Made from highly pure calcium hydroxide, it dissolves efficiently to create kalkwasser for dosing through top-off systems or manual supplementation. This method is widely used by reef aquarists to promote strong coral skeletal growth and maintain stable reef chemistry.\u003c\/p\u003e\n\u003cp data-start=\"606\" data-end=\"880\"\u003eMany reef keepers dose kalkwasser through an \u003cstrong data-start=\"651\" data-end=\"680\"\u003eAuto Top Off (ATO) system\u003c\/strong\u003e, where evaporated water is replaced with kalkwasser solution. This allows for slow, consistent dosing throughout the day, helping maintain stable calcium, alkalinity, and pH levels in reef aquariums.\u003c\/p\u003e\n\u003cp data-start=\"882\" data-end=\"1220\"\u003eKalkwasser dosing can be an effective way to maintain calcium and alkalinity simultaneously while helping buffer pH levels. Due to its potency, it is best suited for reef keepers comfortable monitoring water chemistry and dosing carefully. Ideal for marine reef systems with stony corals, clams, and other calcium-consuming invertebrates.\u003c\/p\u003e\n\u003cp data-start=\"1222\" data-end=\"1245\"\u003e\u003cstrong data-start=\"1222\" data-end=\"1245\"\u003eFeatures \u0026amp; Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1247\" data-end=\"1561\"\u003e\n\u003cli data-section-id=\"11k25vr\" data-start=\"1247\" data-end=\"1299\"\u003e\n\u003cp data-start=\"1249\" data-end=\"1299\"\u003eHigh-purity calcium hydroxide for reef aquariums\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"14dkr\" data-start=\"1300\" data-end=\"1341\"\u003e\n\u003cp data-start=\"1302\" data-end=\"1341\"\u003eHelps maintain natural calcium levels\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"1cxkk40\" data-start=\"1342\" data-end=\"1401\"\u003e\n\u003cp data-start=\"1344\" data-end=\"1401\"\u003eSupports carbonate alkalinity through kalkwasser dosing\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"x9s4f1\" data-start=\"1402\" data-end=\"1469\"\u003e\n\u003cp data-start=\"1404\" data-end=\"1469\"\u003eCommonly used with Auto Top Off (ATO) systems for stable dosing\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"16xi2da\" data-start=\"1470\" data-end=\"1520\"\u003e\n\u003cp data-start=\"1472\" data-end=\"1520\"\u003ePromotes healthy coral and invertebrate growth\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"zdamlx\" data-start=\"1521\" data-end=\"1561\"\u003e\n\u003cp data-start=\"1523\" data-end=\"1561\"\u003eSuitable for marine and reef aquariums\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Simply Fish","offers":[{"title":"Reef Kalkwasser 500g","offer_id":42777217007693,"sku":null,"price":59.99,"currency_code":"NZD","in_stock":true},{"title":"Reef Kalkwasser 1kg","offer_id":42777217040461,"sku":null,"price":99.99,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0571\/2180\/0269\/files\/LM46.png?v=1773375533","url":"https:\/\/simplyfish.store\/products\/seachem-reef-kalkwasser","provider":"Simply Fish","version":"1.0","type":"link"}
