Setting up a 10-gallon tank is a fun and rewarding experience, but getting the details right is important.
One of the most important aspects of any aquarium is the substrate or bedding material.
In this article, I’ll discuss how much gravel for 10-gallon tanks is required and why it’s so important. This info will help you further if you want to set up a larger aquarium than a 10-gallon tank.
I’ll also explore some other substrate options you may want to consider. Let’s get started!
What Are The Benefits of Using Gravel In Your Aquarium?
Gravel is one of the most popular substrate options for various reasons.
First and foremost, gravel can help trap debris and contaminants, which helps look your tank clean and healthy. On the contrary, debris may float all around your aquarium water in a bare bottom tank.
Gravel adds a beautiful visual element to your tank and can be used to create interesting displays. The reflection of the light in gravel, especially if it’s colorful like the Glofish Aquarium Gravel, is so fascinating.
It also provides a home for beneficial bacteria, which play a vital role in aquarium maintenance. The large surface area of gravel helps bacteria colonies to develop in your aquarium. Bacteria will grow all over the surface, working as biological filtration and helping avoid new tank syndrome.
Gravel is a great way to give your fish a sense of home. It will help them feel safe and welcome in their new environment! But, of course, this also stands for other substrates. It mimics the natural habitat condition, like the bottom of a river, lake, or ocean.
Finally, if you want to add some aquarium plants, gravel working as a substrate helps anchor them. Read more on how to plant aquarium plants in gravel.
While using gravel, one aspect you should look at is that you need to clean those entrapped dirt particles using a gravel vacuum weekly or bi-weekly. Otherwise, it can lead to other problems, such as a smelly fish tank.
Factors To Consider In Deciding Type & Quantity of Gravel
The type and amount of gravel you need for your 10-gallon tank may vary depending on a few factors.
Type of fish:
The fish type you have determines how much and the type of gravel you need. For example, some fish have a burrowing tendency, and they prefer to do that on a substrate that is not too coarse.
Bottom-feeder fish like Corydoras, Eels, and Loaches are some examples of fish that like to burrow in the gravel. If you have such fish, you need a minimum of two inches (five centimeters) of gravel.
But if your fish don’t have any burrowing tendencies, a regular amount is good enough.
Plant Type:
If you plan to keep live plants in your tank, you’ll need to consider their type to determine the gravel amount. For example, some aquarium plants, like floating plants, can absorb nutrients from the water column. In addition, they don’t need to be anchored in a substrate.
Alternatively, those having long roots need a deep layer of substrate (gravel) depth to hold them up and get nutrition. Although gravel doesn’t contain any nutrients, a way to ensure nutrients for the plant is to use root tabs.
Aquarium Size & Shape:
The size of your aquarium also determines how much gravel you require. For example, 15 pounds of gravel is enough to reach 1.5 inches in height from the bottom in a standard rectangular tank.
However, suppose the tank size is taller or cylindrical in the shape of the same capacity. In that case, 15-pound gravel will create more height in the aquarium.
How Much Gravel For 10 Gallon Tank?
The calculation for the amount of gravel you need for a 10-gallon tank is quite simple.
The height of the gravel covering should be 1-4 inches from the tank bottom. Some aquarists also follow the thumb rule of 1.5 pounds of gravel per gallon of water. Therefore, if you use 10-15 pounds of gravel for a 10-gallon tank, it will spread out at the bottom 1-1.5 inches from the base.
However, the shape and dimension of the aquarium can alter the amount a little bit. The best idea is to cover at least 1-1.5 inches with gravel for a simple freshwater tank.
But if you want to add plants and you would like to add fish that like to burrow in the substrate, you should increase the height to 2-4 inches. Around 25 to 40 pounds of gravel will suffice to reach that height.
How To Prepare The Gravel Before Using it In The Aquarium?
Washing the gravel clean before putting it in the aquarium is crucial. Dust and other imperfections present can cloud the aquarium water and make your aquarium fish sick.
There are several ways you can follow in cleaning the gravel. One way is to use a sieve and pour water over the gravel in the sieve while gently shaking it. Whatever method you follow, make sure the gravel is clean and free of dirt.
What Are Some Alternatives To Gravel?
While gravel is the most popular substrate option, it’s not the only one. Here are a few other options to consider:
- Sand: Sand is another popular choice, and it has some advantages. It can create a more naturalistic look in your tank. Sand is soft and suitable for bottom-feeder burrowing fish. However, sand can be challenging to clean. It can clog the filter and lead to toxicity if not maintained properly.
- Glass marbles: Glass marbles are a popular choice for small tanks, as they’re easy to clean and add a pop of color. However, they don’t offer the same filtration benefits as gravel.
- Aqua Soil: Aqua soil is rich in nutrients and helps to support plant growth. However, it’s not the best choice for fish that like to burrow. Moreover, it is challenging to maintain and requires more attention in the first 3-4 weeks. You need to replace the water during the initial days to clear out the excess ammonia.

- Crushed Coral: Crushed coral is a good choice for aquariums with fish that like high pH levels. Since only certain types of African fish & aquatic plants can survive in this environment, your options are limited with crushed coral.
Besides the option mentioned above, a combination of dirt, pebbles, and small rocks is also used among fishkeepers as a substrate! However, gravel is probably the most widely used substrate in fishkeeping.
Ultimately, the best substrate option is the one that best suits your needs and preferences. However, no matter what substrate you choose, make sure you do your research to ensure it’s safe for your fish and compatible with your setup.
How Often Should You Change the Gravel?
If you buy high-quality gravel and clean using a gravel vacuum, you don’t need to change the gravel often. However, gravel may lose some of its luster over time; you may need to change some of them. If you want to last it longer, make sure you clean the gravel regularly.
How Often Should You Clean the Gravel?
You should clean the gravel weekly or bi-weekly based on the waste accumulation. Bi-weekly cleaning is sufficient if you have a lightly stocked aquarium. Other than that, weekly cleaning is recommended.
Fine gravel compacts over time and may form a zone of oxygen-deficient. In low-oxygen areas, anaerobic bacteria grow, converting wastes into harmful gases like hydrogen sulfide. Regular cleaning stirs the gravel bed and helps prevent that.
Wrapping Up
Gravel is an essential substrate for any aquarium. It helps to keep the tank clean and healthy while also providing a natural environment for the fish. There are many different types and sizes of gravel to choose from, so you can find the perfect one for your tank.
When selecting gravel, make sure it’s safe for your fish and compatible with your setup. Generally, you should change the gravel every few years or as needed.
You should also clean the gravel regularly to prevent the buildup of waste and toxins. Thanks for reading! I hope this article was helpful.
