Building a Mini Aquaponics System

What You'll Need
Glass or plastic fish tank or container and accessories
Water thermometer (especially for tropical fish)
Aquarium test kit to check ammonia, pH, nitrate, and nitrite level
Small aquarium water pump
Plastic tubing to fit water pump
Gravel 2.5 lbs for every 5 gallons
Air pump, air stone and tubing to connect both
Grow bed

The aquaponics system is a technique to raise fish and plants hydroponically. To build a mini aquaponic system at home, follow the steps mentioned in this article.


  • Set up the fish tank according to the instructions in the manufacturer’s booklet. The fish tank can be plastic, glass, or any container that can carry water. Anything that can carry 5 to 20 gallons of water would work. If you want to have a larger tank, make sure you have the space. After all, the larger the tank, the larger the bed area required.

  • Get a drill machine a drill 1/8inch holes in the bottom of the grow bed at equivalent distances to allow water to drain into the tank. In the back corner, drill a hold for the tubing from the water pump.  

  • Fill the tank bottom with gravel. This gravel acts like nitrifying bacteria that converts ammonia to nitrite and then to nitrate. This gravel comes in all shapes, sizes, and colors. It is important to wash and clean the gravel pebbles with soap and water, as they tend to carry a lot of dust with them.

  • A deep plastic container that would act like the grow bed is necessary. The plants would grow in this container, which would sit on top of the tube.

  • Place the water pump to allow the water to be pumped in the grow bed. Use an air pump to blow air into the tank for both the plants and the fish. This can be done be using the tubing. The tubing would connect the air pump to an air stone that would rest at the bottom of the tank. The air stone helps create oxygen in the water through bubbles that come from the air pump.

  • Check the pH level with the help of a litmus paper. The idea pH level must be 7.0. In addition to this, check the nitrite, ammonia, and nitrate levels.

  • Leave the fish in its new home after the tank is set for 24 hours. In the beginning, stock very little fish. However, after a month, add more.

  • Add the plants after about four weeks.
