Even when we can’t get to the water, people are compelled to bring the water to us, installing ponds in our backyards and fountains in office parks.
These commercial pond fountains provide a special benefit when you own a business, making your property seem much more inviting.
But that’s only the case when your pond seems healthy. Fewer things will make your property seem unkept like a sad-looking pond.
In this blog post, we’ll look at how circulating and aerating your pond water can keep it healthy.
The benefits of aeration and circulating
Aeration and circulation give two crucial benefits to your pond: oxygen and prevention of stratification, which occurs when the sun heats the surface water while the water below the surface stays cool.
When the warm and cool waters don’t mix, it prevents oxygenated water from reaching the lower reaches of the pond, presenting a significant threat to fish, as it boosts the chances of a “turnover.”
What is a turnover and how do I prevent it?
Turnovers happen naturally each fall. As the air temperature drops and causes the water temperature to drop with it, the layers in the pond begin to mix.
While this mixing typically won’t kill the fish when it happens gradually, a rapid turnover can endanger aquatic life by quickly diluting the pond’s oxygen.
These rapid turnovers can happen during warmer months when ponds become stratified and typically coincide with storms or high winds. Cold rains or gusting winds from a storm front can cause rapid mixing and trigger a fish kill.
You can prevent a turnover by:
1.Making sure your commercial pond fountains are properly constructed
The ration of surface water to deep water is a significant factor in determining the frequency and severity of turnovers.
Deep ponds that have smaller surface areas are more susceptible to harsher turnovers because there’s more deep, low-oxygen water compared to oxygenated water on the surface, while shallow, broad ponds are less at risk because less of the water is low-oxygen.
2. Weed prevention
Make sure you keep aquatic weeds from covering more than 20 percent of the surface of the water. Weeds – both on the surface and submerged – hinder circulation and oxygen diffusion and remove oxygen from the water as they decay.
3. Cut down on nutrients, cut back on algae
When your pond becomes overloaded with nutrients – from lawn fertilizer, exposed sediment, animal waste and people feeding ducks, fish, etc. – it causes algae to grow, which can further deplete oxygen.
4. Mechanical circulation
Mechanical circulation systems can prevent stratification and bring water from the depths of the pond up to the surface so it can be exposed to oxygen. These systems never allow the pond to form layers, meaning you won’t have a low-oxygen section on the bottom and won’t be as at risk for fish kills.
