Fluval Carbon Filter Media for Aquariums Premium Bituminous Activated Carbon Inserts 100 Gram Nylon Bags 3 Count Pack of 1

Fluval Premium Bituminous Carbon Filter Media is a research-grade, low-ash chemical filtration solution designed to establish pristine aquatic environments. Ideal for both freshwater and marine aquariums, these high-quality activated carbon inserts feature a highly porous internal matrix structure. This expansive surface area provides exceptional adsorption capacity, working effectively as a microscopic sieve that traps minute particles, organic wastes, liquid impurities, urine, and unsightly dyes. The result is sparkling, crystal-clear aquarium water that allows your fish and aquatic life to thrive. Beyond water clarity, this premium carbon effectively eliminates stubborn odors, heavy metals, and unsightly discolorations that cloud your view. The large internal surface area also serves a dual purpose by offering numerous attachment points where beneficial bacterial colonies can establish and flourish, enhancing biological stability. Supplied in convenient, ready-to-use 100-gram nylon media bags, this three-pack offers an economical and hassle-free maintenance solution. It is fully compatible with various external canister filter models. To maintain peak performance, replace the media every four weeks. Always remove carbon during fish medication cycles as it adsorbs active treatments, and use it with careful monitoring in heavily planted tanks where it may absorb essential liquid plant fertilizers.
