How to Care for a Garden Pond

Ensuring a clean and healthy environment for the plants and fish in a garden pond requires care. Performing regular maintenance makes caring for a garden pond easier. If left unattended, the pond can quickly become a breeding ground for algae requiring extensive cleaning.

Things Needed:



  • Skimming net

  • Pond filter

  • Water pump

  • Air pump

  • Water dechlorinator

  • Pond vacuum

  • Fish

  • Water plants



  1. Skim the leaves and debris from the surface of the pond with a skimming net. Ideally, this would be performed daily, especially in the fall, but should be performed at least every other day. This is the easiest step in the care of the pond, and it will yield the greatest results in the health of the pond's ecosystem.

  2. Clean the pond with a vacuum once a month or so to prevent sludge and decomposing leaf debris from building up.

  3. Maintain a working water pump or waterfall feature. This will keep the water aerated and make the pond less attractive to insects.

  4. Supplement the aeration of the pond with an air pump during the summer when fish need more oxygen.

  5. Change or clean the pond filter regularly.

  6. Use a dechlorinator when adding water to the pond. This will break down the chemicals in the tap water making it safe for plants and fish.

  7. Add fish and snails to the garden pond. They feed on the algae in the water. Be sure to feed the fish one to two times a day, but do not overfeed. Only feed what the fish can consume in 5 minutes.

  8. Grow water plants in the pond. They will oxygenate the water and provide shelter for fish. Plants also circultate nutrients in the ecosystem. It is important to remove dead leaves and plants from the pond promptly though.
