.
By obtaining your own rocks, you will save on cost. Choosing the wrong type of rock risks the health of the aquarium. If you randomly pick a rock from your backyard, there is a high likelihood that the water parameters of your aquarium will be affected.

Some rocks can alter PH levels and water hardness.
You should watch out for the growth of bacteria. Some rocks can host bacteria which can grow in your aquarium. The best way is never to collect rocks from polluted areas. Always pick solid rocks for your aquarium that doesn’t crumble due to decay rather than brittle ones.

Do not get your aquarium rocks near water banks thinking that the rocks are used to water. Rocks in ponds and streams may be carrying dangerous bacteria and micro-organisms that are helpless from outside but are very harmful in the aquarium. There is a high likelihood that an aquarium that uses rocks from water bodies will not be successful.

You should ascertain that you use rocks in your aquarium that does not contain a 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.
