The Benefit of Having Substrate in Aquarium
Let’s first think one thing, if you want to build a beautiful garden what is the most important thing you need? Good soil, right? So when your garden needs soil, if you want a healthy planted tank then you have to give it something where the plants can grow and therefore the importance of using substrate is immense.
Now the benefit of having substrate in aquarium is not only limited for the plants, there some other advantages for which you should use a good substrate in your tank. Some of the benefits are discussed below.
- When you are using a substrate it works as a medium to create different beneficial bacteria. Now these helpful bacteria are really important to be present in the water to maintain the nitrogen cycle. In natural water bodies, like ponds or rivers there is presence of different types of bacteria and these converts the waste into foods. Different types of substrates contain these bacteria which can do this organics breakdown in your aquarium. Therefore, using substrate means creating a more natural environment for your aquarium.
- Next, benefit that you will get from using substrate is it will help you to keep the water clean. No matter how well filtration system you are using, the water is going to get dirty. However, if you are using a high quality substrate then it will keep the waste at the bottom layer of your tank and the water will remain clean. There won’t be no floating of dirt in the water and the water will be less polluted.
- Adding substrate in your aquarium creates a more familiar environment for your aquatic animals. In rivers, oceans or even in ponds there are mud, sand, pebbles, rocks and so many other natural materials. Obviously these things are missing in your aquarium but when you use a substrate it creates almost the same living environment for the fishes. Even some fishes like shrimps need to some places where they can hide or for snails where they can bury themselves. Your aquatic animals can also sit at the bottom rather than floating in the water all the time. So for all of these reasons you should use substrate.
- Last but not the least, the best benefit of using substrate is that it is a great source of different nutrients. There are different kinds of substrates available in the market. Different substrates contain different elements and thus different qualities. Using a substrate according to your need you can provide essential elements which are required for the plants and also for the fishes. For example, potassium, magnesium, iron, sulfur etc. keeping pH level at an optimum level is also very important and you can do that by adding special type of substrate. Moreover, if you need to soften the water even then you can use substrate.
So mainly for growing plants in your tank you must use substrate which works as a soil for the plants. But you can see there are some other great benefits of using it and therefore you should go for one which is suitable for your need.
Different Types of Substrate You Can Buy
There are many varieties when you are going to buy substrate for your tank. There is a variety of elements, color, texture, quantity, and material. Before you buy one you need to understand the different types of substrates which you can purchase. Below we have narrowed down some of the popular types of substrates for you.
Avery common substrate used by people for their aquarium is sand, especially if someone is a beginner. Now the normal sand and aquarium sand is a little bit different, therefore you have to buy those sands which are made especially for use in the aquarium. Using sand works very good if you own fishes that like to dig into the sand and bury them.
One major problem of using sand is that for the very small particles it can easily enter to the filters and therefore cause problems.
One of the most popular substrates for an aquarium is gravel. The reason why it is so popular is for its simplicity. It is easy to use and can work for different types of aquatic animals and for different types of tanks.
Now just like the sand, aquarium gravel and normal gravel is different. The gravel which is used in an aquarium has smoother edges. For this reason, these don’t cause any harm to the fishes. Moreover, these come in different colors and size that gives you more options to decorate your tank.
This type of substrate looks almost like soil because of its color, either this is grey or black. This soil substrate works as well as sand or gravel. Compared to sand, soil substrate contains more nutrients to your tank and therefore it is the best substrate for a planted tank. It provides multiple nutrients which are required to have a healthy planted tank.
This soil-like substrate has many varieties; you have to find the perfect one for you. In our review section, we have mentioned about some soil substrates.
If you want to grow plants in your tank and need something that gives the root development then you must go for a complete substrate. Some of the examples of the complete substrate are CaribSea Eco-Complete Substrate or the ADA Aqausoil Complete Substrate.
Complete substrates will provide the necessary nutrients to your aquarium and at the same time, it maintains the nitrogen cycle. One very important thing to remember, while using any kind of complete substrate is that you have to add them before when there is no fish. After adding it, check the pH level and then add your aquatic creatures.
Lastly, one of the most commonly used substrates in many tanks is marbles. Marbles are spherical and flat and these come in many different colors. Marbles have been used mainly to decorate the aquarium.
Obviously, marbles don’t add any nutritional value to your tank, but many fishes love to sit on them. Because of the size, there is a gap created between the marbles and the foods can get trapped in this gap. Where this is a problem, on the other side some aquatic creatures love this gap for breeding purpose. Even these gaps keep the eggs safe from other fishes.
So these were some of the basic and most common substrates that you can buy for your aquarium. Make sure you have enough knowledge about each of them before you make a purchase.
How to Setup Substrate for Planted Aquariums

Moreover, you will get to know how the substrate affects the water. Even if you are using a completely natural soil, you have to give this time.

Add them according to your wish and you want to decorate them. Different types of plants will give your aquarium a more natural looking vibe and it will increase the beauty of your tank.
