Is there a danger that I will harm my aquatic pets by making the wrong choice? These are all questions that bother beginners in this hobby.
That is why we are here to help you. Well, keep reading and find out all about it.
Sand As An Aquarium Substrate
If you have saltwater, marine, reef, or brackish water aquarium, the sand is an ideal choice for a substrate. Although most hobbyists would probably reach for the gravel, it is not recommended for use because it does not do a very good job at creating a good marine or reef habitat. Sand, on the other hand, definitely does.
Since sand is what these habitats have in the wild, you should use it in your home aquarium as well. You are probably wondering, how much sand do I need for my aquarium? Stay with us and learn all about using sand as substrate as well as how much of it you are going to need.
Sand is the best choice because it has the ability to host various creatures and microorganisms which help to keep the tank alive. This is especially true when it comes to living bacteria. Namely, they have a unique role, reducing the level of ammonia and nitrite, but also many other substances that you certainly would not want to have in your tank.
As for the type, you can choose between inert and live sand. Inert sand is just sand, while on the other hand, live sand comes with bacteria and microorganisms and initially provides an aspect of biological filtration of things. There are several different factors to consider when determining the amount of sand you will use. Do you prefer fish or live plants to dominate the aquarium? What types of plants do you plan to plant? What types of fish do you plan to buy? In addition, think about decorations, filters, but also all the smaller and larger things that you will put in your tank.
How Much Sand Do I Need For My Aquarium?
As for the depth of aquarium sand, it can be divided into two different depths. So we are talking about those that are shallow (anywhere from 1 to 2 inches of sand), and on the other hand about those that are deep (anywhere from 4 to 6 inches of sand). The ones that are shallower are a lot easier to maintain but don’t let that stop you.
In addition to looking nice, planted tanks can be beneficial to your fish as well. You can play around and use a slanted substrate to create a more 3-dimensional aquascape. It will especially suit larger plants that have longer root systems. Accordingly, you can add 2 to 3 inches of sand, as this will be sufficient for most aquarium plant species.
As you might guess, overall plant health depends on the availability of nutrients in the aquarium. Therefore, try to include a nutrient layer underneath the layer of the substrate. Simply spread the nutrient layer on the bottom of your tank to a depth of about one inch and then cover that with two inches of sand.
A Guide To Making A Calculation
Determining the amount of sand is very easy using a calculator that you can find everywhere on the internet. Simply find a calculator, enter the required data, and in a few mouse clicks you will get the information you need. Furthermore, see the detailed procedure below.
For example, if you have an aquarium tank measuring 12.25 inches X 48.25 inches, you will be told that in order to form a 1-inch bed, you will need somewhere about 24 pounds of sand. All you have to do now is figure out how deep the bed you want it to be. Accordingly, if you want a bed 5 inches deep, you need to multiply that number (24) by 5. As a result, you will get that it takes about 120 pounds of sand to form the desired depth of substrate.
The amount of substrate you will use in your aquarium tank depends on several factors. Some of them are the size of your tank, as well as the types of fish and live plants you want to keep.
Generally speaking, you should have about 1.5 to 2 inches of sand in your aquarium. You can even use a little more if you have rooted plants. In addition, some plant species require an extra inch of a nutrient medium below the substrate itself. To calculate, simply take a pen and paper or use an online calculator.

Is Sand Good For Freshwater Aquarium?
Sand is not used so often in freshwater aquariums. Namely, most of the sand used in aquariums is silica-based and can contribute to brown algae. In addition, it is necessary to pay attention to the size of the grains. Truth be told, gravel is a much better choice for freshwater aquariums.
Is Sand Harmful To Fish?
Sand is not harmful to your fish, but you need to pay attention to some factors. “Silica-free” sand may contain calcium carbonate which is not so good for a freshwater tank.
Also, it would be advisable to avoid “dust-free” or “anti-dust” play sand. This type of sand is usually treated with various chemicals that can negatively affect the health of your underwater world.
Is Aquarium Sand Hard To Maintain?
Although one would think differently, aquarium sand is very easy to maintain.
Is Aquarium Sand Easy Clean?
Aquarium sand is very easy to clean primarily because tiny dirt particles cannot get between the grains. The only negative aspect is that the suction of sand takes much longer than the suction of gravel.
