{"product_id":"purple-urchin","title":"Purple Urchin","description":"Purple sea urchins are striking additions to established reef aquariums, prized for their vibrant coloration and algae-grazing behavior. These hardy invertebrates help maintain a balanced ecosystem by consuming unwanted algae and detritus, reducing maintenance demands on your system.\n\nCare is straightforward for intermediate aquarists. Provide stable water parameters—salinity 1.023–1.025, pH 8.1–8.3, and temperatures between 72–78°F. Strong water flow and plenty of rockwork with crevices allow them to graze naturally and find shelter. Feed occasionally with dried seaweed or algae-based supplements if algae growth is limited. Avoid aggressive tank mates and sudden parameter swings, as urchins are sensitive to rapid changes.\n\nA thriving purple urchin signals a healthy reef—one where natural processes work in harmony with your care routine. Perfect for hobbyists ready to elevate their aquascaping with both function and oceanic beauty.","brand":"Saltwater Reef Co.","offers":[{"title":"Default Title","offer_id":46650908868798,"sku":"IPUSS609","price":60.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/1541\/4462\/files\/lg-36794_HairyPincushionUrchinPurple.webp?v=1776456438","url":"https:\/\/saltwaterreefcoshop.com\/products\/purple-urchin","provider":"Saltwater Reef Co.","version":"1.0","type":"link"}
