Any new aquarium tank should first be given a thorough test to ensure that it is watertight. If after 12 hours there are no leaks, it may be emptied and placed in its final position.  

Now all is ready to set up the aquarium, for this work we shall require various items such as sand, rocks etc. These will be death with in order. For making a bottom soil, you need, first of all some sand, the most suitable is called 1/16th grade and it is about the size of the average pin-head:  

The gravel to be used must also be graded; that is, the gram must be of uniform size. Sand and gravels sold in aquarium supply stores are always graded, but if you buy elsewhere, they may not be. Gravel grains 2-5mm work best.  

If you use nothing, but sand, it must be well washed-in buckets, under running water until no more dirt or foam comes to the surface - and spared out on the bottom of the tank in a layer running from 3-6 cm thick sloping upwards from front to back. If you decide to mix the sand with gravel to make at least a layer 6 cm deep on top of the sub gravel filter since less than this amount reduces the filtering capacity of the tank.  

Your tank is the basic element, and is of course, the most important in building an aquarium. The size of the tank depends on the number and size of fish you plan to have in it. That is why proper planning is quite essential when you want to set up aquarium.  

But then it is important to make it as big as you can afford. By all means avoid a globe tank as much as possible. Rectangle shape is always good because of various reasons you will discover later.  

Option 1: You can buy readymade glass tanks already sealed professionally set up aquarium tank at any aquarium store.  

Option 2: Buy ready-made plastic models through distributors or mould-extrusion manufacturers and put your aquarium tank together yourself.
