Aquarium Gravel U914659

Gravel is an important part of every aquarium. It not only beautifies it, but provides a surface for the growth of beneficial bacteria which help to convert fish waste. Combining gravel with plants and decorations( which provide cover and hiding places) will create a healthy and natural environment for your aquatic creatures.A depth of approximately 2 inches (approximately 1 1/2 – 2 lbs) of gravel is recommended, especially when used with an undergravel filter.
