Low iron glass, on the other hand, is much clearer and doesn’t have the green tint of regular float glass. This makes it an excellent choice if you want to showcase your fish and aquatic plants with the utmost clarity. However, it is more expensive than regular float glass.

Lastly, tempered glass is much stronger and more durable than the other options, making it a wise choice if you have large or aggressive fish that might bump into the glass. That being said, it is also the most expensive option. Ultimately, the right choice for you will depend on your budget and the specific needs of your aquarium.

Advantages and Disadvantages of Glass Types

When choosing the right glass for your 200 gallon aquarium, it’s important to consider the advantages and disadvantages of the different types of glass available. Tempered glass is stronger and more resistant to scratches and impacts than regular glass, making it a good choice for large aquariums. However, it cannot be cut or drilled once it’s been tempered, which can limit customization options.

On the other hand, regular glass is more affordable and easier to customize, but it’s not as strong as tempered glass and not recommended for larger tanks. Acrylic glass is another option that is lighter and more impact-resistant than glass, but it can scratch easily and is often more expensive. Ultimately, the right choice will depend on your individual needs and preferences.


In conclusion, the thickness of the glass for a 200-gallon aquarium is not a matter to be taken lightly. It is crucial to ensure that the glass is thick enough to withstand the pressure of the water and the weight of the inhabitants.
