Considering Options for Insulating Koi Carp Pool

Our pond is heated, with the thermostat set at 15 degrees C (59 degrees F) When working from home, I would watch the steam rising from the pond each morning, thinking, we’re paying for that steam!

A cover of some description was required, but what properties must it have?

  • It must not blow away – our rear garden is very windy
  • If it does blow away, it must not cause any damage
  • It must not look too ugly
  • It must pack away for the summer without needing a second garden to store it
  • We must be able to feed the fish
  • The fish must not be able to strand themselves by jumping on top of the cover

What we considered:

Anything else?..

Well, they form nice geometric shapes on the pond surface after the wind has blown them about a bit. The fish can still feed through them and appear to enjoy pushing the balls about. I use some pieces of waste pipe to form a 1m x 1m area, without balls, for feeding.

They are easy to store, just put them back into the plastic bag and cardboard box they came in and store them in the loft. The only downside is that they can get covered in algae on the bottom, we are thinking of adding salt to the pond this winter so we expect that to solve the algae problem.
