Filter Location Bullfrog SpaWhen in doubt, always measure the existing filter by measuring the length, diameter and inner circle diameter if the center has a hole.  If there is no opening hole in the center of the filter, then note how the ends are configured.  Top endcaps may be solid or have handles or strings. Bottom end caps may have threaded connections (usually either 1 1/2″ or 2″) or other endcap types.
