Best Aquarium Sand for Freshwater and Saltwater Aquariums
During my early years as a fish keeper, I was super fascinated with the shiny sand, mysterious pebbles, and the plants at the bottom of a fish tank waving to a silent rhythm. Until I realized it is not merely for aesthetics, but aquarium sand serves an essential purpose in the overall ecosystem. Back then, the aquatic substrate simply meant adding colored rocks and gravel at the bottom of your fish tank. However, things are different now; the aquarium substrate has evolved, available in various sizes, shapes, and materials.
Aquarium sand or gravel is not universal for all fish tanks meaning, the best substrate for saltwater aquariums might not be suitable for freshwater fish tanks. Similarly, the best substrate for goldfish might harm your betta fish. Sounds overwhelming? We will break it down for you in this article. To help you make a better decision for an ideal fish keeping experience, we have cleared some of the significant deliberations in the fish keeping community such as- sand vs. gravel substrate. Once that’s done, we have the best aquarium sand based on the tank type and different fish breeds. Let’s start by understanding the utility of aquarium sand in a fish tank.
Why Do I Need Aquarium Substrate in My Fish Tank?
Before we tell you about the benefits of adding aquarium sand or gravel to your fish tank, we know many of you might be wondering, “what is aquarium substrate”? Well, you probably already know what aquarium substrate really is. But that’s just not how it commonly referred to as. You might be more familiar with aquarium gravel or aquarium sand- the matter that forms the bottom-most lining of your fish tank!
The type of material you use for lining the fish tank has a significant impact on the aesthetics of your overall aquarium ensemble. It also determines the health scale of your fish tank’s inhabitants. Here are a few factors that explain the benefits of adding an aquarium substrate to your fish tank:
- Supplements the nitrogen cycle of your aquarium
Aquarium sand holds healthy bacteria that maintain the nitrogen cycle in your fish tank. While your filtration unit is the most saturated with the ‘good bacteria,’ aquarium substrate comes second. Moreover, if you are thinking of adding another tank to your collection or just beginning with the hobby, aquarium sand accelerates the curing process of the fish tank and prepares it to house the fish much more quickly.
- A natural habitat
Have you seen a natural aquatic habitat with a glass lining at the bottom? The concept is that simple! Aquarium sand lining your fish tank helps mimic the natural habitat and ensures stable conditions given proper fish tank maintenance is provided.
- Your aquarium plants need an anchor.
Most fish keepers discover that they need aquarium sand or gravel when they realize in the absence of it, their aquarium plants will float on the surface instead of standing at the bottom. In case you are just starting with the hobby, that’s a heads up to include aquarium sand in your list of items if you are planning to do aesthetically pleasing aquascaping with aquarium plants in sand.
- Better fish visibility
Certain fish breeds are naturally equipped with colors that make them inconspicuous- an inherent quality for survival in a natural habitat. But in the safety of an aquarium, you need something to make your fish noticeable. The light-colored aquarium white sand serves as a great contrast enhancing the visibility for darker fish breeds and vice versa.
The above factors make it fairly clear that your aquarium ensemble will be awfully incomplete without fish tank sand lining the bottom. If you agree, check out the best sand for aquarium for a stunning fish tank aesthetic.
Aquarium Sand VS. Gravel – Which is better?
Deciding the best types of aquarium substrate is a preliminary and mind-boggling quandary that every fish keeper must face. Landscaping a sand or gravel aquarium is more than just aesthetics; it affects the entire set up and the health of your fish tank’s inhabitants. Here is a little showdown that will perhaps answer the age-old debate – is sand better than gravel in aquariums?
The benefits of using sand for aquarium
One of the major benefits of using sand for fish tanks is that it imparts a vivid yet smooth mien to your ensemble. The appearance mimics the natural pond set up quite well while also preventing the build-up of sinking debris and detritus. It is easy to clean, maintain with a gravel vacuum. Sand is a more desirable choice for fish keepers who are keen on housing freshwater aquarium species, including goldfish, cichlids, and fish that burrow in sand such as geophages and clown loaches. Moreover, compared to gravel, aquarium sand does not require frequent water changes.
The benefits of using gravel for aquarium
Gravel is better as an aquarium substrate in terms of maintenance for freshwater tanks. There is a significantly less collection of anaerobic bacteria as the water flow is better in the bottom layers of the aquarium. Moreover, since the gravel is considerably heavier than sand, it does not accumulate in the filters.
The middle ground
If you are still unsure about making a dedicated choice, you can go ultra-diplomatic and create a sand and gravel aquarium. Aquarium sand and gravel mixed can only be used if you are not using gravel filters as the motor will be working too hard to keep the water clear, ultimately reaching its end of use a little too quickly.

Fish Tank Maintenance- Cleaning Aquarium Sand
Once you begin using sand in an aquarium, you quickly start fretting the imminent question of how to clean sand for aquarium? If that’s what keeps you from creating a stunning landscape in your fish tank, here’s a little brief on the simplest methods of cleaning an aquarium sand fish tank. As a beginner, the endeavor sounds even more overwhelming, but there is no special equipment needed besides aquarium gravel to conduct proper fish tank maintenance. Follow along.
