With a balanced pH range of approximately 8.3–8.6, it safely supports coral skeletal growth without drastically altering aquarium chemistry. Since calcium and carbonates are essential for coral development, maintaining proper levels is critical to prevent halted growth and declining coral health. Reef Advantage Calcium also contains magnesium and strontium in a balanced ratio (100:5:0.1, Ca:Mg:Sr), helping maintain these vital elements alongside calcium. Unlike limewater (kalkwasser), it does not have a caustic pH and will not deplete magnesium or alkalinity when used as directed.\u003c\/p\u003e\n\u003ch2 data-start=\"883\" data-end=\"904\"\u003e\u003cstrong data-start=\"886\" data-end=\"904\"\u003e Key Features\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul data-start=\"906\" data-end=\"1185\"\u003e\n\u003cli data-start=\"906\" data-end=\"946\"\u003e\n\u003cp data-start=\"908\" data-end=\"946\"\u003eNon-caustic ionic calcium supplement\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"947\" data-end=\"992\"\u003e\n\u003cp data-start=\"949\" data-end=\"992\"\u003eMaintains natural seawater calcium levels\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"993\" data-end=\"1026\"\u003e\n\u003cp data-start=\"995\" data-end=\"1026\"\u003eBalanced pH (approx. 8.3–8.6)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1027\" data-end=\"1079\"\u003e\n\u003cp data-start=\"1029\" data-end=\"1079\"\u003eIncludes magnesium and strontium in ideal ratios\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1080\" data-end=\"1121\"\u003e\n\u003cp data-start=\"1082\" data-end=\"1121\"\u003eSupports strong coral skeletal growth\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1122\" data-end=\"1185\"\u003e\n\u003cp data-start=\"1124\" data-end=\"1185\"\u003eWill not deplete magnesium or alkalinity when used properly\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-start=\"1192\" data-end=\"1224\"\u003e\u003cstrong data-start=\"1195\" data-end=\"1224\"\u003e Product Specifications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul data-start=\"1226\" data-end=\"1400\"\u003e\n\u003cli data-start=\"1226\" data-end=\"1245\"\u003e\n\u003cp data-start=\"1228\" data-end=\"1245\"\u003eBrand: Seachem\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1246\" data-end=\"1282\"\u003e\n\u003cp data-start=\"1248\" data-end=\"1282\"\u003eProduct Type: Calcium Supplement\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1283\" data-end=\"1312\"\u003e\n\u003cp data-start=\"1285\" data-end=\"1312\"\u003eForm: Ionic Calcium Blend\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1313\" data-end=\"1344\"\u003e\n\u003cp data-start=\"1315\" data-end=\"1344\"\u003eRatio: Ca:Mg:Sr (100:5:0.1)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1345\" data-end=\"1367\"\u003e\n\u003cp data-start=\"1347\" data-end=\"1367\"\u003epH Range: ~8.3–8.6\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1368\" data-end=\"1400\"\u003e\n\u003cp data-start=\"1370\" data-end=\"1400\"\u003eAquarium Type: Marine \/ Reef\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-start=\"1407\" data-end=\"1431\"\u003e\u003cstrong data-start=\"1410\" data-end=\"1431\"\u003e Recommended Use\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul data-start=\"1433\" data-end=\"1667\"\u003e\n\u003cli data-start=\"1433\" data-end=\"1479\"\u003e\n\u003cp data-start=\"1435\" data-end=\"1479\"\u003eRestore and maintain proper calcium levels\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1480\" data-end=\"1516\"\u003e\n\u003cp data-start=\"1482\" data-end=\"1516\"\u003eSupport SPS and LPS coral growth\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1517\" data-end=\"1561\"\u003e\n\u003cp data-start=\"1519\" data-end=\"1561\"\u003eMaintain magnesium and strontium balance\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1562\" data-end=\"1608\"\u003e\n\u003cp data-start=\"1564\" data-end=\"1608\"\u003ePrevent calcium deficiency in reef systems\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1609\" data-end=\"1667\"\u003e\n\u003cp data-start=\"1611\" data-end=\"1667\"\u003eUse as part of a complete reef supplementation program\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Premier Pet","offers":[{"title":"250G","offer_id":46951246463127,"sku":null,"price":21.0,"currency_code":"AUD","in_stock":false},{"title":"500G","offer_id":46951246495895,"sku":null,"price":35.55,"currency_code":"AUD","in_stock":false},{"title":"1KG","offer_id":46951246528663,"sku":null,"price":62.0,"currency_code":"AUD","in_stock":false},{"title":"4KG","offer_id":46951246561431,"sku":null,"price":210.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/1979\/6631\/files\/1_a82f30bd-5085-4886-891e-c3398e217ab2.jpg?v=1772429613","url":"https:\/\/petsupplycentral.com.au\/products\/reef-advantage-calcium","provider":"Pet Supply Central","version":"1.0","type":"link"}
