The Tetra Whisper internal aquarium filter is the ultimate in quiet, convenient 3-stage filtration. The dual-sided mesh of the Bio-Bag catches debris and fish waste while the activated carbon absorbs odors and discoloration. Biological filtration is provided by the Bio-Scrubber. Bio-Scrubber鈥檚 anti-clog design provides complete biological filtration with the convenience of less maintenance. Because the Bio-Scrubber has a solid back, water is forced to flow evenly over the bacteria-rich bristles. The filter is submersible. Dimensions: 18.94鈥?L x 12.69鈥?W x 8.19鈥?H.
