Fluval Pre-Filter Media consists of inert, solid ceramic rings designed to be the crucial first stage of your aquarium's filtration system. This media effectively traps large and medium solid particles, preventing them from prematurely clogging the finer sieves and more delicate media in subsequent filter baskets. By forcing water through a myriad of complex paths, it significantly increases both its mechanical and biological filtration activity, expanding the actual contacted filter area for superior water clarity.

A significant benefit of this pre-filter media is its ability to support large populations of beneficial bacteria, which are essential for proper biological action on ammonia and nitrite. This robust biological activity reduces the need for frequent changes of active filter media, simplifying your maintenance routine. Fluval Pre-Filter is a permanent media, requiring only occasional rinsing to maintain its effectiveness, and it can be seamlessly used in both freshwater and marine environments without difficulty. This package contains 750 grams of media.

This product is best for any saltwater reef aquarium owner seeking to enhance their filtration system's overall efficiency and longevity. It is particularly valuable for those looking to improve water quality, extend the life of their expensive chemical and biological media, and reduce the frequency of filter maintenance. Its dual mechanical and biological capabilities make it an excellent foundation for a healthy and stable reef environment, ensuring cleaner water and a more robust ecosystem.
