From the days of glass tanks in the 60’s and 70’s with the metal frame tanks that were very heavy is unsightly to the eyes, technology has improved and other materials can be used for creating your dream aquarium. Now 20 gallon aquarium come in all shapes and sizes due to the new technology of acrylics and plastics.
20 gallon glass aquariums are still the most popular form of tanks available in the market. The basic construction is plate glass sealed with a non toxic silicone. The glass can be either tempered (stronger, lighter and will shatter into pieces when it breaks) or plate (heavier, thicker and will crack when it breaks).
The frame of the glass will be pre-drilled allowing for your equipment and hoses to be concealed behind. Typically these tanks will cost more to buy and it’s not a necessary to have.
Big disadvantages of these tanks are that are limited in the shapes they can be formed, limited to rectangle and squares and if your want an unusual shape then glass is not for you.
20 gallon glass aquariums kit are also very heavy in nature, due to the glass thickness increasing when the tank gets bigger and larger. The loading on the floor can be increased with an glass aquarium so ensure your floors can take the loadings and not recommended upstairs. Glass tanks can break and shatter easily and you can end up with a wet floor and a lot of dead fish.
Testing and Repairing a Leaking Tank

Purchase a good aquarium sealer and apply to the affect areas and let dry for at least 48 hours before adding the water again. Repeat the test again to ensure the leak is sealed.
