AQUATOP PF-400 Power Filter
Eliminate foul odors and clarify murky water with AQUATOPs powerful, convenient, and easy to install PF Series of hang-on filters. For tanks up to 20 gallons, the PF400 is a 2-stage hang-on filter that features mechanical and chemical filtration as well as an adjustable flow rate and easy to change filter insert enhanced with AQUATOPs Activated Carbon.
How Does It Work? As water passes through the cotton wrapped carbon insert, it goes through the chemical filtration process allowing the carbon to remove discoloration, odors, and other impurities from your water. Next, it will pass through the dense filter cotton to mechanically remove any large particles floating in your water, helping to maintain your crystal clear water.
