Here are the steps to set up an aquarium.
1. Understand the Different Types of Aquariums
There are several types of aquariums that you can build. Each of them caters to the specific needs and preferences of certain fish species.
Here is a list of some common types of aquariums:
- Freshwater Aquariums: These are the most popular type of aquariums, housing freshwater fish and plants. They are further divided into:
- Tropical Freshwater Aquariums: For fish from tropical climates, requiring warmer water temperatures.
- Coldwater Freshwater Aquariums: For fish from colder climates, requiring cooler water temperatures.
- Saltwater Aquariums: Also known as marine aquariums, these house saltwater fish and other marine life. There are two main types of saltwater aquariums:
- Fish-Only Saltwater Aquariums: These focus on saltwater fish species without live corals or other invertebrates.
- Fish-only With Live Rock (FOWLR) Saltwater Aquariums: These aquariums focus on saltwater fish species and include live rock for biological filtration and natural aesthetics, but don’t contain live corals or other invertebrates.
- Reef Tanks: These are designed to mimic the natural coral reef ecosystem, including live corals, fish, and invertebrates.
- Brackish Aquariums: These aquariums have a mix of freshwater and saltwater, creating a unique environment for brackish water fish species like pufferfish, scats, archerfish, etc.

Once you have finalized the place for your aquarium, measure its dimensions to get an idea about the tank size you can accommodate in that space.
Also, take note of any furniture or structures that will support your aquarium. Ensure they’re sturdy enough to handle the weight of the aquarium tank filled with water and decorations.
3. Choose the Fish Species to Keep in The Aquarium
Choosing the right fish for your aquarium requires careful consideration of several factors.
Here are some guidelines to help you make the best choice:
- Aquarium size: Choose fish that will thrive in the size of your aquarium. Some fish need more swimming space, while others can live comfortably in smaller tanks. Keep in mind that a larger tank is usually more stable and easier to maintain.
- Compatibility: Research the compatibility of the various fish species that you plan to keep. Consider temperament, size, and any specific requirements each species may have. Avoid mixing aggressive or territorial fish with peaceful, community-oriented species.
- Water parameters: Different fish have specific water parameter requirements, such as temperature, pH, and hardness. Choose fish that can thrive in the same water conditions to ensure their health and well-being.
- Diet: Be aware of the dietary needs of the fish you choose. Some fish are herbivores, others carnivores, and some omnivores. You will have to provide a balanced diet appropriate for each species in your aquarium.
- Care level: Some fish are easier to care for than others, making them better suited for beginners. Research the care level of each species you’re considering and choose fish that match your experience and ability to provide proper care.
- Aquarium setup: Consider the type of environment your fish will need to thrive. Some species prefer densely planted tanks, while others need hiding spots provided by rocks or decorations. You will need to tailor your aquarium setup to the needs of your chosen fish.
- Growth potential: Be aware of how large your fish will grow when fully mature. Overcrowding can cause stress and health issues, so make sure your aquarium can accommodate the adult size of each species.
- Schooling vs. Solitary fish: Some fish prefer to live in groups or schools, while others are more solitary. Choose fish that can fit into your aquarium, and make sure to keep schooling fish in appropriate numbers for their social well-being.
- Availability: Check the availability of your desired fish species at local pet stores or online retailers. Some fish are challenging to find, so consider alternative options if necessary.
By taking these factors into account, you’ll be better prepared to select fish that will thrive in your aquarium.
4. Get the Necessary Aquarium Equipment
Start by getting an appropriate aquarium filter based on your tank size and the type of fish you plan to keep.
Filters are crucial for maintaining water quality as they remove harmful chemicals, excess food, and waste from the water.
Read out guide on aquarium filters to know everything about them.
Aquarium heaters are also important, especially for tropical fish that need warmer temperatures.
Make sure to get an aquarium thermometer as well so you can monitor and maintain the ideal water temperature range in your fish tank.
Here’s everything you should know about aquarium heaters and aquarium thermometers.
Next, consider what type of substrate you want in your aquarium – gravel, sand, soil, etc.
This will not only enhance the appearance of your aquarium but also provide a suitable environment for beneficial bacteria growth and support any live plants you may add later on.
Also, choose decorations like rocks, driftwood, and plants that complement your desired theme while providing hiding spots for your aquatic inhabitants.
Don’t forget about aquarium lighting too which is essential for both viewing pleasure as well as for plant growth if you have live plants in your tank.
You will also need an air pump and air stone to help oxygenate the water, although this is optional depending on your specific aquarium setup.
Make sure to also pick up a water conditioner to neutralize the chlorine found in tap water (which can be harmful) along with fish food suited for the fish you want to keep.
