Winter will be arriving soon and you have to prepare your Koi fish pond that this season. Winter is the season when your Koi pond will be quiet and with only a few things happening. However, there are certain measures that should be taken to make sure the Koi pond and the Koi fish will survive throughout Winter.
Clean Up - Reserve one week to take care of your Koi fish pond. Clean it up and remove unwanted bulk material in and around your pond. Inside your pond, remove all leaves, dirt and other material from the bottom. Also, remove any plants or flowers that you know for sure that will not make it through the winter. Around the pond, clean up anything that the wind can blow into your pond, as you are not likely to notice this debris until the end of winter. Taking the time to make sure that as much debris is removed as possible will prevent potentially harmful bacteria and parasites in the future.
Stop Feeding – During Winter you must stop feeding your Koi fish. With temperatures hover around 55 to 60 degrees they should only be fed once a day, when the temperature drops below 50 degree for the first time, stop feeding completely.
Check Up – All your equipment should have a seasonal check. From filtration system to your store of preventable medications you should check if everything is in order once during winter it is more difficult to find products for your Koi and Koi fish pond.
Prepare For Cold Weather – When you search for a Koi fish pond heater always keep in mind your Koi pond size. If the heater is too small for the size of the pond you have, for sure ice will still form.
Turn Off All Water Sources – Waterfalls, streams and constant moving fountains should be turned off during Winter. They keep the water circulating and therefore it is more difficult to keep the water at the right temperature. The heater must work alone to keep the water at the right temperature to keep your Koi fish alive and the pond in great conditions.


I see you say turn off water which I guess includes filters for the winter, but surely to have some air bubbles in the main pond will keep the water ciculating.
