5 Customer Questions
How often should i change it?
To provide a 2-3 inch depth for a Butterfly Agama lizard in a 36" by 18" tank, how much of this substrate is needed?
Answer by • Sep 28, 2021
The depth of substrate that you need depends on several factors, including the size, volume, and depth of your tank. Generally speaking, you should add about 1 pound of substrate per gallon of aquarium. For example, this means that for a 5-gallon aquarium, a safe bet would be 5 pounds of substrate for 1 inch depth or 15 pounds for a 3 inch depth.
