What can make a pond water dirty?

  • Biological or mechanical filters have not been efficiently serviced
  • You have not cleaned your pond in the last year

In what ways does a filter impact a pond?

To deal with the above-mentioned issues, you can apply a few fixes. One is to replace old filter media and clean the pond. Both natural and manmade filters are beneficial by offering a low-maintenance pond. This can happen in less than a day’s time by the help of trained professional. Another way is to add fish and other aquatic plants to prevent any growth of algae.

This method does not require any major reconstruction. It creates a living ecosystem that not just entertains but also promote health. The third way is to use a skimmer due to its capability to clean a lot of surface debris and dust from the pond.

How to increase the water quality in a pond?

To provide good quality of water, some type of waste removal should be provided. Two main ways that are used in an average garden pond and water garden are biological filtration and mechanical filtration.

Mechanical filters work by physically eliminating solids from the water. This is done by trapping the dust in the form of brush, mat, or sponge. Biological filtration removes toxins from garden ponds and water gardens by disintegrating ammonia into nitrite and again into nitrate.


A proper size of pond filter can benefit a pond owner by increasing pond’s life and the enjoyment that you can get from it. For the pond with the clearest water, where you can clearly see the bottom, watch fishes, and enjoy seeing the clean water, you should definitely get a filter today.
