It is an essential building block in the formation of calcium carbonate, which makes up the skeletons of SPS and LPS corals, as well as the shells of invertebrates and coralline algae. Without sufficient calcium, coral growth slows, and overall health can become compromised.\u003c\/p\u003e\n\u003cp data-start=\"770\" data-end=\"1049\"\u003eMaintaining stable calcium levels ensures consistent skeletal growth, vibrant coloration, and strong biological processes throughout your reef system. Together with balanced alkalinity and magnesium levels, calcium forms the backbone of a healthy and stable marine environment.\u003c\/p\u003e\n\u003cp data-start=\"1051\" data-end=\"1342\"\u003e\u003cstrong data-start=\"1051\" data-end=\"1068\"\u003eKey Benefits:\u003c\/strong\u003e\u003cbr data-start=\"1068\" data-end=\"1071\"\u003e• Supports coral skeletal and shell formation\u003cbr data-start=\"1116\" data-end=\"1119\"\u003e• Promotes healthy growth of SPS, LPS, and coralline algae\u003cbr data-start=\"1177\" data-end=\"1180\"\u003e• Enhances overall reef stability and vitality\u003cbr data-start=\"1226\" data-end=\"1229\"\u003e• Prevents calcium depletion that can slow coral growth\u003cbr data-start=\"1284\" data-end=\"1287\"\u003e• Works synergistically with alkalinity and magnesium\u003c\/p\u003e\n\u003cp data-start=\"1344\" data-end=\"1383\"\u003e\u003cstrong data-start=\"1344\" data-end=\"1367\"\u003eRecommended Levels:\u003c\/strong\u003e\u003cbr data-start=\"1367\" data-end=\"1370\"\u003e420–460 ppm\u003c\/p\u003e\n\u003cp data-start=\"1385\" data-end=\"1607\"\u003e\u003cstrong data-start=\"1385\" data-end=\"1408\"\u003eDirections for Use:\u003c\/strong\u003e\u003cbr data-start=\"1408\" data-end=\"1411\"\u003eAdd 5 ml of Calcium per 100 L (25 gal) of aquarium water to raise calcium levels by 7.5 mg\/L (ppm).\u003cbr data-start=\"1522\" data-end=\"1525\"\u003eTest calcium levels regularly and adjust dosage as needed to maintain stability.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"\/pages\/reefcalculator\"\u003eCalcium Dosing Calculator\u003c\/a\u003e\u003c\/p\u003e","brand":"Waterbox Aquariums","offers":[{"title":"500ml","offer_id":47599098822834,"sku":"G2000","price":11.99,"currency_code":"USD","in_stock":true},{"title":"1000ml","offer_id":47599098855602,"sku":"G2005","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/5103\/3778\/files\/Calc.500_140f5aac-4b3f-4b0e-babc-e735b85b4f0f.jpg?v=1781818941","url":"https:\/\/marenmarine.com\/products\/calcium","provider":"Maren Marine","version":"1.0","type":"link"}
