Frequently Asked Questions (FAQs)

1. How long do glass aquariums last?

Glass tanks have a lifespan of seven to ten years on average. Every once and a while, you hear about someone with a fifteen year old tank, but it's not very common. Re-sealing can be done by yourself, but the tank must be taken down and emptied. An acrylic tank should last for a long, long time.

2. Which glass is best for aquarium?

Acrylic has more insulation capability and that can be a pro or a con depending on the room temperature and the aquarium temperature you are trying to achieve. The Good News: (1) Better clarity – acrylic allows more light through it as much as 93% where glass can be more in the 82% range.

3. Is glass safe for aquariums?

Glass – Plain glass is fine in an aquarium. Colored glass is usually safe too, as long as it is the glass itself that is colored. The risky part comes with glass that is painted or glazed.

4. What is aquarium glass called?

It is brittle, so it needs to be very thick to stop it from shattering and at such thicknesses, the high refractive index of glass distorts the view of the fish in the tank. Instead, polymethylmethacrylate (PMMA) is used. This is also known simply as acrylic or by its various trade names, such as Plexiglass and Lucite.
