Assumptions and source

  • The calculator uses 8.34 lb per US gallon as a fixed freshwater planning factor.
  • Actual water density changes with temperature, salinity, and composition.
  • Enter actual supported water volume, not the advertised aquarium capacity.
  • Other supported weight combines substrate, rock, wood, equipment, and other items above the stand.
  • The estimate excludes the stand weight.

WARNING

WARNING: Do not use this estimate as proof that a stand, floor, or other support is safe. A support failure can cause injury, flooding, or property damage.

This calculator does not evaluate stand construction, floor capacity, load distribution, support style, leveling, or building requirements.

This result is not a stand rating, structural approval, engineering approval, manufacturer approval, or code approval.
