To discover the real total weight of a set-up aquarium, one must account for 4 primary elements:
The standard formula appears like this:

Let's break down each part to see how they add up.
To make planning simpler, the table below describes the approximated filled weight of common aquarium sizes. Keep in mind that these numbers assume basic glass tanks filled with water, a normal layer of gravel, and standard design.

|---|---|---|---|---|
| 5 Gallon | 16" x 8" x 10" | 7 lbs | |55 pounds | |25 kg |
| 10 Gallon | 20" x 10" x 12" | 11 lbs | |110 pounds | |50 kg |
| 20 Gallon High | 24" x 12" x 16" | 25 pounds | |225 pounds | |102 kg |

| 125 Gallon | 72" x 18" x 22" | 215 pounds | |1,400 pounds | |635 kg |
Keep in mind: Acrylic tanks are usually 40% to 50% lighter than glass tanks of the very same volume, though the water weight remains similar.
While water constitutes the large majority of an aquarium's weight, the interior elements can include an unexpected variety of pounds to the last tally.
Most aquariums need a 1-to-2-inch layer of substrate.
Guideline of Thumb: For a basic 55-gallon tank, plan on adding 50 to 75 pounds of substrate.
