This is your ultimate guide on how to properly set up an aquarium in your home in 10 simple steps. Includes charts, tables and photos of some really cool home aquarium ideas.
Fish tanks offer many benefits. It’s a fun project. Kids love them. They can look great in your house. You learn about marine life. It’s no surprise many households have an aquarium somewhere, whether a freestanding, built-in style or any of the other types of fish tanks you can get.
If you want to set up a fish tank, there are a few steps you must take to do it properly. It’s not quite as simple as putting everything in your tank and adding the fish straight away. This guide will talk you through the most important steps, and how long you have to wait to add fish (it’s longer than you might think!)
Step One: Plan the Tank
It’s really important that before you buy anything, you decide exactly what you want from your fish tank.
It’s probably best to look at the type of fish you want to keep first and work from there. The fish you want will determine which other fish you can keep, and more importantly the size of the tank you’ll need.
If you’re choosing a small tank, its often more tricky to squeeze everything in than it is a larger tank so you can use a piece of paper to plan out where you’re going to put everything.
Step Two: Buy All Your Equipment
Once you’ve planned on which fish you want, do some research into those species and find out what tank size you’ll need and the other equipment you’ll need for them.
Most people choose tropical freshwater fish to start with so you’ll most likely need a heater, a filter and a thermometer.
Other decorations and plants are down to personal preference.
Step Three: Clean the Tank
If the tank is new, you’ll just need to run a damp cloth over it to remove any dust that has built up while it’s been stored.
If you’ve bought a used tank you should use warm water and white vinegar to clean the tank.
Always have a set of rags and a bucket that are new and only used for the tank. Never use household products on any of your fish equipment.
Here’s how much of a difference cleaning the fish tank can make:

Step Four: Clean the Substrate and Decorations
Substrate is the material that sits on the bottom of the aquarium.
Most substrates are quite dusty so will also need washing.
The easiest way to do this is to empty the substrate into a bucket, and keep running water over it until the water is running mostly clearly.
You can do the same with any decorations you’ve bought.
Step Five: Add the Substrate
It’s important to have the tank in position before you start filling it because the weight rapidly increases once the water is in, and it becomes tricky to move about.
Once everything is clean it’s time to get your tank in position and fill it with substrate.
Most people choose to have one or two inches of substrate, again, this will depend on the species of fish you want to keep. Some prefer a finer deeper substrate, others prefer a shallow coarse substrate.
Here’s a photo of an aquarium with the substrate added to the bottom:
How much substrate do you need in your aquarium?
It depends on the size of your fish tank. Here’s a chart setting out how much substrate to put into your aquarium based on gallon size:
Step Six: Add the Water
This step is really simple: add the water to your tank. Keep count of how many gallons of water you’ve added so you know how much de-chlorinator to add once you’ve finished.
To stop your substrate from being disturbed, you can place a saucer or bowl directly onto the substrate and tip the water into the bowl/saucer.

Step Seven: Install the Equipment
Now that the tank is full of tank, it’s time to install the equipment. Most filters and heaters are really simple to fit, just follow the instructions on the pack.
Always make sure any electrical components are installed properly before turning them on at the power supply.
Here’s an illustration of a fish tank with a regular filter:
Here’s an example of an aquarium with an under-gravel filter:
Step Eight: Add Plants and Decorations
This is where it starts getting fun! All the nitty gritty stuff is done, and you can start bringing your tank to life.
You could add freshwater plants which will help to oxygenate your water, or you might want to take the easier option and just have artificial plants.
You can also add stones, driftwood and caves, or there are a whole host of plastic ornaments available in pet stores.
Step Nine: Cycle the Tank
This is the step that most people skip completely. It’s really important to cycle your tank properly to establish good bacteria bed which will convert the fish’s ammonia into less harmful compounds.
This process normally takes around 4-6 weeks. You can buy kits to test your ammonia, nitrites and nitrate levels in the take.
You’ll notice that the ammonia and nitrite levels should spike and come back down; this is a good indication that your tank is fully cycled.
Step Ten: Add the Fish
Your tank is now complete, and while it can be tempting to add all your fish at once – don’t!
Just choose a few fish at a time to add, and try to choose hardy fish like guppies.
It’s important not to overstock your tank; there are plenty of calculators available online to check your stock levels.
Add your fish in small groups over the next few weeks until you have your desired stocking level.
