Because it is not harvested from the ocean it is a pest-free, sustainable choice, and unlike machined shelf rock it retains a natural, irregular look. It is sold by the pound and is available in natural or coralline color.\u003c\/p\u003e\n\u003cdiv style=\"margin:26px 0 8px;border:1px solid #e3d6be;border-radius:14px;overflow:hidden;max-width:720px;\"\u003e\n\u003cdiv style=\"background:#1e535b;color:#fbf9f3;padding:13px 18px;font-size:13px;font-weight:700;letter-spacing:.08em;text-transform:uppercase;\"\u003eSpecifications\u003c\/div\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;line-height:1.5;margin:0;\"\u003e\u003ctbody\u003e\n\u003ctr style=\"background:#f7f4ec;\"\u003e\n\u003ctd style=\"padding:11px 18px;color:#566a6c;font-weight:600;width:40%;border-bottom:1px solid #ece4d4;vertical-align:top;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"padding:11px 18px;color:#123e45;border-bottom:1px solid #ece4d4;vertical-align:top;\"\u003eAll-natural calcium carbonate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:11px 18px;color:#566a6c;font-weight:600;width:40%;border-bottom:1px solid #ece4d4;vertical-align:top;\"\u003eSource\u003c\/td\u003e\n\u003ctd style=\"padding:11px 18px;color:#123e45;border-bottom:1px solid #ece4d4;vertical-align:top;\"\u003eAncient fossilized reef structures\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f7f4ec;\"\u003e\n\u003ctd style=\"padding:11px 18px;color:#566a6c;font-weight:600;width:40%;border-bottom:1px solid #ece4d4;vertical-align:top;\"\u003eTypical Size\u003c\/td\u003e\n\u003ctd style=\"padding:11px 18px;color:#123e45;border-bottom:1px solid #ece4d4;vertical-align:top;\"\u003e5\"-15\" long\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:11px 18px;color:#566a6c;font-weight:600;width:40%;border-bottom:1px solid #ece4d4;vertical-align:top;\"\u003ePest Status\u003c\/td\u003e\n\u003ctd style=\"padding:11px 18px;color:#123e45;border-bottom:1px solid #ece4d4;vertical-align:top;\"\u003ePest-free, sustainable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f7f4ec;\"\u003e\n\u003ctd style=\"padding:11px 18px;color:#566a6c;font-weight:600;width:40%;border-bottom:1px solid #ece4d4;vertical-align:top;\"\u003eColor Options\u003c\/td\u003e\n\u003ctd style=\"padding:11px 18px;color:#123e45;border-bottom:1px solid #ece4d4;vertical-align:top;\"\u003eNatural or coralline\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:11px 18px;color:#566a6c;font-weight:600;width:40%;border-bottom:1px solid #ece4d4;vertical-align:top;\"\u003eUse\u003c\/td\u003e\n\u003ctd style=\"padding:11px 18px;color:#123e45;border-bottom:1px solid #ece4d4;vertical-align:top;\"\u003eTiered\/shelf aquascaping with overhangs and caves\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Marco Rocks","offers":[{"title":"Default Title","offer_id":47595997429938,"sku":"MR-SHELF","price":4.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/5103\/3778\/files\/shelf-rock__25878.1719355943.jpg?v=1781739993","url":"https:\/\/marenmarine.com\/products\/marco-rocks-shelf","provider":"Maren Marine","version":"1.0","type":"link"}
