Hi there, this is Theo from the AquaLED team, I'm going to introduce you today to the basics to start your first freshwater aquarium, here we go!

To begin with, the aquarium will allow you to reproduce a miniature aquatic ecosystem directly in your house. The living creatures in your aquarium will need oxygen to live.

Operation of an aquarium

When the lights in your aquarium are on, the plants will absorb carbon dioxide which they will convert into oxygen.

The fish will release organic waste that must be recycled and filtered to avoid pollution of the aquarium water. Uneaten food and dead leaves will be assimilated by bacteria naturally present in your tank.

 

Which species to choose for your aquarium

The main criterion for choosing the species that you are going to keep in your aquarium will be the size that you choose. You will not be able to have certain species live in a nano aquarium because they will need space to live.



Be careful, some species will not be able to live together, for example, fighters, the males of this species cannot live together, so you can only have one male fighter fish in your aquarium. Be sure to get information on the different species before making your choice.

What equipment is needed to start aquarium keeping?

Nous vous avons préparé un guide complet sur la présentation des équipements nécessaires pour débuter l'aquariophilie d'eau douce que vous pourrez retrouver ici : Quels équipements sont nécessaires pour débuter l'aquariophilie (Eau douce) ?

Certains équipements seront essentiels pour la maintenance de votre aquarium, parmi eux :

  • The filter
  • The heater
  • Lighting

There is also additional equipment that will be useful in certain cases:

  • The osmosis unit
  • The fertilizer
  • The cooling unit
  • The CO2

 

What are the important water parameters for an aquarium?

Temperature

Water temperature is the most important element to consider and monitor to properly maintain your aquarium. Water that is too warm will promote the growth of bacteria and have a negative impact on the plants in your aquarium. Water that is too cold will make your fish sick. That's why we strongly recommend a regulated heater that will automatically turn off when the right temperature is reached, otherwise we strongly recommend the use of a thermometer.

To choose the right temperature for your aquarium we recommend that you find out about the species that will be living in your aquarium and choose a temperature that corresponds to their natural habitat.

Acidity (pH)

The water in your aquarium has a certain acidity which is called pH, it is a measure of the chemical activity of hydrogen ions. The pH normally varies between 3 and 8. If the water has a pH higher than 7 then it is said to be basic, if on the other hand the water has a pH lower than 7 then it is said to be acidic.

Some species of fish are accustomed to acidic water while others usually live in basic water. It is recommended for the good of your fish to recreate a pH close to the original environment so that they live in perfect conditions.

Total Hardness (GH)

The total hardness will allow you to measure the quantity of minerals present in the water. Following a test of the aquarium water, we obtain a value which is the GH or TH. The higher the value, the harder the water. The lower the value, the softer the water. For a community aquarium, the GH should be between 6 and 16°GH.

Carbonate Hardness (KH)

One of the other parameters of water is the carbonate hardness, as its name indicates, it measures the amount of carbonates and bicarbonates of calcium and magnesium present in water. Following a test of its water, we obtain a value which is the KH or TAC. The lower this value is, the more unstable the pH of the water will be and the more it will fall. The higher the value, the more stable the pH will be but the more difficult it will be to modify. For a community aquarium, the KH should be between 3° and 8°KH.

Where and how to install your aquarium?

Before choosing your aquarium, be sure to determine where you want to install your aquarium, because if you don't have much room at home, you should avoid installing a 300-liter aquarium. The size of your aquarium will also affect the number of animals you can put in it and the price.

We recommend that if you are just starting out, you start with a nano freshwater aquarium so that you can learn with a smaller size without spending a huge budget.



A filled aquarium will be quite heavy, the furniture that you will use to display your aquarium must be solid and ready to support an equipped aquarium filled with sand, rocks and especially water because all this has a weight. Anything that is wobbly, or that could tip over, should be avoided.

What we recommend is to buy a special aquarium cabinet, so that you can be sure that it will be able to support the necessary weight. If you are buying a simple piece of furniture, we recommend that you find out how much weight the piece of furniture you have chosen can bear.

Conclusion

As you will surely have understood, before starting your first aquarium, it is absolutely necessary to be well informed before launching out because that implies time, and expenses, but also a responsibility because you will have to take care of living beings.

That was Theo, I'll see you soon,
