Keeping your pond well oxygenated is incredibly important; not only does it maintain the health of the pond’s fish population, it also impacts the pond’s entire ecosystem too.
This is especially important in the warm summer months, when heat causes the oxygen levels in a pond to deplete. This is why on a hot day, you’ll often notice fish gasping at the water’s surface for air.
Thankfully, oxygenating your pond is one of the more simple pond maintenance tasks that you’ll need to carry out. Read on below for our simple steps on how to add oxygen to your pond!
Installing a Pond Pump
Pond pumps are means of keeping the water in your pond constantly flowing, thus oxygenating the water in the process. As well as circulating and aerating the water, pond pumps also drive water through filtration systems, resulting in a cleaner, healthier pond.
Installing a Fountain
The installation of a fountain not only improves your pond aesthetically, it’s also an inexpensive means of aerating it too. The addition of a fountain means that water is constantly breaking the surface, thus oxygenating the pond in the process, keeping your fish and plantlife healthy.
Pond fountain pumps come in all sorts of shapes and sizes, so make sure that you find the right fountain for you. Things to consider include the noise and appearance of the water jet, as well as the trajectory of the water itself.
When used during the warmer months of the year, Airstones steadily bubble a supply of air into the water, also gently breaking the surface and increasing surface agitation to both release carbon dioxide and introduce more oxygen.
Spray With a Hose
In an emergency such as a power cut or extreme period of warm weather, simply spraying your pond with a hose is a great way to oxygenate the pond at short notice. Hosing the pond’s surface breaks the water and allows both oxygen in and carbon dioxide out.
When using this method, make sure to use a suitable water conditioner to remove dangerous chlorine, chloramine and heavy metals from the tap water.
Decrease Plant Life
Although plants perform photosynthesis during the day, absorbing carbon dioxide and releasing oxygen, this process ceases during the evening hours. Plants however continue to require oxygen to grow, producing waste carbon dioxide in the process – so it makes sense that plant life will have an impact on the oxygen levels of your pond, especially after nightfall.
During the hot summer months, the increased sunlight will often result in your pond plants growing quicker, thus removing more oxygen from the pond. Keeping on top of the plant life in your pond and using weed removal treatment to prevent duckweed, blanketweed and other invasive plants – you’ll start to notice an improvement in oxygen levels too.
