Why Do You Need Gravel in Aquarium?

Plenty of reasons will confirm that you’ll need gravel in your aquarium. The obvious reason is that use of gravel increases aesthetics of your aquarium, meaning the aquarium will look fantastic with gravel.

You may have seen how aquariums in your friends’ home pop with bright colors. If you want to achieve a unique look of your tank, now is the best time to get gravel.

Whether you want to make your tank more natural, or are looking for an authentic look, gravel (substrate) will make things pop. Trust me, your aquarium will look better significantly with gravel in the bottom.

Moreover, gravel is required for performing many functions. You will need to place gravel in your tank because gravel anchors down aquarium plants. Plants will root and thrive when placed in gravel.

Gravel also enables beneficial bacteria colonies to grow. The bacteria keep the environment in your tank healthy by accommodating the nitrogen cycle.

On the other hand, small and compact gravel limits space for detritus to hide. Detritus accumulated will end up polluting the environment. So, it’s a pretty good reason to keep your aquarium clean and achieve balanced water.Best Aquarium Gravel

What to Look for When Purchasing an Aquarium Gravel?

When looking for the best aquarium gravel, you need to consider many crucial factors. These factors can make or break gravel. So, it’s important that you study these factors. Let’s find out what these factors are.

Gravel Size

Smaller gravel or large gravel?

There are pros and cons for each of these gravel sizes. For water flowing downwards, there can be a problem with small gravel.

Small gravel may be an excellent choice in case of snails and ground walkers. Most fish actually favor smaller gravel. Smaller gravel may need less maintenance. However, it’s really difficult to clean tiny gravel.

For free swimming fish, Plecostomus, and shrimp, large gravel will be a better choice. Besides, some fish like to munch on large gravel. There’s an added benefit with fish munching on larger gravel as they are likely to cause algae.


Just choosing a random color won’t cut it if you prioritize aesthetics. Slight miscalculation with color may devalue efforts you invested in the beautification of the gravel.

Green gravel imposes a beautiful, rich background. Choosing black color is a no-no if you have dark fish in your tank. You may select a color that you don’t see every day or mix two colors.


Depth is dependent on the number of live plants and scavengers. If you have a tank full of plants, then a 3-inch deep bed could be the perfect choice. But, if you have a few live plants, then go for an inch depth.

pH Value

Aquarium gravel is highly unlikely to change the pH level in your aquarium water. However, some gravel comes with clear instruction that may alter the value of PH and lead to water hardness.

Final Thought

The best aquarium gravel will make your aquarium stand out and meet your needs. It will promote growth of useful bacteria, leading to a healthy ecosystem thereby. Whether you have a saltwater or freshwater aquarium, you need to set up gravel. The recommendations in this article are up to the task. Additionally, I discussed a few buying guide factors. You need to consider shapes, sizes, colors, and fish requirements to eventually choose gravel.

Next, you have a flawlessly built unit that is good for all the inhabitants in the aquarium as well as for plants. Overall, the gravel helps keep a vibrant environment. It sets the mood in your aquarium and is easy to use as well.
