Thicker glass provides a greater margin of safety and reduces the risk of leaks or cracks.

The sealant must be aquarium-safe, non-toxic, and applied meticulously to create a watertight seal between the glass panels. Look for tanks with clear, uniform sealant lines, free from bubbles or imperfections. A good sealant will prevent leaks and maintain the tank’s structural integrity for years.
**Frame material:** Most 100-gallon tanks come with a top and bottom frame to provide additional support. The frame material is typically made of plastic or metal.
