Guarantee safe & Secure checkout
Featured Products
Fluval BioMax Bio Rings have a complex pore system creating an optimal environment where biological activity can thrive. The BioMax Media Inserts have more capacity than most biological filter media and allow ideal water movement throughout the media, to ensure optimal contact time for efficient biological filtration. With more capacity than most biological filter media, Fluval BioMax Media Inserts help reduce ammonia and nitrite. 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.
