Whisper Bio-bag Disposable Filter Cartridges

Extra Large Size Filter Cartridges contain Whisper Filter Carbon. Whisper Filter Carbon is ultra-activated and contains seven adsorbent acres of surface area per ounce. Millions of micropores within each granule adsorb and lock in discoloration, noxious odors, dissolved contaminants, and hundreds of other chemicals such as chlorine, insecticides, and detergents. Included in this package are four pre-measured packets of Whisper Filter Carbon. Tests indicate this quantity is sufficient for four Bio-Bags under normal aquarium conditions. In larger or crowded aquariums, additional Whisper Filter Carbon may be added. Bio-Bag Four Pack contains four Thick 'n Fluffy Filter Bags, four Ultra-Activated Whisper Power Filter Carbon Pre-Measured Packets, and one Aerobic Frame with Clip.
