It is essential for the growth of coral skeletons, oyster shells, and other marine organisms that rely on stable alkalinity for structural development. Soft acids formed in aquariums through oxygen respiration and the decomposition of organic matter can lower alkalinity, disrupting pH stability. Reeflowers Pure KH helps restore alkalinity and pH balance, promoting healthy coral growth and improving overall water quality.\u003c\/p\u003e\n\u003cp data-start=\"669\" data-end=\"976\"\u003eTo use, measure the kH value in your aquarium and add up to 5g per 100 liters until the desired kH level is reached. This product is ideal for reef tanks that require precise control over alkalinity and is especially beneficial when used with the balling method or a dosing pump for regular supplementation.\u003c\/p\u003e\n\u003cp data-start=\"978\" data-end=\"995\"\u003e\u003cstrong data-start=\"978\" data-end=\"995\"\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"996\" data-end=\"1529\"\u003e\n\u003cli data-start=\"996\" data-end=\"1073\"\u003eIncreases carbonate hardness (kH) for healthy coral and invertebrate growth\u003c\/li\u003e\n\u003cli data-start=\"1074\" data-end=\"1143\"\u003eEssential for coral skeleton formation and maintaining pH stability\u003c\/li\u003e\n\u003cli data-start=\"1144\" data-end=\"1235\"\u003eRestores alkalinity in aquariums affected by organic decomposition and oxygen respiration\u003c\/li\u003e\n\u003cli data-start=\"1236\" data-end=\"1291\"\u003eDosage: 2.5g of Pure kH increases 1 dKH in 100 liters\u003c\/li\u003e\n\u003cli data-start=\"1292\" data-end=\"1370\"\u003eIdeal for reef aquariums that require precise control over alkalinity levels\u003c\/li\u003e\n\u003cli data-start=\"1371\" data-end=\"1446\"\u003eCan be dissolved in freshwater and added to the sump for easy application\u003c\/li\u003e\n\u003cli data-start=\"1447\" data-end=\"1529\"\u003eRecommended for daily or weekly use depending on the aquarium's consumption rate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"1531\" data-end=\"1818\"\u003eReeflowers Pure KH 250ml is an effective solution for increasing carbonate hardness and stabilizing pH levels in reef aquariums.
