Aquarium Substrate Calculator

This tool calculates how much substrate you need for a planted aquarium. Enter the length and width and desired height of the substrate. Select a substrate type or enter the liters per bag of your desired substrate. Typically, the substrate height ranges between 2-4 inches (5 to 10 cm). If a sloped substrate is desired, enter the average of the greatest and lowest height of the substrate.

The volumes from the substrate types in this calculator are gathered from product descriptions, manufacturer websites, and/or personal measurements of the product. They can be found below.
