Aquaponics System Basics: Introduction to the fundamental concepts of aquaponics

What is Aquaponics?

Well, this close cousin of hydroponics is a great concept! imagine a garden that practically takes care of itself. No more soil to till, no more weeds to pull, and no more back-breaking labor. Intrigued? Welcome to the world of aquaponics! In essence, aquaponics combines aquaculture (raising aquatic animals such as fish) and hydroponics (growing plants without soil) into a symbiotic environment. I love the idea of the integration & harmony that can exist in Aquaponics systems. This article on Aquaponics System Basics will have you brimming with excitement as far as what’s possible & how incredibly sustainable & rewarding this can be!

The Magic of Aquaponics

Untitled design 47

In a nutshell, fish produce waste, and this waste becomes a natural food source ie. nutrients for the plants. The plants, in turn, filter and clean the water for the fish. It’s an incredible cycle of life, all happening right before your eyes! Amazing!

Components of an Aquaponics System Basics

The Fish Tank

This is the heart of the system. It’s where your fish live, eat, and produce waste that kickstarts the entire process.

Best Fish for Aquaponics

When starting out, hearty, tolerant fish like tilapia or goldfish make excellent choices. They’re resilient, adaptable, and produce a healthy amount of waste for your plants to munch on.

The Grow Bed

This is where your plants reside, happily absorbing the nutrient-rich water that flows from the fish tank.

Best Plants for Aquaponics

You can grow a diverse range of plants in an aquaponics system. Leafy greens like lettuce and spinach thrive in this environment, as do herbs like basil and mint.

The Biofilter

This is the unsung hero of your system. It houses the beneficial bacteria that convert fish waste into plant food. Without a good biofilter, the magic of aquaponics simply wouldn’t happen.

Benefits of Aquaponics


Aquaponics uses significantly less water than traditional farming, making it a top choice for sustainable gardening. And the best part? It’s organic, too!


Aquaponics systems can be set up virtually anywhere, from your backyard to your basement. They require less space than traditional gardens, yet yield more produce.

Health and Taste

Plants grown in an aquaponics system are often healthier and tastier. They’re free of pesticides and fertilizers, and they absorb the rich nutrients produced by the fish, giving them a robust flavor.

Setting Up Your Own Aquaponics System

Choose Your Location

Your system can be indoor or outdoor, but it needs a consistent temperature, good air circulation, and access to sunlight or grow lights.

Choose a system

There are small ready made systems suitable for indoors that are an excellent way to get started & get a feel for aquaponics. They eliminate the need to source all the correct components increasing the chance of success & saving time. They also look attractive & can be a great conversation topic in your home – Check out these examples; click on the images to find out more!

Assemble Your System

Setting up your aquaponics system can be a fun weekend project. You’ll need a fish tank, a grow bed, a biofilter, and of course, fish and plants.

Maintenance and Troubleshooting

Keep an eye on your water’s pH level and temperature, and monitor your fish and plants for signs of stress or disease. Remember, an ounce of prevention is worth a pound of cure!


With an aquaponics system, you get the joy of raising fish and the satisfaction of growing your own food. It’s a win-win situation. So why not give aquaponics a try?
