A 55 gallon fish tank is about 48 inches long, 13 inches wide, and 20 inches tall. The average weight of a 55 gallon fish tank full of water is about 450 pounds.

## Gallon fish tanks come in a range of weights

“A gallon fish tank generally weighs between 4-10 pounds (1.8-4.5 kg). The weight of the tank will depend on the size and type of fish you have, as well as how much water you have in it. A full gallon fish tank can weigh up to 10 pounds (4.5 kg).”

## The weight of your tank depends on the material it’s made from

If you’re wondering how heavy a gallon fish tank is, the answer depends on the material it’s made from. For example, a glass tank can range from 10 to 30 pounds, while a plastic one may weigh as little as 5 pounds.

The weight of your tank also affects where you can put it. A heavier glass tank may need to be placed on a stand, while a lighter plastic one can be easily moved around. Be sure to consider the weight of your tank when deciding where to put it in your home.

## How to calculate the weight of your tank

To calculate the weight of your gallon fish tank, you will need to know the dimensions of your tank. The weight of your tank will be:

Length (in inches) x Width (in inches) x Height (in inches) x 0.004329 = Weight in pounds

For example, if your tank is 24″ long, 12″ wide, and 12″ tall, the weight of your tank would be:

24″ x 12″ x 12″ x 0.004329 = 52.68 pounds

## What factors affect the weight of a 55 gallon fish tank?

There are a few factors that come into play when determining how much a 55 gallon fish tank weighs. These include:

The type of material the tank is made out of – glass is going to be much heavier than acrylic, for example.

The weight of the water – a gallon of water weighs around 8.3 lbs.

The weight of any decorations or gravel you have in the tank.

So, taking all of these factors into account, we can say that a typical 55 gallon fish tank will weigh somewhere between 50-250 lbs.

## Conclusion

A 55 gallon fish tank is quite heavy, weighing in at around 150 pounds when empty. However, when filled with water, gravel, and decorations, the weight of the tank can increase to over 300 pounds. This makes it important to consider the location of the tank carefully before setting it up, as you will need to make sure that the floor is able to support the weight of the full tank.
