With any Koi Pond, Fish Pond, or water feature in general, we need to have two types of filtration. The filtration systems are Mechanical and Biological. The filtration system’s role is to keep the water clean and clear, to make it transparent and pleasing to the eye. A filtration system is also of utmost importance for all the aquatic life in your water feature and their wellbeing.

Bottom Drains

One mechanical aspect of pond filtration is the bottom drain. How do the pond bottom drains work? They simply remove or filter the organic matter, such as fish waste that has fallen to the bottom of the pond. A bottom drain system done right will create a dynamic circulation for your pond’s water and reduce its need of maintenance.


Another mechanical part of the pond’s filtration system is the Skimmer. The role of a pond skimmer is simple – it removes all debris that float on top of the water like leaves and such. The pond skimmer is a huge necessity, especially for fish ponds. All organic matter that can decay ruin the balance of your developed ecosystem, polluting the water and even endangering your fish.

Pumps and Valves

The pond pumps in a pond are the most essential part. They are what creates the water circulation in our system so their routine maintenance is primary. Without a perfectly working water circulation system 24/7 your fish pond will not survive.

One more important part of the mechanical filtration fo your water feature are the pond PVC valves. They are used for the circulation, flow control, and isolation of the water and its level. There are different kinds of valves depending on the type of water feature you have.

Filtration Media

Filtration – Solid particle filters, like the Sand/Gravel or Bead Filters, are also a necessity for a pond. Expectedly they help in cleaning the solid particles which cloud the water. Pre-filters are also used to prevent pump systems from clogging.

UV Filtration and Sterilization

Pond UV sterilizers are another essential part of your pond’s filtration system. Without and UV sterilizer bulb you cannot control the algae growth. To get rid of the algae in a pond and prevent its accumulation, you need such sterilizers. They will eliminate the green water and control the bacterias that help algae’s growth. Together with the UV clarifier, they help in keeping the water crystal clear.

The Filter’s role in the pond filtration system is self-explanatory. They refine the water quality, giving it superior clarity and full transparency. They remove the ammonia and accumulated debris, which is essential for the health of your pond, aquarium, or water system and the aquatic life within it.

The maintenance of the filtration system in any pond, aquarium or other water feature, is essential for the life within. Nevertheless, with all those filtration systems, it is important you tend to your pond, or other water feature, and help in maintaining the system itself, as well as the water quality. Our team of pond experts is always available for further assistance in the maintenance of your water feature.
