How to Perform a Winter Shut Down
The first step is to determine when they should shut down their pond equipment: the pump, filter and UV clarifier. If your winter temperatures are moderate, you may continue to run their pumps to keep the pond surface from freezing. Further north, where temperatures are more extreme, you’ll want to recommended shutting the pond down for two reasons. First, the pump will mix colder surface water with the slightly warmer, more stable temperatures in the pond bottom where fish take comfort and hibernate. Second, pond owners risk the chance of diverting water out of the pond and emptying it when the flowing water begins to form ice, especially on features like waterfalls or streams.
Recommend that you store the equipment indoors safe from the elements. It’s also a good idea to clean and inspect the equipment and replace any broken components. When shutting down the pumps, filters or any other equipment remind your friends if they are storing the equipment outside or in an unheated space make sure that there is no water left in the device that may ice up and cause the body/housing to break. If kept inside it helps to place the pump, if it is submersible, in a bucket of water to keep the moving parts and seals wet.
Winter Pond Equipment
It is important to recommend and stock a de-icer product. Take the time now to educate your customers on the importance of investing in a de-icer; waiting until their pond freezes over may be too late. Gases, which are produced by decomposing organic material, are toxic to fish when they are trapped beneath ice covering the pond’s surface. De-icer’s are
designed to keep an area of the pond ice-free during the winter, allowing harmful gases to escape through the opening. In small ponds, a de-icer is especially helpful in preventing ponds from freezing solid. For fish safety, it is extremely important to never break ice on the pond because the shock waves can be detrimental, and sometimes fatal, to fish.
