Benefits of Using Sand in the Aquarium

If you are using sand in your aquarium for the first time, you may have some reservations. Many people feel a bit uncomfortable when using it for the first time.

To put your mind at ease, here are some of the benefits of using sand in an aquarium.

1. Some types of fish come from sandy environments. Therefore, a sand substrate in the aquarium will help them feel at home. For some species, sand may not be mandatory, but for others, it can help them feel calm and adapt easily to the environment.

2. Depending on the species you grow, some of them can only breed in sandy environments. In such a case, there is no other option than to ensure that the aquarium is filled with the correct amount of sand.

3. Some species require sand to aid in digestion. There is nothing wrong with creating conditions in the aquarium that help fish digest their food better.

4. The use of sand can also be an ideal option for different types of aquatic plants. You can get some types of sand that are embedded with nutrients important for aquatic plant growth.

5. The small size of the sand grains compared to gravel is important because it provides more surface area for beneficial bacteria to colonize. Having more of these bacteria is important to keep the aquarium healthy and clean.


How To Use Sand In Your Freshwater Aquarium

The recommended minimum depth of sand you would like to have in your aquarium is one inch. If you want to keep plants alive, your substrate should be two to three inches deep to allow the plants to take root. A handy online calculator can be found here.

You must clean the sand before using it in your tank. Fill a bucket halfway with sand, then add water until almost full.

Use your hand to sift the sand and then drain the water from the sand. Repeat this process until the water is clear.

After adding the sand to your tank, place a sign on the sand. Pour water into the bowl. This prevents the water from disturbing the sand, pushing debris into the water column as you fill the tank.

Cleaning sand can be done the same way as gravel, with just a few differences.

Here’s a video showing how to use a vacuum in sand.


Types of Sand for Aquarium

play sand

In most cases, playing in the sand would eventually be the default option. Play sand is non-toxic, which is important for keeping your aquarium clean. Don’t make the mistake of choosing one with a high clay content.

This makes cleaning the aquarium a nightmare. That said, you can find many reputable companies that offer high-quality play sand that you can safely and effectively use in your aquarium.

Swimming pool sand

This is the other type you could use, especially if you don’t mind the white color of the pool sand. For most people, the sand in the pool often seems superior to the sand for playing. The reason is that the particles of this type of sand are more uniform, creating a better surface.

The other reason is that the sand in the pool is free of contaminants, so you don’t have to worry about your fish. The downside to this type of sand is that the bright white color can be dazzling if you have a highly lit tank.

Special sand

With the growth of the aquarium industry, you can be sure that new and innovative accessories will appear in the market. That’s how we ended up at the special arenas. They are made to be good for the aquarium in every way, so you may find them expensive.

One of the best properties of this type of sand is its neutral PH. This is important to ensure that the sand does not affect the pH level of the aquarium water.


Which is Better – Aquarium Sand or Gravel?

These two are important substrates that you can find in any aquarium, but users often have a hard time choosing between the two. Starting with gravel, you will find that it is best for freshwater aquariums. The advantage is that the water can easily flow through it compared to sand. This helps prevent the build-up of harmful bacteria and amoebae in the substrate. If it builds up, you can get sick fish and a buildup of other contaminants.

Gravel is heavy and therefore does not enter the aquarium filters. If this were not the case, the filters would easily become clogged and function less efficiently. The gravel also comes in a variety of colors so you can customize the tank and replenish the fish any way you want.

Sand substrate, on the other hand, may not allow water to flow easily like gravel, but it can be great for fish species that like to dig in sand. This type of fish can be ideal for filtering the substrate. Sand also has many other advantages over gravel, such as making tanks look natural and mimicking riverbeds.

Because the sand is very compact, it does not need to be changed often. Old food and plants easily stay in the sand and rot instead of getting into the sand.

Between the two, sand can have more uses compared to gravel. This is why you will find more and more people interested in switching to using sand in their aquariums.


Aquarium Sand – Q&A

1. What is the sand in the aquarium made of?

Depending on the type of sand, the materials may vary. You can have some made of hard rock, while others are a combination of hard rock and other materials to make aquarium sand.

2. How much aquarium sand per gallon?

There are several methods you can use for the approximation, but generally you will need about 1 pound of sand per gallon. This means that if you have a 10-gallon tank, you’ll need 10 pounds of dry sand. This is often considered sufficient to achieve impressive results.

