How Much Sand Does a 75 Gallon Need?
A standard 1.5-inch bed requires approximately 70 lbs of aquarium sand or 35 L of active aqua soil.
Customize Substrate Bed →Floor Load & Stand Safety
At approximately 765 lbs, the 75 Gallon exerts a specific pounds-per-square-foot (PSF) structural load on your home's flooring. The footprint area is 6.00 sq. ft, meaning the raw PSF is roughly 128 PSF.
Heavy Load Warning: This aquarium size requires caution on upper-level floors. It is highly recommended to place this tank perpendicular to structural joists rather than parallel to them to distribute the load across multiple beams.
