{"product_id":"caribsea-purple-up-4oz","title":"Caribsea Purple Up 4oz","description":"\u003cp\u003ePurpleUp™ – uses a unique dual method approach to coralline algae acceleration. This approach is so unique that PurpleUp™ has been awarded a US patent (US patent No. 7,565,883). It contains ionic calcium; which immediately raises dissolved calcium levels in your aquarium water. At the same time Super Sea Calcium™ (a 10 micron aragonite powder derived from natural seawater) targets the live rock surface. This dissolves in situ; delivering calcium, strontium, magnesium, and carbonate right where it’s needed. PurpleUp™ also replenishes iodine; an essential element for coralline algae tissues that quickly becomes depleted in closed systems. PurpleUp™ is not a fertilizer, it does not promote the growth of nuisance algae.\u003c\/p\u003e","brand":"Caribsea","offers":[{"title":"Default Title","offer_id":57054963925323,"sku":"780733","price":11.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1033\/7065\/4027\/files\/s-l1600_6.jpg?v=1776427417","url":"https:\/\/krakencorals.co.uk\/products\/caribsea-purple-up-4oz","provider":"Kraken Corals","version":"1.0","type":"link"}
