Why is a substrate important for your aquarium?

If you are wondering why a substrate is very important in an aquarium, this is the section that you have to read. Substrates are used for four important reasons. They are:

Biological filtration purposes–Your aquarium plants need substrate as they are prone to witness a lot of plant debris, food leftovers and the waste of the fishes. These need to be eliminated to safeguard the overall hygiene of the aquarium. When you choose the right substrate, good bacteria grow and colonize on them. These colonies then naturally eliminate the waste products, thereby keeping the tank absolutely safe.

Creating natural habitat for the fishes – Substrates are available in different types to mimic the natural habitat of the different types of fishes. This will make the fishes feel comfortable when they are inside the tank, so that they are stress-free and healthy.

Encourage growth of plants–When you have a planted aquarium, it becomes imperative for you to invest in the right substrate. This is because the plants grow well on these substrates, thereby keeping your tank fresh and odor-free.

Decorative purposes – Last, but definitely not the least, a substrate is important to decorate your aquarium and make it look visually appealing to your eyes.