Some fish species tend to jump out of the tank. So you will have to get an aquarium lid (or hood) if you plan to keep such fish species.
Moreover, to ensure proper maintenance of your aquarium over time, invest in an aquarium test kit – this will help identify potential issues before they become serious problems.
You should also get a gravel vacuum (for cleaning) and a net (for safely moving or removing your fish while cleaning the aquarium).
5. Clean the Aquarium Tank and Equipment
Now that you’ve got everything to build your aquarium, it’s time to give your aquarium tank and its components a thorough cleaning.
Begin by rinsing the inside and outside of the aquarium tank with clean water, making sure not to use any soap or chemicals as they can be harmful to fish.
Gently scrub the tank glass with a soft cloth or sponge to remove any dust or debris.
Don’t forget to clean the aquarium hood, light fixtures, and other parts that may have come in contact with dirt during storage or transport.
Next, focus on cleaning the substrate, decorations, and plants.
Place the substrate in a bucket and repeatedly rinse it with clean water until the water runs clear; this will help remove any lingering dust or contaminants.
For decorations like rocks, caves, and ornaments, give them a good rinse under running water while lightly scrubbing away any visible dirt with a soft brush.
Artificial plants should also be rinsed thoroughly under running water; if they’re particularly dirty or covered in algae from previous use. You can gently scrub them using an old toothbrush.
Remember that cleanliness is crucial when setting up an aquarium because even small amounts of dirt can negatively affect water quality and potentially harm your fish once they’re introduced into their new home.
6. Add Substrate and Decorations to The Aquarium
Start by pouring a 1 to 2-inch layer of the cleaned substrate evenly across the bottom of your aquarium.
The substrate serves as both a foundation for your aquatic plants and a home for beneficial bacteria. So it’s important to choose one that suits your needs, such as gravel or sand.
Now let’s focus on decorating your aquarium.
Keep these three key tips in mind when placing rocks, driftwood, and other decorations:
- Create hiding places: Fish love having nooks and crannies where they can retreat from prying eyes. Make sure there are enough hiding spots throughout the tank to accommodate all of its future inhabitants.
- Consider visual interest: Arrange objects at different heights and angles to create depth and variety in the layout. This will not only make the tank more attractive but also help simulate a natural environment for your fish.
- Plant live plants (optional): If you’re using live plants, gently push their roots into the substrate while avoiding damage to their delicate root systems. Plants not only add beauty but also provide shelter for fish and oxygenate the water.

7. Install the Aquarium Equipment
First, set up your filter by following the manufacturer’s instructions and place it at one end of the aquarium or under the gravel.
This will ensure optimal water circulation for a healthy environment.
Next, you’ll need to install the heater and thermometer close to each other for accurate temperature readings.
This combination is crucial in maintaining a stable water temperature that suits your fish species.
Now, if you’re using an air pump and air stone, attach them together and position the air stone inside the aquarium.
This will help oxygenate the water and provide better living conditions for your fish.
Lastly, set up your lighting system according to its manufacturer’s directions; usually placed on top of the aquarium or using a designated mounting system.
With these steps completed, you’ve successfully installed all the necessary equipment to create a thriving aquarium.
|Filter||One end of the aquarium or under the gravel||Water circulation|
|Heater||Close to thermometer||Temperature control|
|Thermometer||Close to heater||Temperature monitoring|
|Air Pump & Air Stone||Inside the aquarium||Oxygenation|
|Lighting System||On top or on mounted system||Illumination|
8. Fill the Aquarium with Water
Fill up a clean bucket with tap water (or another water source suitable for your aquarium type).
Then, place a clean plate or bowl on top of the substrate to prevent the water from displacing it.
Slowly pour the water onto the plate or bowl, allowing it to overflow gently into the tank. Use a hose or bucket with a pour spout to add the water into the tank.
This helps protect your aquascape from getting disturbed by the force of the water.
Be patient and take your time while filling up your tank until it’s about 1 inch from the top.
9. Add Water Conditioner to The Aquarium Water
A water conditioner neutralizes harmful chemicals like chlorine, chloramine, and heavy metals that are usually found in water.
These chemicals can cause stress and even be fatal to your fish if not treated properly.
To add the water conditioner to the water, first calculate the volume of your aquarium tank and then follow the instructions on the bottle.
Here’s a quick guide on calculating the volume of common aquarium tank sizes:
|Aquarium Size (gallons)||Length (inches)||Width (inches)||Height (inches)|
To find your aquarium tank’s volume in gallons, multiply its length, width, and height (in inches), then divide by 231.
