Cotswold Koi provide a professional pond cleaning service around Oxfordshire, Gloucestershire, Wiltshire, Worcestershire and the surrounding counties.


More natural ponds or inadequately filtered Ponds unfortunately do not stay clean forever. Plants become overgrown and fish waste, leaf and organic debris build up in the pond over time. This detritus begins to break down and become anaerobic.  The decomposition of this debris gives off toxic gases that can severely stress or even kill your fish.

So the best solution is a deep pond clean removing the excess waste you can re-establish a crystal clear pond and increase the depth of water, thus increasing space for the fish and reducing your pond maintenance regime.


Steps to pond cleaning

  1. To start the pond cleaning some of the water is pumped out into our temporary vat to be kept and reuse.
  2. The koi/fish are kept safely in our vat of pond water for the duration of the cleaning along with any wildlife.
  3. The aquatic plants are then carefully removed from the pond.
  4. The remaining dirty pond water is then pumped out of the pond.
  5. The sludge in the bottom of the pond is either vacuumed out or removed by hand and placed onto the garden/ flower beds. This is an excellent organic fertilizer.
  6. The pond liner is then carefully pressure washed and all debris removed
  7. Aquatic plants are divided and cut back if necessary.
  8. The majority of pond is then refilled using the pond water from the vat and the remaining topped up using a dechlorinator
  9. The koi/ fish are then returned to the clean pond.
