Gravity filtration differs from pressurized because the water is not getting pumped from the pond into the filter. In a gravity filter system for example, debris can settle to the bottom of your pond into a bottom drain, along pipes and into the filter. After it has been filtered the water is then pulled by a pump back into the pond. Because the water does not pass through the pump until after it has been filtered, fish waste does not get purred and sent back into your pond.
