I have only ever used glass aquariums, those boxes glued together with silicone. They are immensely strong and long lasting though there can be problems.
The potential problems with a glass aquarium such as a crack or silicone failure (been a bit too hasty with that razor perhaps!) have been dealt with in another text. The requirements for construction have also been covered, such as glass thickness and silicone application.
There is another type of aquarium that is widely used and they are acrylic. It seems only fair to produce a text that deals with the construction and potential problems of those too.
As said I have only used glass aquaria. The only thought in my head for dealing with say a crack (split?) in an acrylic aquarium is to apply heat or a solvent – that could be totally wrong.
My only option was to find somewhere that had good information on acrylics. So onto that wonder of today the internet to search, and after several comparisons the text I sought was found.
Information on how the aquarium should be constructed is given, allowing a judgment to be made before purchase. In addition, there is information on potential problems such as cracking and crazing.
Incidentally, it’s advised that the most common failure with an acrylic aquarium is because the aquarist has placed a metal halide bulb directly above an aquarium strut. Metal halides give out a lot of heat!.
Anyway, here’s the link:
