{"product_id":"calcion-p","title":"Calcion -P","description":"\u003cp\u003e\u003cspan\u003eCalcium is required for the formation of aragonite, the skeletal material of reef-building invertebrates such as corals, clams, tube worms, and their respective allies. In reef aquaria, maintaining calcium within a range of 412 - 450 ppm will enable corals and other reef-building invertebrates to grow rapidly when all other physical and chemical requirements are met. [Magnesium, strontium, and carbonate ions are also complexed into aragonite, and their importance in a reef aquarium cannot be overstated.] The rate at which calcium is extracted from the water is determined by the stocking density of reef-building livestock, type of lighting, and other biological, physical, and chemical conditions; therefore, each aquarium will have different requirements for the rate of calcium supplementation.\u003c\/span\u003e\u003c\/p\u003e","brand":"PET’S HOUSE","offers":[{"title":"200g","offer_id":43198008000725,"sku":"CALP200","price":19.99,"currency_code":"USD","in_stock":false},{"title":"400g","offer_id":43198008033493,"sku":"CALP400","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0647\/6369\/1221\/products\/image_a1d4ee78-195d-4f01-b108-f9a71636e0fe.webp?v=1655153159","url":"https:\/\/pets-house-f615.myshopify.com\/products\/calcion-p","provider":"PET’S HOUSE ","version":"1.0","type":"link"}
