how much gravel do i need for a 40 litre fish tank

by Mrs. Berneice Hauck Published 4 years ago Updated 3 years ago

As a general rule of thumb, I recommend adding 1-2 inches (2.5-5 cm) of gravel to your fish tank. This means, that you will have to get about 1-2 pounds of gravel per gallon of water volume. So a 40 pound (18 kg) bag of gravel should be enough for a 20-40 gallon tank.

To calculate the exact amount of gravel required, you will multiply the depth of the aquarium by inches by the amount of gravel you have calculated per inch. You can also use an Aquarium Gravel Calculator to help you solve this easily. Generally speaking, you should add about 1 pound of substrate per gallon of water.
