Setting up Aquaponics in Your Koi Pond

If you have a beautiful garden at home and a Koi pond to go with it, setting up an aquaponics system is the ideal way of bringing together the two practices and making the most of available resources. Kitchen gardens are an excellent hobby for those who like to grow their own vegetables. Keeping a Koi pond is recommended because it not only adds to the beauty of the garden, but also allows one to set up a small ecological system within the boundaries of the home. Here is how to set up the aquaponics in your Koi pond.

Required Materials:

  • Large garden hose
  • Bird wire
  • Extension cable (10 meters)
  • Grow tub (150 liters)
  • Pond bin (250 liters)
  • Pond pump (1000 liters per hour)
  • Fine gravel (50 kilograms)
  • Tomato plants
  • Roof tiles
  • Bricks
  • Digital timer
  • Air pump with two outlets
  • 6 Koi fish

Step 1: Digging for the Fish Tub

Digging a hole for the fish tub has to be done very carefully, since it is important to ensure that the pond will receive some shade so that the water does not evaporate. Also, the tub must be placed a little lower than the ground surface so that the water remains at an even temperature.

Step 2: Placing the Extension Cable and Connecting Pumps

The waterproof extension cable has to be placed from a secure electric source (for example, in a shed) near the pond. The water pump and air pump have to be attached to the electric supply outlet. Make sure that all electrical materials and leads are safely stored in a waterproof box away from this system.

Step 3: Drilling

Drill holes at the base of the grow tub. This is needed for the water to be able to flow backward into the fish tub. Next, place the fish tub in close proximity of the grow tub so that the water pump does not get strained in pumping water between the two tubs.

Step 4: Connecting Hoses

Take a hose and affix it to the 1000 liter pond pump, and then run it to the grow tub as well. The digital timer has to be set up at this stage and fixed according to the cycle one wants to follow. The timer will ensure that the pond pump switches on and off as needed without fail.

Step 5: Filling the Tub

Pour water into the fish tub that does not have chlorine traces and put the fish in. Start the system to see if the water is passing between the fish tub and the grow tub and back again as it should. Note the speed of the water passage, as this will reduce to a great extent once the gravel is added for the garden growth.

Step 6: Adding the Gravel

Ensure that the gravel has been washed and cleansed thoroughly before piling it into the grow tub. The next step is to add seeds or transplanted growing plants to the gravel. Wait patiently for the germination to occur.
