How to calculate how much soil do you need:
Length cm x depth of the aquarium cm x substrate height in cm: 1000 = result in liters
E.g. Aquarium with bottom dimensions 100 x 40 cm, required substrate height. The depth of the substrate at the front should be about 2 cm, with the back wall 7-8 cm, the diameter being 5 cm. For stock substrates, you need 2-3 cm.
100 x 40 x 5: 1000 = 20 l substrate
