Product DescriptionFluval Quick-Clear Water Polishing Pads are uniquely designed to fit Fluval Canister Filters. These extra thick, micro-fine polyester pads effectively trap micro particles and debris as water passes through. Fluval Water Polishing Pads are ideally used when cloudy water occurs or after tank maintenance. Rinse the pad thoroughly before inserting in the aquarium filter, and it fits in the upper media basket of your Fluval 306/406 and 307/407 canister filters. Pads should be replaced every 3 months, or sooner if the pad becomes clogged and fi¬lter flow-rate diminishes.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.Amazon.comFluval Water Polishing Pads are uniquely designed to fit Fluval Canister Filters.
