Fluval Pre-Filter Media is designed to capture solid waste before it reaches other media. This prevents premature clogging of finer filters and extends their life, reducing media replacement frequency. Fluval Pre-Filter consists of inert, solid ceramic rings used to trap large and medium solid particles before they clog the finer sieves of the modules above. The diversified water flow allows establishment of biological activity on the surface of the rings, adding to the overall biological action on ammonia and nitrite. Fluval Pre-Filter Media is ideal for medium and coarse filtration, and suitable for both freshwater and marine aquariums.
Fluval first broke onto the aquatic scene in 1975 by introducing the world's first 3-stage filter with synchronous motor technology – a landmark breakthrough that is still applied in the industry today. Since then, Fluval has built a legacy around this pioneering spirit, relentlessly adapting in a changing world to launch innovative aquarium products that remain at the forefront of technology, and which set the bar in quality, style and functionality. Above and beyond its manufacturing role, Fluval prides itself on its charitable and educational efforts that give back to the fishkeeping community, whether it means helping to fund the protection of wild coral reefs or jumping on a plane to document endangered fish species halfway around the world. Fluval's mission is not just about building products that mimic the natural world, but inspiring aquarists of all skill levels to enjoy and respect the hobby for generations to come.
