How Do Pond Filters Work?

For being such small machines, pond filters have some truly remarkable capabilities. They are responsible not only for keeping your pond water clean, but also for making sure it stays healthy. That's not an easy task when you consider that the water itself is a breeding ground for harmful bacteria, but these essential pond supplies are designed to take on the challenge.

In order to combat the many forms of debris and biological waste that form in your pond's water, your pond filter must perform three different kinds of filtration:

* Biological Filtration: In this stage of filtration, beneficial bacteria are given a place to grow within your pond's filter. These unique life forms are responsible for breaking down the harmful toxins that threaten to accumulate in your pond. Ammonia from fish waste is one of the biggest contributors, so beneficial bacteria spend most of their time breaking that down before it can harm your pond life.



* Mechanical Filtration: This is the most straight-forward of the filtration processes. During mechanical filtration, the dirty water flows through your pond filter and the filter media inside of it trap the dirt and debris that are present. The clean water is then sent back out into your pond, and the process begins with a new section of dirty water. One important thing to note is that the filtration media you choose need to be as fine as the particles it is responsible for removing.



* Chemical Filtration: This process takes care of any harmful compounds that remain after biological filtration and mechanical filtration have done their respective jobs. Chemical filtration helps to control and change specific water conditions that may not be beneficial to your pond's health. Growing pond plants in your backyard water garden is an effective way to implement this type of filtration.



Pond filters use all three types of filtration to create a healthy environment in your backyard water garden. Without these important processes, your pond's water quality would suffer and there would be a greater chance for impurities to flourish. Take care of your pond life by purchasing a high-quality pond filter this season.
