There are so many things that you have to take into account when designing your aquarium and one of which is aquarium rock. We suggest that you make it a point to choose, prepare and position all the aquarium rocks you will use in a proper and appropriate manner so that you can transform the clinical setup environment of your aquarium into the actual natural habitat for fish and plant.
One very important thing that we want you to know regarding aquarium rocks is the fact that not all of them are identical in terms of composition and not all of them are suitable for all kinds of aquarium since there are those that will only work best for certain types of aquarium. And since not all of them will work well with your aquarium, you have to make sure that you do some test on it to see if they are safe and if they can be placed in your aquarium. What we are trying to say here is that the type of aquarium rocks that you can use safely for your aquarium is dependent on the type of fish as well as plant species you will be placed there.
If you are going to ask us what type of aquarium rocks best fit for a freshwater aquarium, we highly recommend inert rocks. When we say inert rocks, we are referring to the types of rocks that include the following: basalt, obsidian, coal, quartz, sandstone, and shale as well. As the name suggests, inert rocks the kind of rocks that do not affect the chemistry of the water. That is why inert rocks are the best choice when it comes to freshwater aquariums.
On the contrary of it, if you are preparing to have a hard water aquarium or a brackish aquarium with the intention of raising the hardness or pH level of the water without using any chemical treatment, the best possible option you have for this are Calcerous rocks. One thing about Calcerous rocks that you should be aware of is the fact that they alter the pH level of the water and raise the hardness of it as well. These types of rocks are the direct opposite of inert rocks which are commonly utilized for freshwater aquariums. Several varieties of Calcerous rocks come in the form of limestone, marble as well as chalk.
That is why, as much as possible, you have to make sure you conduct your own research because this will greatly help you in determine which among these two categories of aquarium rocks offer the types of rocks you should use for your aquarium.
