It replaces the Hayward CX580XRE element.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eChecking the fit\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe cartridge measures 7 inches in diameter and 19.6 inches tall, with a 3 inch inside diameter on the top and bottom caps. That length appears in one source as 19-5\/8 inches, which is the same figure written as a fraction. Measure the old element against those numbers before ordering if you are unsure which generation of tank you have.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eReplace the set, not one element\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA SwimClear tank in this size class runs several cartridges together. Fitting one new element beside worn ones does not restore the filter, because the fresh cartridge simply takes the load the old ones no longer catch and clogs faster. Change the full set and the tank runs at rated area again.\u003c\/p\u003e","brand":"Unicel Filter Cartridges","offers":[{"title":"Default Title","offer_id":48629137178836,"sku":"UNI-60-5730","price":76.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_1cac97d4-5edd-4e34-8457-29f1e172b951.jpg?v=1788759945","url":"https:\/\/www.activepoolsupply.com\/products\/cartridge-81-sqft-c-3025","provider":"Active Pool Supply","version":"1.0","type":"link"}
