Biological Filters

Biological filters are a cornerstone of any effective pond filtration system, essential for maintaining a healthy and balanced aquatic environment.

These filters utilise beneficial bacteria to break down harmful ammonia and nitrites produced by fish waste and organic matter. By converting these toxic substances into less harmful nitrates, biological filters help to prevent toxic build-ups that can harm fish and plants.

These filters typically consist of media with large surface areas, providing ample space for bacterial colonisation. Regular maintenance, such as cleaning and ensuring proper water flow, is crucial for the filter's efficiency.

Biological filters not only enhance water clarity but also contribute to the overall health and stability of your pond ecosystem, making them indispensable for any pond owner seeking a sustainable and low-maintenance solution.
