Hagen Fluval 3 Carbon Cartridge Insert, 3-Pack

The Fluval 3 Carbon Sleeve Insert has been specially designed to trap large amounts of particulate and liquefied waste from the water. The double fused sheath design traps solid waste before it can clog the fine pores of the powderized carbon layer. This permits higher adsorption activity for a longer period of time. The Fluval 3 Carbon Sleeve helps provide your fish with a healthy environment to live in.
