Description

Zeolite is used in biofilters for fish ponds as a type of substrate to promote the growth of beneficial bacteria. These bacteria are responsible for breaking down harmful waste products, such as ammonia and nitrite, into less toxic compounds like nitrate. In a biofilter, water is pumped through a chamber filled with the zeolite substrate, allowing the bacteria to colonize and grow on the surface. As the water flows over the zeolite, the bacteria use the waste products as a food source, breaking them down into less harmful compounds. The use of zeolite in biofilters is beneficial because it provides a large surface area for the bacteria to grow on and it has a natural ability to absorb and retain ammonium ions. This helps to maintain a stable and healthy environment for fish in the pond by removing toxic waste products. Additionally, zeolite is a relatively low-cost and readily available material, making it a popular choice for use in fish pond biofilters.
