A pond makes an excellent addition to any garden. It provides you with your own little patch of nature, where you can retreat at the end of a hectic day to relax and unwind amongst the sounds of wildlife and burbling water. If you are considering installing a pond in your garden, you will no doubt have come across articles discussing the necessity of a water filter in your pond. However, why is this an essential part of pond maintenance? Surely building a pond simply means digging a hole and filling it with water? Read on to find out more about why installing a water filter is so important for the success of your pond.
Mechanical filters to prevent rotting vegetation
Water filters use several different methods of cleaning your pond water to ensure that it is kept crystal clear. Visit water-garden.co.uk for more information on the different types of filtration systems used in water filters. Mechanical filters work by removing larger items from the water, such as debris, fallen leaves, and surface algae. If left uncollected, this fallen vegetation debris can rot away into the water, producing toxins that eventually build up and create an unpleasant and unhealthy aquatic environment that will deter wildlife but encourage the proliferation of bacteria and parasites.
Biological filters to clear green water
If your pond water is more pea soup than aquatic paradise, this is a sign that the water quality is poor. Green pond water is caused by tiny floating algae that rapidly spread, as well as stagnant water and a high pH level. It is a particularly common problem in new ponds containing water that is rich in nutrients, such as tap water that has yet to be matured into the aquatic ecosystem. Water filters help to combat green water by using biological filtration. This produces beneficial bacteria that digest pond nutrients produced by waste products and break down the ammonia and nitrate contents within the pond, therefore creating a healthier water environment.
Chemical filters to remove other toxins
Water filtration systems also use chemical filters in order to remove other toxins and pollutants from the water that have escaped mechanical and biological filtration. For example, if you keep fish in your pond, chemical filters will remove the waste that they produce. This ensures that the pond water is maintained as a safe and clean environment in which your fish can thrive.
To provide flow of oxygen to prevent stagnation
Stagnant water occurs when water stops flowing and oxygen is not dissolved in it. It is an environmental hazard, as stagnant water is a prime breeding ground for bacteria and parasites, and can result in deadly diseases such as malaria. Stagnation is of particular concern in an artificial pond, as it lacks the natural currents that keep the water moving. In this case, a water filter does the job of artificially keeping the water flowing to ensure a good flow of oxygen and help maintain a healthy aquatic environment.
