An aquaponics fish tank is a self-sustaining system that combines aquaculture (fish farming) and hydroponics (plant growing) in one closed-loop environment. The fish produce waste which is then converted by bacteria into nutrients for the plants to grow. In turn, the plants filter the water, which is then returned to the fish tank.
Materials Needed
To build an aquaponics fish tank, you’ll need the following materials:
Aquarium tank
Aquarium pump and tubing
Fish tank filter
Fish food
Aquarium gravel or pebbles
Hydroponic grow bed
Grow media (e.g. clay pellets, coconut coir, etc.)
Plants
Water test kit
Steps to Build an Aquaponics Fish Tank
Follow these steps to build your own aquaponics fish tank:
Choose the location for your fish tank. It should be near an electrical outlet and not in direct sunlight.
Set up the fish tank and fill it with water. Add aquarium gravel or pebbles to the bottom of the tank.
Install the fish tank filter and pump. The filter will help keep the water clean and the pump will circulate water from the fish tank to the grow bed.
Place the hydroponic grow bed above the fish tank. Connect the tubing from the pump to the grow bed.
Add grow media to the hydroponic grow bed. This will provide a growing medium for the plants and help filter the water.
Add plants to the hydroponic grow bed. Choose plants that are suitable for growing in water such as lettuce, herbs or strawberries.
Add fish to the fish tank. Choose fish that are hardy and can live in a small space. Goldfish or tilapia are good choices for beginners.
Feed the fish regularly. The fish waste will provide nutrients for the plants to grow.
Test the water regularly to ensure that the pH and nutrient levels are correct for your plants and fish.
Building an aquaponics fish tank is a fun and sustainable way to grow your own food at home. By following these steps and maintaining your system, you can enjoy fresh fish and vegetables all year round!
