Calcium is one of the most actively consumed parameters in a reef tank, and keeping it stable is fundamental to healthy coral growth across all species. Foundation A is formulated as part of Red Sea's three-part Reef Foundation system, working alongside Foundation B (alkalinity) and Foundation C (magnesium) for balanced, predictable water chemistry.\u003c\/p\u003e\n\u003ch3\u003eWhy we love it\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHighly concentrated formula that works efficiently in systems of all sizes\u003c\/li\u003e\n\u003cli\u003eRaises calcium without significantly impacting other parameters when dosed correctly\u003c\/li\u003e\n\u003cli\u003ePairs seamlessly with Foundation B and C for a complete, structured dosing routine\u003c\/li\u003e\n\u003cli\u003eCompatible with manual dosing or any standard dosing pump\u003c\/li\u003e\n\u003cli\u003eClean and clear in solution with no unwanted additives\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDosage guide\u003c\/h3\u003e\n\u003cp\u003eDose per 100 L (25 gal) to raise calcium by approximately 8 ppm.
