Types of Aquarium Substrate and Their Uses

Aquariums are often setup with some kind of substrate covering the tank bottom. Aquarium owners have a broad range of options when setting up an aquarium since the substrate is available in a number of colors and materials. Before assembling the aquarium, it is advisable to take some time selecting the kind and color of the substrate because it is more difficult to modify than other aquarium components.

What is aquarium substrate?

The substance used to line the bottom of an aquarium tank is referred to as aquarium substrate. The correct substrate for your needs may improve the water quality, the habitat, and the wellbeing of the aquarium's inhabitants, even though it is occasionally only chosen for aesthetic reasons.

Purpose of Substrate

The substrate has a number of uses. While some are essential to a healthy ecosystem, others are purely decorative. It adds color to the aquarium to accentuate the concept, such as vivid colors for children's aquariums with castle or mermaid themes, or more natural brown gravel to match driftwood and live plants. Additionally, the growth of helpful bacteria that degrade the waste materials generated by the fish occurs in the gravel.

Bacteria Medium

The substrate contributes to the by functioning as a habitat for good bacteria to proliferate and flourish. Even while the substrate is not these vital bacteria's only host, it is where a sizable portion of them live. The substrate functions as a surface for living plants to take root and absorb nutrients in addition to serving as a home for bacterial colonies. There are specialized substrates that offer essential nutrients for use in aquariums with live plants.

Fish Habitat

For fish that prefer to burrow, substrate is particularly significant since it helps to create a more natural home for them. Animals that live at the bottom of the food chain like searching the substrate for food scraps that have fallen there. Because it does not reflect pictures of the other fish in the tank, like glass does, the substrate can help make fish feel safer. The substrate's spotted appearance also gives the fish a sense of security. Some fish species strew their eggs throughout the tank's bottom. The eggs are easily visible and more likely to be eaten by adult fish if the tank bottom is empty. The eggs will be more difficult to see if the substrate is spotted. Some eggs will fall in between the voids and be protected if the substrate is big enough.

Decoration

An aquarium's substrate helps to improve its overall visual appeal. Substrate aids in the creation of an eye-pleasing, peaceful visual environment when mixed with plants, pebbles, driftwood, and other ornamentation. People who look at a well-designed aquarium are known to have favorable health benefits. Selecting a substrate color that goes well with your fish might help bring out the colors in them.

Substrate Materials

There are many other types of substrate available, but the majority of aquarium owners choose for the ordinary gravel found in pet stores. Sizes, hues, and even forms may all be found in gravel. Next most popular substrate type is probably sand. Sand substrate is particularly favored by fish that like to dig. Crushed coral is another popular substrate that has the effect of boosting pH and enhancing the water's ability to act as a buffer. African cichlids, for instance, require argonate gravel, which is rich in calcium and helps control the pH of their aquarium.

Sometimes, a large river rock is utilized alone or with gravel underneath. The rock provides a beautiful, natural backdrop. However, marbles are not a natural substance. However, they are frequently employed for producing fish species that spread their eggs. The adult fish, who would ordinarily love eating the delectable freshly deposited eggs, won't be able to get to the eggs because they will fall between the marbles. In Betta fish aquariums, marbles are also utilized, making upkeep simple.

It is typical to use laterite or vermiculite as a substrate while keeping live plants in aquariums. These substances have the capacity to retain and release vital nutrients for living plants. They are often utilized as the substrate's lowest layer and are covered in a layer of gravel.

Substrate Quantity

Typically, the substrate is filled to a depth of around 2 inches. When there are living plants present that create a strong root system and require the additional depth, it may be justified to dig deeper. The depth is typically between 1 and 1 1/2 inches when utilizing sand. More than that may result in dangerous anaerobic zones in the gravel. The same is true for gravel substrate that has been filled too deeply.

Substrate Color

Discussions over color are frequently contentious. Others pick a substrate color based on personal choice, such as vivid pink, neon blue, fire engine red, and a variety of other hues. Some people firmly believe that substrate color should match natural environments. Although it is obvious that those are not the colors that fish would naturally see in the wild, the aquarium's occupants won't be harmed by them.

The color of the substrate is a non-issue if you take appropriate care of the fish. The majority of fish are fairly adaptive, so as long as they are kept in well-kept tanks with appropriate food and water, they will thrive no matter what color the substrate is.

Substrate Maintenance

Whatever kind of substrate you choose for your aquarium, it's crucial to routinely remove any waste that could amass there. Using a specialized aquarium gravel vacuum, which will remove the dirt from the substrate without disturbing the substrate itself, is the simplest way to accomplish this. These may be found at your neighborhood fish store and should be used once or twice a month while changing the water in your aquarium partially.
