Prepare your Pond for Winter with Nature's Pond Care
As Winter approaches, there are a few things all pond/dugout owners should consider when preparing for this season. We need to aware of temperatures to ensure the best transition for their ponds and everything living in them. If you are living in a climate that has cold winters and snow, it is especially important to prepare your pond.
Prevent Organic Matter from Entering the Pond
In the fall trees will begin to prepare for winter by shedding their leaves. Plants and crops die off and rains will create run off which brings additional loads of organic matter in to ponds. If your pond is surrounded by trees, crops or other plants you want to reduce the amount of dead leaves and plants that enter the water. Either by trimming trees and brush near the pond to prevent them from falling into the water, or by raking them away before they come in. The more dead matter that enters the pond, the worse off the body of water will be.
Organic matter that comes into the pond will start to decompose and in the process, will deplete needed oxygen from the water that is used for other purposes such as keeping fish alive and ensuring the pond does not become stagnant and smelly. This organic matter will also build up layers of muck and sludge at the bottom of water which leads to higher nutrient levels causing unnecessarily high growth of algae and weeds the following spring and summer.

Reduce Nutrients and Organic Matter in the Pond
Ponds and pond life begin to slow down as colder weather sets in. Most of the beneficial bacteria and enzymes applied in the spring and summer that are used to consume excess nutrients in the water have now died off. At this time we suggest you consider adding a blend of bacteria and enzymes that work in colder water temperatures.
Nature’s Pond Conditioner Fall/Winter blend is a special blend of naturally occurring bacteria, enzymes, and plant extracts, formulated with a preservative that adds to the longevity and productivity of the bacteria and enzymes through the colder weather conditions. It enables the microbes to keep consuming and cleaning the debris, run off, and decaying matter in your pond throughout the winter months. By doing this you avoid getting that smelly rotten egg odor that starts to occur during the winter and spring. It also helps the water remain clean and clear all winter long thus providing a healthier pond environment for your fish, pets and livestock.
Maintain the Pond’s Health with Aeration
We cannot stress enough the importance of aerating a pond in the winter. Oxygen levels in the water can become fatally low which can cause harm to the life it supports.
Here is a short timeline of what will happen to your pond if it is not aerated in the winter:
Ice covers the dugout in early winter and prevents the wind from mixing the water.
Snow and ice cover the pond and the shade prevents adequate levels of oxygen to be produced through photosynthesis.
Dead algae at the bottom of the dugout begin to decompose consuming the already depleted oxygen resource at the bottom of the dugout.
The oxygen is not replaced and the absence of oxygen in the water allows plant nutrients and metals which are trapped in the sediment to dissolve into the water.
Later in the winter, the absence of oxygen results in the release of hydrogen sulphide (rotten egg smelling gas). More nutrients and metals are released into the water at the bottom of the dugout and the layer of poor quality water increases in thickness.
You can notice taste and odour problems when the poor-quality water reaches the intake and is pumped into the house for use.
When spring arrives, the heat from the sun melts the ice and creates a uniform water temperature throughout the dugout. The uniform temperature allows the wind to mix the dugout bringing nutrient rich water from the bottom to the surface. Spring runoff adds a small amount of plant nutrients in comparison with that released from the sediment during the winter.
To avoid all the problems that can occur during and after winter the best solution is "Bottom Up" Aeration. Aerated ponds will typically have an open area of water. This open water is due to the constant circulation of air bubbles rising from the bottom to the surface. The amount of open water is determined by the type of diffusers used and the overall efficiency of the aeration system.
Prepare your Pond Equipment
Freezing can cause damage, wear and tear on aeration systems. If you are in a colder climate then we recommend attaching the Koenders Freeze Control Unit. Whenever you compress air condensation can form in the airline and can create an ice blockage if it is cold. With a freeze control unit alcohol will be automatically be injected to melt the ice. This will help ensure aeration during winter as well as help protect the compressor from back-pressure due to blockages. We recommend using Isopropyl Alcohol at 90-99% purity.
For Koenders customers in colder climates we also recommend a pressure release valve and weighted airlines. A pressure release valve will protect your compressor from back-pressure due to line blockages like ice buildup or a twisted hose. Eliminating back-pressure will increase the lifespan of your unit. It is recommended to use weighted airlines in the water so that it does not float in your pond. This will help prevent lines freezing in the ice layer on top of the pond and cracking.
