The Aquarium Stand
If you do not wish to place the aquarium on a cabinet, you will need a suitable stand. It must be extremely stable and evenly horizontal. A spirit level is invaluable. A 5 mm. Styrofoam panel must be placed below the aquarium to offset any distortion of the construction and to avoid tension causing cracks in the glass !

The power supply
You will need multiple outlets of electrical supply near to your aquarium. Filter, the heater, lighting, etc, are required for the installation of the aquarium. If possible, the power supply should be above the aquarium to avoid water spills into the outlets during water change or refilling.

The Cleaning & checking for water leaks
Aquarium sold nowadays come with safety standards. However, you should check the panes and the glue seams for manufacturing defects. There should not be gaps between the silicon and the glass. You can best carry out this check while cleaning. Before you set up the newly purchased aquarium, clean it thoroughly to remove residues from its production.
You will need one or two buckets, strictly for cleaning and maintenance purposes. These buckets should never have contained or rinsed with cleaning agents, detergents or other chemicals.
Chemical glass cleaners should not be used on the glass panes, including the lid and on the outside. By mistake, minute cleaning detergents can easily cause contamination in the aquarium.

Clean the aquarium thoroughly with hot water. Add some drops of sera pH-minus onto a firm cloth or sponge to wipe the glass. Attention: Many sponges are not suitable for aquarium use because they already contain cleaning agents or detergents.

After the aquarium is cleaned, fill it with water and observe for leaks. If leaks do not occur after 2 to 3 hours, the aquarium is leak-proof.
