This one is 8-11\/16 in. outside diameter, 18-3\/16 in. long, and its end is open with 12 concentric slots. If the element in your tank measures the same and its end matches, this is the replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to change it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA cartridge is due when cleaning no longer brings the filter pressure back down to where it started, when the pleats have gone hard and gray, or when the fabric has torn or the end caps have pulled loose.