3. How do you add sand to an established aquarium?

When setting up the aquarium for the first time, start by collecting the sand with a plastic cup and add it to the bottom of the aquarium. Be careful not to pour large amounts into one area as this can create stresses that can cause the glass to break.

For a tank already set up, you’ll need to scoop the sand into a plastic cup and then dip the cup into the water and pour it to the bottom. Throwing the sand on the water will make it cloudier and make it look dirtier.

4. How long does it take for the sand to settle in the aquarium?

Setup can take a few hours to a few days. This depends on the size of the aquarium and how you put sand in the water. If you just threw it away, it can take up to 3 days to fully cure.

5. How to clean the sand in the aquarium?

Start by pouring the sand into a bucket and fill it with water. What follows is to mix the sand and water in the bucket in a circular motion. This is important to remove the sand heaps from the bottom and allow the water to reach well. Wait about 30 seconds for it to settle. This is where good sand will sink quickly and leave you with floating bits of dirt.

Slowly add the water so that you have clean sand at the bottom. Repeat the process about 5 times or until you are happy with the resulting sand after washing. You should now have clean sand ready to go back to the aquarium.



There you go. With some of the best products reviewed, you don’t have to get confused about the type of product to choose today. You can have the best aquarium sand for plants or any kind by looking at the reviews above.

With the many benefits that sand has to offer, you can always find a way to add sand to your aquarium to serve your purpose. With many benefits to be gained rather than risks, you will easily understand why sand is best for your aquarium.

How Much Sand Do You Need for a Reef Tank?

The depth of your sand bed is an important consideration when setting up a reef tank and you don’t want to get more or less sand than you need. So how do you find out what the right amount is?

How to calculate the amount of sand per gallon?

To know exactly how much sand you need in your tank, you need to know the depth of the sand bed you want to create and the dimensions of the tank bottom.

But there is an easier way to get an approximation by just using the tank volume. The volume of your tank in gallons is approximately equal to the amount of sand in pounds it takes to make a 1 inch bed. So if you have a 10-gallon tank, 10 pounds of dry sand is enough for an inch bed.

shallow vs. Deep sand beds

There is much debate in the aquarist community as to whether a shallow bed, between ¼” and 2″, or a deep bed, between 3 ½” and 6″ or more, is better.

Shallow sand beds remain oxygenated at all times, so to avoid nitrogen buildup that could alter the chemistry of the water in your tank, you should siphon the bed about once a month.

On the other hand, deep beds do not have oxygen at the bottom of the bed, which allows bacteria to facilitate denitrification so that the nitrogen balance in the tank is self-correcting.

Therefore, deep beds require little or no maintenance and can even be damaged by intensive cleaning.

In general, avoid sand beds between 2†and 3 ½â€; Beds at this depth will allow toxic chemicals like hydrogen sulfide to build up and back up into the tank water, which can be quite harmful to your aquarium.


How to Keep Your Sand Clean in a Reef Tank?

Reef sand is very different from most other substrates. You really don’t have to change it often. Instead, it’s ideal to add a few animals to your reef tank to turn over the live sand. These creatures are affectionately called janitors, keepers, or cleaners. Some good options are hermit crabs, shrimp, gobies, or jaw fish.

Be sure to research these creatures before putting them in your tank, as they can’t all live together in peace. If you get the right mix of janitors, you won’t have to clean the sand thoroughly.

That said, it’s still important to maintain a clean surface. Use an aquarium vacuum cleaner or siphon to clean up any food or debris. Make sure you also get everything that is hidden between stones or plants.



A reef tank requires a perfectly balanced tank that can be difficult to get to. That’s why it’s important to use the right sand as a substrate when building your tank environment. We looked at several great options, all natural sand collected from the ocean floor with its colonies of beneficial bacteria intact.

Using the best reef sand will not only make your aquarium look beautiful, it will also be less work for you. By supplying the beneficial bacteria that water needs, sand helps keep the water clean and pH balanced without the use of chemicals. Add some janitors to the tank and they will do the job of removing the sand for you. All you need to do is use an aquarium vacuum or siphon to remove debris from the sand surface if necessary. That is! Without changing or washing the substrate, without rotating water.

Our pick for the best sand for reef tanks is Carib Sea Arag-Alive Pink Fiji Sand. It looks great and it also has all the elements you need to keep your tank water clean, pH balanced and free of contaminants. This substrate never needs to be replaced and no additional chemicals need to be added to the water. It will continue to help your aquarium to thrive throughout life.
