Set Up Your First Aquarium Step by Step

An aquarium begins with the proper execution of a few critical tasks. Discover what those tasks are and how to accomplish them using this beginner's guide.

  1. Choose and Plan Your AquariumBefore purchasing the fish, make sure you choose an appropriate aquarium size according to your space and budget. It is necessary to consider a number of factors, including tank size, filtration, heating, lighting, substrate, and types of fish you want to keep.
  2. Setup and Cycling the AquariumSet up all the equipment, fill the tank with treated water, and let it cycle before adding any fish. The cycling allows to establish beneficial bacterial colonies inside the filter and makes it possible for the aquarium to break down the fish waste.
  3. Choose Compatible FishSome fish cannot be kept together because of different reasons. Before purchasing fish, you should research their adult sizes, temperaments, temperatures, water requirements, and schooling habits.
  4. Create a Simple Maintenance ScheduleThe maintenance of an aquarium requires some work, but it should not be complicated. Make sure you are checking your fish and equipment every day and testing the water parameters as required and performing partial water changes regularly.

Quick answers

Common Aquarium Questions Answered Simply

How do I cycle my new aquarium before introducing fish?

Start your aquarium, turn on the filter and heater, and cycle your tank with beneficial bacteria before introducing any fish. While doing this, test your water for ammonia, nitrite, and nitrates. When both ammonia and nitrite levels reach zero, then your tank is cycled and you can introduce the fish.

How often do I need to change my aquarium water?

The frequency of changing water in the aquarium is a common practice, but it will depend on the size of the aquarium, fish load, feeding, and water tests that you have to perform. Do not change all the water in one go because it will imbalance the aquarium and stress the fish.

Which water parameters should I check in a freshwater aquarium?

In a freshwater aquarium, the first parameters that should be checked are ammonia, nitrite, nitrate, temperature, and pH. There might be some specific needs for certain species of fish regarding water hardness or alkalinity.

What things must be considered before purchasing my first fish?

Ensure that the aquarium is cycled and spacious enough to accommodate the fish. Look into the size of the fish when it reaches adulthood, temperature, pH requirements, nature, feeding habits, and whether it requires other fish to cohabit.

Do I need to change all the filter media of my aquarium at once?

No, do not do so. The filter media have beneficial bacteria, which make it safe for the fish to live in the tank. Changing all of it may result in loss of such beneficial bacteria and impact the water quality of the tank.

Tank Calculator

Calculate Your Aquarium Water Volume

Calculate the volume of your aquarium to determine how much water it contains. Determining the capacity of your aquarium will assist you in selecting appropriate fish, the proper dosage of water conditioners, and a proper maintenance schedule.

To obtain the most accurate figure, you will need to take the measurements of the inner length, width, and water depth of the aquarium. Do not forget that decorations, gravel, and plants will take up some space in the aquarium.
