When setting up a glass aquarium, it is important to make sure that it is properly supported. Without adequate support, the aquarium can become unstable and crack or break under its own weight. This can cause damage to your fish and tank accessories, as well as any furniture supporting the tank. One way to ensure adequate support for your glass aquarium is by using stands or cabinets specifically designed for holding an aquarium’s weight. Not only do these provide necessary support for the base of the tank but they also give you extra storage space for equipment such as filters and pumps. Additionally, when positioning a stand or cabinet beneath an aquarium make sure that it has adjustable legs so you can level out any uneven surfaces in order to prevent stress on the glass sides of the tank from one side sagging more than another. You should also consider placing some form of cushioning between your floor surface and wherever you are placing your aquarium stand/cabinet in order to reduce shock or vibration if anyone happens to bump into it accidentally; this could potentially lead cracking due to sudden impact on fragile materials like glass which cannot handle too much stress at once without breaking easily.. Lastly, avoid placing anything heavy near or above your tank because this could result in accidental spills damaging both the inside contents of your fish tank as well as any surrounding furniture pieces.
