A compact cartridge is serving a smaller body of water, so the ratio of bather waste to water volume is often higher than in a large spa — which means oils and debris concentrate faster. Sticking to a consistent rinse and deep-clean routine is what keeps a smaller spa's water as clear as a big one's.\u003c\/div\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv class=\"lti-pro-tip\"\u003e\n\u003cp\u003e\u003cspan aria-label=\"®\" role=\"img\"\u003eCaldera®\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Caldera","offers":[{"title":"Default Title","offer_id":46961525391556,"sku":"qzp1791364415016","price":28.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0707\/9690\/2596\/files\/caldera-74148-35-sq-ft-aventine-spa-filter_1.png?v=1791364423","url":"https:\/\/mydoventa.com\/products\/caldera-74148-35-sq-ft-aventine-spa-filter","provider":"Mydoventa","version":"1.0","type":"link"}
