Things to Consider
Material: Glass or Acrylic
125-gallon aquariums come in glass and acrylic, and both materials are pretty sturdy when it comes to holding such a large quantity of water.
Let’s see the various parameters you must consider before making a choice.
One area where acrylic scores over glass are the weight since, for an aquarium this size, glass adds its significance along with the weight of water.
Acrylic, with its lighter weight, is a good choice for a 125-gallon fish tank. It is ten times lighter than glass, and redecorating or moving the aquarium becomes more accessible with the lighter weight.
The glass aquarium, along with the weight of the water, becomes too heavy and very difficult to handle.
The weight of 125 gallons of water is 1042.5 lbs (472.9 kg), and an empty 125-gallon aquarium weighs about 200 pounds (90.7 kg).
Add to it the weight of the substrate, rocks, decorations, filtrations, and the other aquarium equipment, and it would easily weigh close to 2000 pounds (907.2 kg)!
Acrylic also scores higher than glass when it comes to strength. Glass breaks or shatters easily. while acrylic does not. Large aquariums made out of acrylic are more resilient and do not chip easily.
However, acrylic does tend to get scratched if you use vital algae brush to clean the aquarium walls.
Glass aquariums in this size are rectangular as you cannot customize glass to take the shape of your choice.
On the other hand, acrylic is not as brittle and hard as glass and can be easily shaped. You can get your aquarium shaped as per your choice in these aquarium dimensions with acrylic.
A glass aquarium with curved edges tends to bend light at these edges, making the fish appear smaller or bigger than they are.
We feel that acrylic is suitable for aquarists who are DIY enthusiasts, while glass aquarium is perfect for beginners.
