Create a balanced aquarium is essential to ensure the health of your fish and maintain a healthy ecosystem in the long term. This requires careful planning and special attention to detail so that water, plants and fish live together harmoniously. Here are the steps to be taken to successfully set up and maintain a balanced aquarium.
1. Choose the right location and size of aquarium
Before you start installing your aquarium, it is important to choose well Location and Size of this one.
Tips for choosing the location:
- Avoid direct sunlight : Direct exposure to the sun can lead to excessive algal blooms and changes in water temperature. Choose a place away from direct sunlight.
- Stable surface area and level : Make sure that the aquarium is placed on a stable and well level surface to avoid long-term leaks or cracks.
- Close to an electrical outlet : Your aquarium will need electrical equipment such as filters, pumps and lighting. Place it close to an electrical outlet to facilitate installation.
Aquarium size:
- The bigger the better : A larger aquarium (minimum 40 to 50 litres) is often easier to balance than a small aquarium, as variations in parameters (such as temperature and water quality) are less sudden.
- Adapt size to your fish Choose an aquarium adapted to the size and number of fish you want to place there. Too small a space can cause stress and disease in fish.
2. Prepare and install substrate
The substrate is the basis of your aquarium and is an essential element for ecosystem balance. It influences plant growth and biological filtration.
Types of substrate:
- Sand or gravel : Gravel is often used because it is easier to clean, but sand can also be chosen for certain types of fish (such as catfish) that like to search the substrate.
- Nutrient substrate : If you plan to plant aquatic plants, choose a nutrient substrate which promotes their growth by providing the necessary nutrients.
How to install:
- Rinse the substrate before adding to the aquarium to remove impurities.
- Have a layer of nutrient substrate at the bottom (if used), then a layer of gravel or sand above.
- The substrate layer must be 3 to 5 cm thick to allow good rooting of the plants.
3. Install filtration system
The filter is one of the most important elements to maintain a balanced aquarium. He assures the mechanical filtration, Chemical and organic Water.
Types of filtration:
- Mechanical filtration : Eliminates suspended debris and particles in water.
- Chemical filtration : Uses materials such as activated charcoal to remove toxins, odours and chemical impurities.
- Biological filtration : Allows the colonization of beneficial bacteria that degrade ammonia and nitrites, compounds toxic to fish.
Installation and maintenance:
- Install a filter adapted to the size of your aquarium (check the recommended flow rate for your tank volume).
- Clean the filter regularly without using tap water to avoid killing beneficial bacteria. Use aquarium water when changing water to rinse the filter elements.
4. Install heating and lighting
The heating andlighting play a crucial role in the stability of your aquarium and in the health of fish and plants.
Heating:
- Temperature adapted to fish : Most tropical fish require a temperature of 24-28 °C. Use a heating with thermostat to maintain a constant temperature.
- Regularly control the temperature with a thermometer to make sure it stays stable.
Lighting:
- Plant lighting : Aquatic plants require quality lighting to achieve photosynthesis. Use lighting adapted to the depth of the aquarium and your plants (8-12 hours of lighting per day).
- Avoid excessive light : Excessive lighting can cause algal bloom. Adjust the luminous intensity and duration according to the specific needs of your ecosystem.
5. Add aquatic plants
The aquatic plants play a key role in the balance of your aquarium. They contribute to water oxygenation, absorb nitrates and provide a natural refuge for fish.
Benefits of Aquatic Plants:
- Improve water quality : Plants absorb excess nutrients (such as nitrates) and help limit algal bloom.
- Bring oxygen : Through photosynthesis, plants release oxygen into the water, essential for fish.
- Natural balance : They mimic the natural habitat of fish, offering hiding places and reducing stress.
Choose the right plants:
- Fast-growing plants : Plants like the ceratophyllum or vallisneria quickly absorb nutrients and help control algae.
- Robust plants : If you're new, opt for easy maintenance plants such as anubias, the Java fern or Java foam.
6. Wait for the nitrogen cycle before adding fish
One of the common mistakes when installing a new aquarium is adding fish too quickly. It is important to let the aquarium go through the nitrogen cycle, a process that allows ammonia to be broken down into nitrites, then nitrates, which are less toxic to fish.
The nitrogen cycle:
- Starting phase : In the first few weeks after aquarium installation, beneficial bacteria begin to colonize the filter and substrate. These bacteria transform ammonia (from fish waste) into nitrites, then nitrates.
- Water tests Use test kits to monitor ammonia, nitrite and nitrate levels. Wait until ammonia and nitrite levels are zero before introducing fish.
- Wait time : It can take between 4 and 6 weeks. Be patient and introduce your fish gradually to avoid overloading the biological system.
7. Introduce fish gradually
Once your aquarium is cycled, you can start introduce fish. But this step must be done carefully to avoid an imbalance in the ecosystem.
How to introduce fish:
- Add fish in small groups : Enter a small number of fish at a time (1 to 3 fish), then wait a week before adding more. This allows filter bacteria to adapt to the new biological load.
- Avoid overpopulation : An overcrowded aquarium is more difficult to balance. Respect the general rule of 1 cm of fish per litre of water (taking into account the adult size of fish).
- Acclimatization : Before releasing the fish into the aquarium, let them acclimatize to water temperature and parameters. Place the bag containing the fish in the water for about 20 minutes, then gradually add water from the aquarium into the bag before releasing them.
8. Maintaining the aquarium regularly
Once your aquarium is in place, its regular maintenance is essential to maintaining a healthy ecosystem.
Maintenance tasks:
- Change water regularly : Change about 10 to 20% of water each week to maintain water quality.
- Window cleaning : Use an algae cleaner to keep aquarium walls clean.
- Check water parameters Regularly test pH, ammonia, nitrites and nitrates to ensure that everything is in balance.
- Cut plants : If your aquatic plants grow quickly, cut them regularly to prevent them from invading the aquarium.
Summary table of steps for a balanced aquarium
| Step | Actions |
|---|---|
| Choice of location and size | Location away from direct sun, aquarium of at least 40 liters |
| Installation of substrate | Nutrient substrate, sand or gravel (3-5 cm thick) |
| Filter system | Mechanical, biological and chemical filtration adapted |
| Heating and lighting | Maintain temperature and lighting suitable for fish/plants |
| Adding aquatic plants | Fast growing plants, easy to maintain |
