The relationship between water quality and filter media in fish pond filtration systems

​        Many fish lovers have heard that summer koi is good for fish because of the constant high temperatures and the abundance of fungus. Imagine how enjoyable it is to be under the shade on a summer afternoon, eating a cool watermelon and watching your favorite Koi swimming happily!

       It is true that managing koi and filtration systems is easier in the summer, but with the cooler temperatures of winter and early spring, water quality is always a concern that must be kept in check. There is a close relationship between the filter media and the water quality in a pond filtration system.

       Fish pond filtration system in the physical filter material: filter cotton, brush, etc., used to intercept and adsorb solid impurities in the water, such as fish feces, food scraps, leaves and other large particles of impurities. If these substances directly into the fish pond, increase the turbidity of the water body at the same time will also consume dissolved oxygen, resulting in deterioration of water quality, affecting the ornamental, and even triggering fish disease.

Reduction of water turbidity::

     Through physical filtration, it can effectively reduce the turbidity of the water body, make the water clear and transparent, and at the same time reduce the consumption of dissolved oxygen in the water, provide a better living environment for fish and improve the ornamental.

Transformation of hazardous substances::

       Biological filtration materials such as biochemical cotton, coral sand, ceramic rings, bio-balls, etc. provide a place for beneficial microorganisms such as nitrifying bacteria to attach and grow. These microorganisms will convert harmful substances such as ammonia nitrogen and nitrite in the water into nitrate through biological oxidation, thus reducing the concentration of toxic substances in the water body and maintaining the stability of water quality.

Inhibition of algal growth::

The biofiltration system also inhibits the growth and reproduction of algae, as excessive algae growth consumes large amounts of dissolved oxygen and produces harmful substances that affect water quality and fish health.

Removes organic matter and harmful ions::
