  • First when it comes to deciding the transparent material for fish tank walls, there are two options, plain glass or acrylic sheet. The bigger the tank you want the thicker this sheet will be.
  • The bonding material that keeps the volume of the tank intact. To make this work you’ll need a good quality aquarium safe sealant that does not go off after a few days.
  • Next you’ll need all the necessary tools that you must be skilled to use so that you can cut the glass or acrylic sheets of the correct sizes and build it yourself.

In short, you need some extra special skills to build it yourself at home and even if you build it home it must be of top quality and durability because there is no room for error here.

If something goes wrong and it start leaking, then you’ll have a hard time shifting all the beautiful fish and tank decorations elsewhere disturbing the habitat and this can be dangerous for fish. Some fish are very sensitive and cannot take the slightest change in lighting conditions, water temperatures and water chemistry etc.
