Gravel plays a crucial role in maintaining the health and stability of a 5-gallon aquarium tank. The size and type of gravel are significant factors to consider when setting up an aquatic environment. Proper fish tank gravel provides a substrate where beneficial bacteria can thrive, contributing to the biological filtration process, and helps remove excess nutrients.

Choosing the correct size of gravel is important to prevent choking hazards for smaller fish or blockages in the filtration system. The right fish tank gravel allows for proper water flow through the substrate, fostering a healthy environment for both your fish and the beneficial bacteria that contribute to the tank’s ecosystem.