For example, if you have a standard-sized 10-gallon tank with dimensions of 20x10x12 (LxWxH) inches:
Aquarium Tank Volume = (20 x10 x12)/231 ≈ 10 gallons
Once you’ve calculated your tank’s volume, carefully read the instructions on the water conditioner bottle to determine how much amount you should use for that specific volume.
Then, add the specified amount of water conditioner to the aquarium water.
10. Turn on The Aquarium Equipment and Adjust the Settings
First, plug in and turn on the filter, heater, air pump, and lighting. These devices are essential for maintaining a stable environment within your aquarium.
Make sure that all cords are safely placed away from water sources to avoid any accidents. Keep an eye on each device as you switch it on to ensure they’re operating correctly.
Now it’s time to adjust the settings.
Start with the heater; set it to the appropriate temperature for your specific fish species (typically around 76°F to 80°F or 24°C to 27°C for tropical fish).
Use a thermometer to monitor the water temperature over the next few hours. Adjust the heater until you reach a stable level.
Don’t forget to adjust other equipment such as lighting schedules (if applicable) or your air pump’s flow rate based on your aquarium setup and inhabitants’ needs.
It may take some trial and error before everything is just right, but taking these steps will help create a comfortable environment where your aquatic pets can thrive.
11. Cycle the Aquarium Tank
To begin this process, you’ll need to introduce ammonia into your tank by adding a small amount of fish food.
This will jumpstart the growth of beneficial bacteria that break down toxic waste products like ammonia and nitrite.
Make sure to keep an eye on the temperature, pH levels, and filtration during this time as well.
Throughout the cycling period, which typically takes 2 to 4 weeks, it’s essential to test your aquarium water regularly for ammonia, nitrite, and nitrate levels.
You’ll notice changes in these parameters as the beneficial bacteria establish themselves and work their magic within your tank.
Once both ammonia and nitrite levels reach zero while nitrates are present at acceptable levels (ideally below 20 ppm), congratulations – you’ve successfully cycled your aquarium!
12. Buy and Add Fish to The Aquarium
When buying fish for your aquarium, it’s essential to select healthy specimens that are compatible with the size of your tank and its specific conditions.
Always buy fish from a reputed store or someone you know very well.
Once you have bought the fish, gradually introduce them into the tank so as not to overwhelm the biological balance of your aquarium.
Remember to avoid overcrowding or introducing aggressive species that may disrupt the balance of your carefully cultivated ecosystem.
Acclimating your new fish is also crucial to ensuring their well-being as they adjust from store-bought conditions to their new environment.
Start by floating the sealed bag containing the fish in your aquarium for 15 to 20 minutes – this helps equalize temperatures between the water in the bag and in the tank.
Next, open up the bag and gradually mix small amounts of aquarium water into it over a period of 15 to 20 minutes; this gives the fish time to adapt safely to any differences in water chemistry.
Finally, use a net to gently transfer each fish from the temporary holding bag into its permanent aquatic residence.
Take care not to introduce any potentially contaminated water from the bag into your pristine tank setup.
13. Monitor and Maintain the Aquarium
Now that your fish are acclimated, it’s vital to keep a close eye on their new environment and consistently maintain optimal conditions for their health and well-being.
Make sure the water temperature remains within the appropriate range for the specific species in your tank.
Check your heater and thermometer daily to ensure they’re functioning correctly.
Regularly inspect all other equipment, such as filters, lights, and air pumps, to confirm they’re running efficiently.
If you notice any issues or malfunctions with your equipment, address them promptly to prevent harm to your aquatic pets.
In addition to checking the temperature and equipment, test the water quality frequently using an aquarium test kit.
Measure essential parameters like pH levels, ammonia, nitrite, and nitrate concentrations at least once a week – imbalances can lead to stress or illness in your fish.
Perform partial water changes (about 20-30%) every two weeks or as needed based on test results; this helps maintain healthy water chemistry while removing waste products from the tank.
Keep an eye on algae growth as well; excessive amounts can be harmful to fish and plants alike. Use an algae scraper or magnetic cleaner to remove buildup from glass surfaces regularly.
By diligently monitoring and maintaining these aspects of your aquarium environment, you’ll ensure a safe and thriving habitat for your underwater friends.
Always Keep This in Mind…
Setting up an aquarium may seem daunting at first, but with careful planning and attention to detail, you’ll create a thriving aquatic environment for your fish.
Remember to choose the right size and location, purchase the necessary equipment, and follow proper cycling procedures before adding your fish.
Keep monitoring and maintaining your aquarium’s conditions to ensure its success. With dedication and patience, you’ll soon have a beautiful underwater world for everyone to enjoy.
