The size of the aquarium is of utmost importance in determining the time required for care, types of fish, arrangements and equipment that we will need. Contrary to the common understanding, in fact, the larger the aquarium, the easier it is to maintain and the need for intensive maintenance to be less frequent.
Let's start with what the nitrogen cycle means. In nature there is a continuous exchange of water and substances, which ensures good development of benefitial bacteria and biological balance in the eco-system. Briefly, fish eat, respectively, generate waste. These waste, in turn, produce large amounts of ammonia. It is extremely poisonous to fish and can lead to a decrease in immunity, and in severe cases to ammonia poisoning and death. Here is where the above-mentioned bacteria come. They are basically two types. The first converts ammonia into nitrites and the second nitrite into less dangerous nitrates. In nature, nitrates are absorbed by plants, and in the aquarium we regulate their level by regularly changing some of the water.
The aquarium is a closed system. Accordingly, we must provide equipment and methodology with which to re-create the appropriate conditions for life. In small aquariums, the nitrogen cycle could be started faster than those with a larger volume of water. This is because larger aquariums require more bacteria. This, however, is the opposite of maintaining the balance. In the small aquarium, more frequent water changes are needed, b.c. dangerous concentrations of harmful substances are reached much faster.
The frequency of water change depends entirely on the volume of the aquarium, filtration and load the tank. The larger aquarium is easier to maintain low levels of harmful substances.
Filtration of the aquarium can be mechanical and biological. Mechanical belong to all kinds of sponges and pads, they removed larger waste. Biological are all types of media (eg zeolite, matrix, biobolites, etc.) that serve as the home of beneficial bacteria. In tanks with a volume of up to 100 liters are most commonly used internal filters, and for aquariums with a volume above 100 liters - external filters.
If you want an aquarium with natural plants then you should keep in mind that an aquarium height of more than 50 cm is not recommended. In such a case, you will also need to provide a much more powerful lamp to provide the necessary light. For aquariums with lots of vegetation, the ideal volume is between 50-150 l and 30-45 cm hight.
Another important thing when choosing an aquarium is what fish you want to grow. You must first explore what volume and conditions are needed for the fish. Also how big they will become when they grow up. Many people hurry up and take a small aquarium with a volume of about 4-8 liters, buy a few goldfish, and up to a few months, the fish have overgrown the aquarium, and given the heavy workload, meanwhile, very frequent water changes were needed.
Here is a simplified table of basic requirements and features for the most commonly bought fish.

Last but not least consider the position of the aquarium. The location of the aquarium should not be near a window, because direct sunlight causes the development of algae. It should also be far from any sound systems, b.c. vibrations can stress the fish and even lead to rupture of the aquarium.
The rack or cabinet, on which will be placed aquarium must be absolutely flat and smooth. No bumps such as screws, cracks and edges are allowed. The aquarium should not exit from the surface. The rack should be absolutely stable and strong enough to withstand the weight of the tank. You can easily determine the weight by multiplying the aquarium liters by 1.3.
Example: 50l aquarium and equipment would weight around 65kg.
For aquariums with a length of over 70-100 cm, it is imperative that the base be provided with support beams under the center of the aquarium, because it is possible over time the plane to sag and bottom of the aquarium to burst.
Here are a few examples that may help you in choosing the aquarium. This is a small table of different aquarium models, their approximate volume, the equipment that is included with them and what kind of fish would be appropriate.
