Aquarium Rack Sizes and Matching Aquarium Shelf Weight Capacities

It's essential to consider an aquarium's weight when filled with water and substrate rather than its weight when empty. Even if an aquarium's size suits a table or stand, its filled weight might be too heavy for some furniture. A gallon of water weighs about 8.34 pounds, which means that 180-gallon aquariums can weigh more than a ton. The weight of an empty aquarium varies depending on its material and accessories. For instance, acrylic aquariums weigh slightly less than glass aquariums of the same size. It's best to calculate the filled weight of the aquarium you want and ensure that the aquarium stands you can handle.

Ensuring your aquarium rack's shelving units can support your aquarium's weight is essential. To make this easier, you can use the following chart as a quick reference guide for matching fish tank rack sizes with corresponding aquarium shelf weight capacities:

Rack Size

Shelf Weight Capacity

Ideal Tank Sizes

Small (60cm - 90cm)

175kg per tier

10-30 gallon aquariums

Medium (90cm - 120cm)

265kg per tier

30-75 gallon aquariums

Large (120cm - 150cm)

300kg per tier

75-150 gallon aquariums

Extra Large (150cm+)
