What is a power filter, and what is the advantage of using one?
A power filter uses an electric motor connected to an impeller by a magnetic device through the wall of the
filter box. By not housing a drive shaft through the filter box, there is less chance for leaks in the system.
Power filters increase water flow through the filter media and remove more waste materials.