Equipment you will need
- Gravel vacuum
- A large container or tub
- A stick to stir the contents of the fish tank
- Begin by siphoning out the water from the aquarium into a tub or a large container with the help of a gravel vacuum. You will need to position the farther end of the vacuum at the very bottom of the fish tank. Once you power up the vacuum, move it around the entire length of the tank to find the perfect height where the water is getting filtered out. It is crucial to position the vacuum at such a height where the aquarium sand is not getting sucked along with the water.
- A rule of thumb is never to place the vacuum too close to the aquarium sand since all the debris and the residue is settled on its surface. Moreover, the goal is to separate the fish tank water from the aquarium substrate.
- Using a stick or a rod, stir the sand around a bit to break the layers so that all the anaerobic nitrifying bacteria are exposed along with the decaying substances. When the sand is not stirred, the dead matter remains trapped within the layers causing the water in the tank to become murky quickly, which also invariably hampers the chemistry of the ecosystem. We recommend stirring the aquarium sand several times before you wrap up the vacuuming process.
- If you wish to be meticulous and ensure that all the harmful bacteria are siphoned, it is better to keep the sand in the sun for a day or two.
- Water changes and aquarium sand cleaning are a prerequisite for healthy aquarium water parameters. It is vital to conduct fish tank maintenance at least twice a month. The more frequent you are, the less work you will be doing.
Best Aquarium Sand – Buyers Guide
While you are contemplating the best aquarium sand, there are many considerations to make for fruitful investment. There are several types of aquarium substrate that make choosing the right aquarium sand quite overwhelming. Here’s a simple buyers guide that you can use to assess the quality and suitability of your aquarium substrate for an ideal fish keeping experience.
The type of aquarium sand you use matters a lot
- Live sand
Live sand comes straight from the ocean bodies; it contains remnants of several living microorganisms collected while it was being extracted. Live sand is the best form of natural aquarium substrate as it does not contain any toxic elements such as purifiers, dyes, and other factors. Using live sand for a marine aquarium is an excellent way of maintaining balanced water chemistry in your aquarium. However, due to pH altering properties, using live sand for freshwater aquarium is not practical.
- Play sand
A lot of fish keepers wonder if they can use play sand in an aquarium. Initially, play sand for aquarium might seem like a plausible option considering how cheap it is, but you will soon realize it has more drawbacks than any other type of aquarium sand. Play sand contains a large reserve of harmful elements, including silica or calcium carbonate, which will put your aquarium fish and plants at risk. Moreover, the grains of play sand are quite fine, meaning it will cause the water to become murky quickly. Play sand also facilitates the formation of harmful bacteria in the fish tank. If you still wish to add play sand in fish tank, make sure you conduct water changes more frequently and only turn on the filter when the sand is completely settled at the bottom.
- Pool Filter Sand
Pool filter sand is not specially curated as aquarium sand. However, the large grain sand measuring up to 0.45mm per grain is considered a virtue in terms of better tank water transparency and faster settling time. Using pool filter sand for aquariums is still not ideal as it might contain elements including hydrogen sulfide, which is toxic for your tank’s inhabitants. Moreover, there is a lack of color choice, which you quickly get in typical aquarium substrates.
- River sand
River sand is a classic aquarium substrate, which also a budget option if you wish to line your fish tank with a budget natural aquarium sand. The only parameter you need to keep in mind is that the product you choose is devoid of clay. Another disparity with using river sand for aquarium is that it takes a lot of commitment to clean and maintain. We do not recommend using this type of sand for aquarium if you keep bottom-dwelling fish species as the grains generally have sharp edges. On the good side, the large grain size allows for optimal airflow, thereby ensuring proper aeration, which is a vital factor for any aquarium ecosystem.
- Marine sand
A good quality marine sand is collected from the deepest parts of the ocean, which is a depth of around 30 to 60 feet. The naturally existing aquatic organism in the marine sand supplement the aquarium cycle. The most significant disparity with using marine sand for aquarium is that you will have difficulty finding the legit type. Mostly, sand picked from beaches is sold as a marine substrate, not ideal for a fish tank. However, if you do manage to get your hands on premium quality marine sand, your aquarium will indeed thrive like never before.
- Quartz Black Sand
The black fish tank sand gets its midnight black hue from minerals, including magnetite, hematite, or ilmenite. Quartz black aquarium sand is perfectly pH neutral, meaning it is a risk-free investment, albeit an expensive one. Another plus point about maintaining a quartz sand aquarium is that your fishes are considerably visible due to the dark background, which is perfect when we are talking about that jaw-dropping aesthetics.
It’s hard to ignore the budget
Cost is the ultimate parameter that will affect your decision while purchasing aquarium sand. It is vital to keep the budget in mind but cutting too much on the cost means compromising on the quality and health of your fishes. Before you make a final decision, it is best to compare various brands offering similar aquarium sand types with their price points. Certain reputable brands mentioned on the list do deliver premium quality aquarium substrate within a budget.
The pH balance and The Good Bacteria
Maintaining the right water chemistry within your aquarium is a hassle for every fish keeper, especially when you are landscaping or aquascaping the setup. The most foolproof method of ensuring the complete well-being of your fish tank’s inhabitants is to use a pH neutral aquarium sand. The same precaution applies to additives that your aquarium substrate comes with. Good quality sand, such as marine sand, will have a good number of healthy bacteria that will reduce waste and reinforce the nitrogen cycle. On the other hand, aquarium sands coated with dyes and other chemicals quickly become the main reason behind a fish keeper’s nightmare.
