Gravel and sand are two of the most popular forms of substrate used in aquariums. And they have unique properties that you need to look into when you are still setting up your aquarium.

Benefits of Putting Sand Inside a Freshwater Aquarium

You might wonder: is there a need to put a substrate like sand inside an aquarium? There are several reasons why putting substrates like white sand inside an aquarium is beneficial. We have listed some of the benefits below:

  • For your plants and fish to thrive inside a freshwater aquarium, you need to give them a “home” close to their natural environment. Putting white sand helps you mimic their natural home. Certain fish species also tend to dig or hide, so they need sand to make them feel at home inside the freshwater aquarium.
  • Putting sand inside an aquarium helps you as well in optimizing the growth rate of your aquarium plants.
  • Some species of fish consume sand. Believe it or not, sand is helpful in their digestion. Sand is also the best substrate choice for certain species such as catfish as pebbles and rocks can injure them.
  • It is relatively easier to clean an aquarium with sand than one that has gravel in it. Also, sand does not easily collect wastes, so debris and dirt do not build up easily.
  • One of the greatest benefits, perhaps, is the ability of sands to help beneficial bacteria grow. Yes, bacteria can be beneficial, too! These are important in maintaining the health and overall wellbeing of your aquarium plants and fish.

Factors to Consider in Buying Sand for Your Freshwater Aquarium

One of the most common mistakes that newbie aquarium owners make is using the wrong kind of sand. Remember that not all sands can use for freshwater aquariums. There are certain factors you need to look into before spending your hard-earned money.

  • Type of Aquarium – The first thing you need to consider is the type of aquarium you have. Generally, finer sand is ideal for an aquarium with fish. If you have a planted aquarium, you need to go for nutrient-rich sand and add a layer of gravel to enable the plants to grow their roots.
  • Material – Most sands sold in the market are silica-based. You need to understand that silica can result in the growth of brown algae. Check if the grains of the sand you are considering have the necessary coating to prevent the excessive growth of brown algae.
  • Grain size – Even the sizes of sand grains differ. The actual grain size you need still depends on the types of fish or aquatic plants you have inside the aquarium. Aquariums with plants, for instance, may need sands with bigger grain sizes.
  • pH level – Check the pH level of your tank before buying white sand. Some types of sand tend to increase the pH level of the water. It is best to purchase those that will not alter the pH level of the water content.
  • Product quality – Of course, quality is one crucial factor you should not forget. The product should be safe and non-toxic. Best to check the reviews of other consumers to see if certain brands have adverse effects on their plants or fish.


Before deciding on which brand to use, it is best to look into your own needs first. More than the aesthetic value, white sand provides other benefits to your aquarium. Choosing the wrong one could result in significant losses—and you will end up wasting not just your money but your time and effort in setting up and maintaining the freshwater aquarium as well. So, make sure to compare your options carefully before making a purchase!
