Thanks for the advice. However, I would think that 6mm is way too thin to hold so much water.
Do you know of a good bonding material that holds together acrylic?
I would like to build an aquarium. The sizes are: height 140cm (4.5 feet), length 120cm (4 feet), width 100cm (3.3 feet).
The material has to be 20mm thick acrylic (preferably tinted light blue).
I need advice on which kind of glue can hold this together and whether it needs to be strengthened...
