Tips for Setting Up An Aquarium as A Hobby
If you’re into fish or aquariums, you’ve probably thought about setting up your own tank at some point.

But figuring out where to start can be complicated. This guide will help you avoid common mistakes and set up a successful aquarium, even if it’s for fun or business.
Let’s look at the step-by-step guide to get you started and tips on how often to clean your tank.
How to Set Up an Aquarium as a Hobby
An aquarium is basically a glass tank where fish live and can be easily observed. It’s like a little underwater world that you can enjoy watching every day.
But before jumping in, planning is key. Decide on the size of the tank and where you want to place it.
Once you’ve figured that out, make sure you have all the necessary supplies. Here are the steps for setting up an aquarium;
1. Wash the Gravel
Begin by washing the gravel that you are going to use in the tank. Dirty gravel will cause your tank water to become cloudy for weeks.
Here’s how to clean it:
(i). Put the gravel in a bucket.
(ii). Take a hose and point the nozzle towards the bucket with a lot of force.
(iii). Mix the gravel around with your hands to ensure you remove any dirt or dust that may be on it.
(iv). Empty the water in the bucket and discard it but the gravel should remain.
(v). Do this several times until, the water becomes clear.
Do not panic if the water is still a little murky due to the gravel, it will clear after some time. Washing it just helps to get rid of dust from storage and transport process.
2. Add the Gravel to the Tank
Sprinkle it evenly over the bottom of your tank after you clean them. This is done carefully to avoid scratching the glass of the tank and also to avoid disturbing the fine particles.
Spread it out using your hands and make it about half an inch thick.
To add beauty to the aquarium, you can angle the gravel, so that it is higher at the rear part of the tank than at the front.
This provides the tank with a little perspective and makes it look much nicer to the eye.
3. Filling Your Aquarium
If there is no tap around, use a hose pipe or buckets to fill the tank with water. After that, add a water de-chlorinator to get rid of chlorine and other chemicals in water.
Although there is no fish yet in these structures, they can accumulate over time. For every water change, you will need a good-quality de-chlorinator.
Some of the most recommended ones are Seachem Prime, API Tap Water Conditioner, and Tetra AquaSafe.
4. Decorating Your Aquarium
Decorating your tank isn’t just fun but it makes your fish feel at home. Some fish enjoy open swimming spaces, while others prefer hiding spots.
Do research about your fishs need and decorate accordingly. When adding new fish later, introduce decorations gradually so each new fish can claim its own space.
Also, make sure to select a proper heater and filter for your tank.
5. Cleaning and Setting Up the Filter
Before using the filter, rinse the filter material (like sponges or carbon packets) under water to remove dust and debris.
Be gentle to avoid damaging it. Do the same for any rocks or ornaments you plan to add to the tank.
For hang-on filters: Fill the reservoir manually to get it started and; adjust the flow rate to maximum for the cycling process.
For canister filters: Stack the filter baskets tightly and lock the lid securely to prevent leaks.
6. Setting Up Heating and Lighting
Use one or two heaters, depending on your tank size. A higher wattage heater is generally better as it uses less energy and lasts longer.
Place the heater in an area with good water flow but where it’s not too visible. Set the temperature to 74–80°F (23–27°C), and you’ll see an orange light indicating it’s heating.
For lighting, choose a light that suits your tank and set it to be on for no more than 8 hours a day.
7. Cycling Your Tank
Cycling is a crucial step that allows beneficial bacteria to grow and create a healthy environment for your fish.
Use a freshwater test kit (like API’s Freshwater Test Kit) to monitor water conditions during the cycle. Many aquarium stores also offer water testing for a small fee.
The cycling process prevents water imbalances that can harm your fish. It’s worth the time and effort to do it properly.
8. Research Before Adding More Fish
Keep a list of the fish in your tank to ensure compatibility when shopping for new ones. Local aquarium experts can help you find species that will get along.
Tips for adding fish:
(i). Schooling fish thrive in groups of 5 or more.
(ii). Some fish prefer to live in pairs, trios, or solo.
(iii). Wait a few weeks before adding scavengers, as they need leftover food to thrive.
How Often Should I Clean my Aquarium Tank?

It takes about a fortnight to clean most aquariums but this will depend on the number of fish you have and how dirty they are.
Here’s what you should do when cleaning your tank:
1. Siphon the Gravel: Scoop the debris and any remaining food with a siphon from the gravel. You should also replace approximately 10-15% of the water.
2. Check the Filter: Check if your filter is efficient in its work.
When you maintain your aquarium properly, then your fish will be healthy. They will feed well, be safe, and will be well taken care of in a clean environment.
If you do things properly, your fish will be healthy, free from its predators, and will be able to breed.
Of course, if you are creating an aquarium for a hobby or developing a business, a properly built aquarium will help you enjoy and take care of the fish.
