For fresh water, the principle is 8.34 lbs per gallon.(Note: Saltwater is slightly denser, weighing roughly 8.55 pounds per gallon due to liquified salts).
To give a clearer image of what to expect, the table below lays out the estimated filled weight of common aquarium sizes. These computations assume fresh water, a standard 2-inch substrate bed, and common rock/wood hardscaping.
| Tank Size (Gallons) | Empty Tank Weight (lbs) | Water Weight (lbs) | Substrate & & Hardscape (pounds) | Total Estimated Weight (pounds) | Total Estimated Weight (kg) |
|---|---|---|---|---|---|
| 5 Gallon | 6 | 42 | 8 | 56 pounds | 25 kg |
| 10 Gallon | 11 | 83 | 15 | 109 lbs | 49 kg |
| 20 Gallon High | 25 | 167 | 30 | 222 pounds | 101 kg |
| 29 Gallon | 40 | 242 | 45 | 327 lbs | 148 kg |
| 40 Gallon Breeder | 55 | 334 | 60 | 449 pounds | 204 kg |
| 55 Gallon | 78 | 459 | 80 | 617 pounds | 280 kg |
| 75 Gallon | 135 | 626 | 110 | 871 pounds | 395 kg |
| 125 Gallon | 220 | 1,043 | 180 | 1,443 lbs | 654 kg |
Disclaimer: Weights can differ based on the particular density of the glass, the type of stand used, and whether the tank is rimless or braced.
When planning an aquarium develop, numerous particular style choices will swing the final weight calculator results up or down.
As soon as you have actually utilized an aquarium weight calculator and know your tank's total footprint, run through this important safety list to safeguard your home and your pets:
