AQUATOP PF-500 Power Filter
The PF-500 Power Filter by AQUATOP is an easy to use 3 stage hang on filter that features mechanical, chemical, and biological filtration. The PF-500 Power Filter has an adjustable flow rate and uses an easy to change drop in filter cotton pouch that is filled with activated carbon to provide you with your mechanical and chemical filtration. For biological filtration, the PF-500 has a unique "Bio-Wall" insert that allows for superior biological filtration. This hang on filter will also efficiently remove toxic ammonia and nitrite.
How Does the PF-500 Work?
As water passes through the filter, it reaches the unique Bio-Wall This is where the beneficial bacteria that is colonizing on the wall will break down the toxic ammonia and nitrite. Next, before the water returns back into the aquarium, it passes through the cotton wrapped carbon insert where the mechanical and chemical filtration process takes place. This allows the carbon to remove discoloration, odors, and other impurities from your water.
