Large scale aquariums made from insulated glass should be secured by placing them in stabilizing frames. This is due to technological conditions, such as the aging of silicone. This is especially prevalent is sea aquariums.
To avoid cutting and re-glueing that should be performed every seven years, we recommend placing the panels in frames. Not only does it increase the safety associated with lesser hydrostatic pressure, the use of frames also lessens the risk of mechanical damage to the tank while using and maintaining it. Damaging the tank by breaching of the panels of the aqarium is almmost imposible, however, so called “pinching” of even very small pieces of glass on the edge of the aquarium is very common. Each such damage can lead in time to rupturing of the panel – the rupture starts from such a “pinch”.
We’ve seen examples of such dameges, from accidental hitting with a ladder, chair, or even a ceramic cup. Additionally, closing of the tank with typical glass clips, vertical and horizontal, carries a neccessity of further care when maintaining such tank. A sudden break in one of the stashes will cause a violent change of forces that will usually lead to breaking out of one of the panels. When using a steel frame the top of the aquarium is fastened with steel clips and corrected with roman screws.
Smaller tank (up to 400cm in lenght) can be made in our workshop, test filled and transported to our client. On standard frames up to 300cm in lenght we place anodized alluminium frames produced by Akvastabil, on larger aquariums we use steelk frames that are painted in layers. Their thickness depends on ous construction calculations. Frames are also neccessary wyth large scale acrylic glass aquariums. Even though silicone is eliminated here, acrylic glass is less rigid than glass, and frames secure the panels from bending outwards.
