Aquarium Weights & Sizes

aquariums are heavy

Aquariums are actually quite heavy on their own.  Then, add in some sand or rocks, a few decorations, then fill it with water, and you've got a potentially floor-busting behemoth on your hands.  It's important to know what you're getting into, and make sure you have a stand that can hold the weight and that your floor will also be able to hold the immense weight.  The last thing you want, is your brand new 180 gallon aquariums smashing through the floor into your basement!

 

Below is a chart that shows the sizes and weights (both empty and filled) of some of the most common aquarium sizes.  Notice the HUGE difference between empty and filled weights.  The 55 gallon is one of the most common larger aquariums sold in America - and when full it weights over 600 pounds!!!  That's why it's CRUCIAL to buy an aquarium stand made specifically for that type of tank - standard furniture cannot handle that kind of load for extended periods of time.
