Bio-Bag cartridges are tough on the debris that makes aquariums nasty. Ultra-activated carbon absorbs odors and discoloration and dense, dual-sided mesh catches debris and fish waste better than other brands to keep your fish tank clean. Replace cartridges once a month for maximum filter efficiency. These disposable filter cartridges are easy to use and work to help keep your fish tank in tip-top condition. The ultra-activated carbon is designed to remove discoloration, contaminants, and foul odors while the dense, double-sided mesh works to trap debris and fish waste.

Tip: Replace Bio-Bag cartridges when water begins to overflow excessively from the Wonder Tube chamber.
