Do I need aquarium sand or gravel?

If you have already looked up aquarium sand online, you have probably also noticed that aquarium gravel is also an option. Even though these two items are similar, they are not the same. The main difference is that gravel is much larger than sand.

You may be wondering which one is better for your fish tank. In our opinion, aquarium sand is a much better choice; it is much easier to clean and safer for your little pets. If you buy aquarium gravel, there is always the risk of your fish swallowing the gravel; this can be extremely unhealthy. In conclusion, we recommend buying aquarium sand, but, if you wish, you can combine the two.

Is aquarium sand just for decoration?

In general, all aquarium sand for freshwater tanks is only for decoration and usually comes with a wide range of colors and materials to choose from. If you decide to add aquatic plants into your tank, you need to purchase a nutrient-rich soil. Sand is inert and will not help these plants grow.

If you do have plants, you should only put the sand where the plants will not be growing. It is important to note that aquarium sand also makes a home for beneficial bacteria that maintain the nitrogen cycle of the water.

What materials are aquarium sand made out of?

There is a variety of sand on the market; let’s talk about some of the most popular types. These types differ based on what kind of aquarium they can be applied in, their color, and the material they are made out of. We will expand on these different kinds of aquarium sand in the list below:

  • Quarts aquarium sand: This type is very classic and one of the most common types. It comes in white color and brings a lot of light to the aquarium. Quarts aquarium sand will also make your fish tank look cleaner and larger than it actually is. You can use it in any type of fish tank, and, since this sand is neutral, it will not change the chemical composition of the water. However, it is important to note that some experts say that the white color can confuse certain species of fish.
  • Coral aquarium sand: This sand is made out of crushed coral and gives the tank a natural touch. This type of sand is created specifically for saltwater fish tanks. Due to its structure and composition, good bacteria will grow quickly with this sand. These bacteria will help maintain a stable pH level and nitrogen cycle which will be very healthy for your fish.
  • Cristal aquarium sand: This type of sand will make your tank look original and different from the rest, especially if you have colorful fish. It is also chemical inactive. So, it will not change the chemical composition of the water. You can use this sand in freshwater or saltwater fish tanks.
  • Silica aquarium sand: You can use this sand in any type of fish tank. It is very soft and natural-looking. Before putting it into your tank, we recommend that you rinse it several times to remove all of the powder that it may contain.
  • Reef aquarium sand: This sand is one of the best options for a saltwater fish tank. It comes with important nutrients that will benefit the health of your fish. It is harvested in a natural environment and helps maintain the pH level, salinity, alkalinity, and more.

How do I choose the best aquarium sand for my fish tank?

Neutral (chemically inactive) aquatic sand can be used in any type of fish tank, but you should keep in mind that certain types of sand are better for saltwater tanks. Experts recommend that the sand should be as fine as possible and duller in color. However, it is your choice how you want to decorate your tank. Every aquarium is different.

We recommend that you avoid any sand that is made out of limestone. This type of sand has a high percentage of calcium carbonate. Instead, you should choose a neutral or silica aquarium sand. Once you add the sand of your choice into your tank, you should always observe your fish’s behavior.

How do I clean my aquatic sand?

Although you probably already know this as a fish owner, cleaning an aquarium requires both time and patience. Your fish and plants deserve the best ecosystem possible and it is important to follow the correct steps when cleaning their sand. First of all, especially when it comes to silica sand, you should rinse it various times before putting it into the aquarium.

You can clean the sand inside the tank. You need to clean it regularly as fish food and other waste can build up at the bottom of the tank; let’s say, every time you change the water of your aquarium. You will need an aquarium siphon. This item will vacuum out the filth.

Why can’t I take the sand out and rinse it?

After a while, aquarium sand begins to develop lots of beneficial bacteria. If you take the sand out of the fish tank and rinse it, you will be removing these bacteria.

Shopping Criteria

As you have seen throughout this article, there are a lot of details that you probably did not know before when it comes to aquarium sand. You may now be more confident about your purchase. However, before you make your final choice, there are a few shopping criteria that you need to keep in mind that will help you make the best purchase possible:

Type of Aquarium

There are many different types of aquarium sand and, while some can be used with any type of fish tank, others are made specifically for saltwater. Saltwater aquatic sand is a bit more expensive than normal sand because it is usually natural.

If you are setting up a saltwater tank and you want it to look as natural as possible; you need to choose aquatic sand that is meant for this type of fish tank. On the other hand, if you are setting up a freshwater tank, you have a lot more products to choose from.

Cleaning

It is very easy to clean aquarium sand inside the tank. When you buy it, make sure to read the product’s description. As we mentioned before, if you purchase silica aquarium sand, you need to rinse the sand several times before putting it into the fish tank. Rinse it until the water runs clear. Patience is key.

Advice from Other Users

If you have a friend or family member with an amazing fish tank, ask what type of sand they use and they will give you some great advice. It is also always a good idea to go over the different ratings and reviews from other online users.

Summary

To sum up this article, we want to take this time to remind you that each aquarium is an ecosystem, not just a decoration. Your aquatic plants and fish deserve the best. That is why it is so important to choose high-quality aquatic sand that is made for the type of tank you have. Taking care of a fish tank takes time and dedication.
