If you have a fish pond you’ll need to know the how to take care of the fish during the winter. If the country you live in has a cold winter then you need to take this into account when you build your fish pond. You need to made at least part of your pond 30 to 45 inches deep in order to protect your fish during very cold spells. If the pond becomes iced over toxic gases can build up in the water, so it is essential that you make sure that part of the surface is always open to to allow the toxic gases to escape and to allow oxygen to enter. You can achieve this in different ways.

An aerator, powered by a small aquarium pump can be used to keep an opening in the ice. It is quite hard to get the placement correct so that it works efficiently. It should be placed about half way to the bottom of the pond. If it is too deep it can cause the whole pond to be chilled, too near the surface it can freeze.
