Raising fish in your own backyard is an excellent and sustainable method of feeding your family. An abandoned swimming pool can serve as the perfect avenue for this pursuit. Converting your pool to raise fish takes many months of water monitoring and conditioning before it is safe to introduce hatchlings, but is not all that labour intensive. With patience, the right instructions and equipment you'll be able to raise fish in your swimming pool and serve a product to your family of which you can be proud.

  1. 1

    Complete drain the pool if it is not drained already to get rid of the chemical-laden pool water. Completely fill the pool with fresh water.

  2. 2

    Add the appropriate amount of chlorine detox, based on your pool size, to the fresh water in order to eliminate any traces of chlorine and neutralise heavy metals.

  3. 3

    Turn on your pool pump to allow filtration and circulation to evenly distribute the new chemicals in your pool. Allow the pool water to filter and circulate for a few days before proceeding to step four.

  4. 4

    Add the appropriate amount of pond bacteria, based on your pool size, to provide your future fish with heavily oxygenated water. Allow the pool water to filter and circulate for a few days before proceeding to step five.

  5. 5

    Test the water's PH level (which should read between 6.8 and 7.8), ammonia level (which should read between zero and one), and nitrate level (which should read less than five pmm) using the water testing kit. Adjust the chemicals accordingly by adding PH up or down to regulate the PH level, adding more pond bacteria to lower the ammonia level and adding salt to lower the nitrate level (50mg/gallon of water). Allow the pool water to filter for a week before proceeding to the next step.

  6. 6

    Test the water again using the water testing kit and adjust if necessary. Add several goldfish to the water. Consider these fish to be disposable as they will be testing the water to ensure it's safe to add larger fish.

  7. 7

    Choose a fish you would like to raise in your converted pool that's appropriate to your environment. Introduce the chosen fish to your pool if the goldfish have survived for at least two weeks.

  8. 8

    Test the water every week and adjust the chemistry whenever necessary. Monitor the fish and feed them on a regular basis.

Tips and warnings

  • To maintain this set-up you will need to skim the surface of the pool with a standard pool net to keep it clean.
  • Keep your regular pool pump and filter running frequently to keep the water circulating, which will help to keep the water properly balanced and clean.
  • It's a good idea to backwash your filter at least once a week to keep your pool filter clean.
  • Vacuum your pool often to remove solid fish waste, which will help keep the pool's environment fish-friendly and decrease the chances of spreading disease.
  • Tilapia or Catfish are most popular to raise in swimming pools due to their ability to handle cool water conditions, little maintenance and rapid maturity cycles.
