Setting up an aquarium is an exciting way to bring a living aquatic environment into your home, office or commercial space. However, creating a successful aquarium involves much more than filling a tank with water and adding fish. Careful planning, appropriate equipment, good water quality and patience are essential for creating a healthy environment for aquatic life.
At Aquassi Ltd, we believe that a well-planned aquarium provides the foundation for healthy fish, thriving plants and an attractive display. Whether you are setting up your first community aquarium, a planted tank, a nano aquarium or a specialist aquascape, the following guide explains the key stages involved.
1. Choose the Right Aquarium
The first step is choosing an aquarium that suits your available space, experience and intended livestock.
Consider the location carefully. The aquarium should be positioned on a suitable, stable stand capable of supporting its weight when filled with water, substrate and equipment.
Avoid placing an aquarium in direct sunlight, as excessive sunlight can contribute to unwanted algae growth and temperature fluctuations.
Larger aquariums generally provide greater water volume and can be more forgiving of small changes in water chemistry. However, smaller aquariums can be excellent choices when space is limited.
Aquassi Ltd can help you choose an aquarium and design that fits your space and requirements.
2. Decide What Type of Aquarium You Want
Before buying equipment or livestock, decide what type of aquarium you want to create.
Possibilities include:
- Tropical community aquarium
- Coldwater aquarium
- Planted aquarium
- Aquascape
- Nano aquarium
- Biotope aquarium
- Blackwater aquarium
- Shrimp aquarium
- Species-specific aquarium
Your choice will influence almost every other decision, including filtration, heating, lighting, substrate, plants and livestock.
3. Choose Suitable Equipment
A basic tropical aquarium may require several essential pieces of equipment.
These can include:
- Aquarium and suitable stand
- Filter
- Aquarium heater where required
- Aquarium lighting
- Thermometer
- Water conditioner
- Substrate
- Aquarium-safe decorations or natural hardscape
- Aquarium test kits
- Fish net
- Maintenance equipment
A planted aquarium may also require additional equipment such as specialised lighting, fertilisation and CO2 injection.
Equipment should always be appropriately sized for the aquarium and its intended inhabitants.
4. Clean the Aquarium
Before adding anything to the aquarium, clean the tank carefully.
Use clean water and avoid household cleaning chemicals, detergents or soaps. Residues from cleaning products can be harmful to aquatic life.
Aquarium decorations, rocks and other materials should also be rinsed appropriately before being introduced.
Natural rocks and wood should be confirmed as suitable for aquarium use.
5. Add the Substrate
Substrate forms the foundation of the aquarium.
Depending on your setup, this could be aquarium gravel, sand or specialist planted-aquarium substrate.
If you are creating an aquascape, substrate can be shaped to create slopes and depth. Raising the substrate towards the rear of the aquarium can help create perspective.
Aquassi Ltd can help select substrate based on the type of aquarium and plants you intend to keep.
6. Create the Hardscape
If your aquarium includes rocks or driftwood, position these before filling the tank.
This is particularly important for aquascaping because the hardscape establishes the overall structure of the design.
Take time to experiment with different arrangements. Consider the focal point, viewing angle, balance and negative space.
Large rocks and heavy pieces of wood should be positioned securely to prevent movement or collapse.
7. Add Aquatic Plants
For planted aquariums, plants can be introduced once the substrate and hardscape are ready.
Different plants have different planting requirements. Some should be planted into the substrate, while plants such as certain mosses, ferns and Anubias can be attached to rocks or driftwood.
Avoid burying plants incorrectly, particularly species where the rhizome should remain exposed.
Aquassi Ltd can recommend plants based on your lighting, aquarium size, water conditions and maintenance preferences.
8. Fill the Aquarium Carefully
Once the layout is complete, begin adding water slowly.
Pouring water directly onto the substrate can disturb the aquascape and make the water cloudy. A plate, plastic bag or other suitable surface can be used to diffuse the flow while filling.
Use appropriately treated water and follow the instructions for any water conditioner being used.
9. Install and Start the Equipment
Once the aquarium is filled, install and activate the filter and heater if required.
Check that water is circulating correctly and that the heater is positioned appropriately.
Install the lighting according to the requirements of the aquarium and plants.
If using CO2, ensure the system is installed and adjusted appropriately before livestock is introduced.
10. Cycle the Aquarium
One of the most important stages of setting up a new aquarium is establishing the biological filtration system.
Fish waste and decomposing organic matter can produce ammonia, which is toxic to aquatic life. Beneficial microorganisms in the aquarium’s biological filter help process ammonia through the nitrogen cycle.
A new aquarium therefore needs time to establish this biological filtration before fish are introduced.
This process is commonly known as cycling the aquarium.
Do not rush this stage. Testing the water regularly helps you understand how the aquarium is developing.
11. Test the Water
Regular water testing is an important part of responsible aquarium keeping.
Depending on the aquarium, tests may include:
- Ammonia
- Nitrite
- Nitrate
- pH
- General hardness
- Carbonate hardness
The appropriate parameters depend on the species being kept.
Aquassi Ltd can provide advice on water testing and help you understand what your aquarium’s results mean.
12. Introduce Fish Gradually
Once the aquarium has completed its cycle and water parameters are suitable, livestock can be introduced.
Avoid adding a large number of fish at once. Gradual stocking gives the biological filtration system time to adjust to the increased waste load.
Research every species before purchasing it. Consider adult size, temperament, swimming space, water requirements and compatibility with other inhabitants.
Never choose fish solely because they look attractive.
13. Acclimate New Fish
New fish should be acclimated carefully to their new environment.
The process allows the fish to adjust gradually to differences in temperature and water chemistry.
Follow an appropriate acclimation method based on the species and the circumstances of the transfer.
Lights can be kept subdued during introduction to help reduce stress.
14. Establish a Maintenance Routine
An aquarium is a living ecosystem and requires ongoing care.
A regular maintenance routine may include:
- Water testing
- Partial water changes
- Glass cleaning
- Plant trimming
- Removing debris
- Filter maintenance
- Checking equipment
- Monitoring fish behaviour
- Checking temperature
The exact routine will depend on aquarium size, stocking levels, filtration, plants and other factors.
15. Avoid Overfeeding
Overfeeding is one of the most common problems in home aquariums.
Uneaten food breaks down and contributes to waste and deteriorating water quality.
Feed an appropriate amount for your livestock and remove excessive uneaten food where necessary.
Fish should receive a balanced diet appropriate to their species.
16. Monitor Your Aquarium
Spend time observing your aquarium.
Healthy fish should generally display normal behaviour for their species, while sudden changes such as unusual hiding, rapid breathing, loss of appetite or abnormal swimming may indicate a problem.
Plants should also be monitored for signs of nutrient deficiencies, poor growth or algae.
Early detection can make aquarium problems much easier to resolve.
