Maintenance for ponds in northern climates
You have two options of how to protect your pump and filters. Whatever option you choose, it should done before the ice starts to form
Option one
Add a de-icer or aeration system which may prevent the pond surface from completely freezing over. Proper oxigen/carbon dioxide gas exchange will help the pond fish to survive. Remove, clean and store the pump for the winter.
Option two

The store where I purchased the pond pump and filter system recommended to remove the pump from the pond and store the pump during the winter in a bucket with water in a frost free location. This will prevent the seal and/or gasket from drying out and thereby extend the life span of the pump. The filter should be cleaned one more time so that it is ready to be used again next spring.
- Remove any pond plants that are not expected to survive the winter.
- To release pressure created when water turns into ice throw in a few swimming pool noodles and/or tennis balls.
- Snow should be removed from the ice surface to allow light to enter the pond. - Do not feed the fish during the winter.

Pond Maintenance. Pool chemicals. Ponds in northern climates
There isn't much maintenance required for my small backyard pond that has no fish or pond plants. I have to clean the filter only twice each season, from time to time add some liquid Algaecide to control algae growth and if there is not enough rainfall I will have to add water to replace water lost through evaporation. I do not drain the water before winter sets in but in the spring I empty the entire pond and do a thorough cleaning so decomposed leaves will not clog the pump intake and filter system. Throughout the summer I use a small net to skim the water surface and remove any blown in debris.
Larger ponds with fish and plants require regular maintenance in order to maintain life and water quality. Here are some of the things that you should do on a regular schedule: - Clean the filter and pump. - Keep plant growth under control by cutting away excessive plant material. - Control algae growth which can deplete the oxygen levels in the water. - Replace water lost through evaporation but don't top up the pond water all at once. This should be done in small amounts to prevent rapid changes in water temperature and chemical levels. - Check for and maintain proper PH levels so your fish will stay healthy - In the fall cover the pond with pond netting to keep the pond as leaf free as possible. Leaves will settle on the bottom of the pond and decay during the long winter months. Decayed organic matter may clog the pond pump intake, pond filter system and effect water quality. The garden centre near where I live carries pond netting in two sizes, 7'x10' (2x3 m) and 14'x20' 4x6 m). I prefer to cover my pond with green netting which is sold from a roll 13' (4 m) wide. Green netting is mainly used for wrapping cedar trees to prevent snow damage. It is sold in the same store section where they sell bulk burlap.

Pond stores and garden supply centres carry a wide variety of pond nets and chemicals
