The Red Sea Reef Foundation Complete Pack is a hobbyist staple at The Coral Boutique — bundling all three of Red Sea's flagship foundation supplements in one ready-to-dose starter pack. If you're new to dosing, transitioning from water changes to active supplementation, or just want to standardize your reef chemistry on one trusted brand, this is the cleanest place to start.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eCalcium, alkalinity, and magnesium are the three foundation elements corals consume daily to build their skeletons. In a closed reef aquarium, these elements deplete fast — and once you're past a few small frags, water changes alone can't keep up. The Reef Foundation Complete Pack solves that with three precision-formulated, ready-to-use liquid supplements designed to work together: \u003cstrong\u003eFoundation A (Calcium+)\u003c\/strong\u003e delivers a calcium and strontium complex in seawater-correct ratios; \u003cstrong\u003eFoundation B (KH\/Alkalinity)\u003c\/strong\u003e provides a high-purity carbonate and bicarbonate buffer to keep dKH rock-solid; and \u003cstrong\u003eFoundation C (Magnesium)\u003c\/strong\u003e locks in the Mg levels that prevent calcium and alkalinity from precipitating out of solution. Together, they form the backbone of Red Sea's complete Reef Care Program — the same system used by reefers worldwide to grow vibrant, well-colored SPS, LPS, and softies. Each bottle is ready to dose straight from the cap with no mixing, works equally well manually or with a dosing pump, and includes a measuring cup for easy daily use.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePackage Contains\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e1 × Red Sea Reef Foundation A — Calcium+ (250 mL)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e1 × Red Sea Reef Foundation B — KH\/Alkalinity (250 mL)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e1 × Red Sea Reef Foundation C — Magnesium (250 mL)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eMeasuring cup for accurate dosing\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eFull dosing instructions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eAll three core reef parameters covered in one starter pack\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eHigh-purity, ready-to-use liquid formulas — no mixing required\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003ePromotes strong coral skeletal growth and vibrant coloration\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003ePerfect introduction to active dosing for newer reefers\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eCompatible with manual dosing or automatic dosing pumps\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eDesigned to work together without disrupting ionic balance\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003ePart of Red Sea's complete Reef Care Program\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eQuick Stats \u0026amp; Dosing Guide\u003c\/strong\u003e Product Name: Red Sea Reef Foundation Complete Pack (Calcium+, KH\/Alkalinity, Magnesium) Manufacturer: Red Sea Package Size: 3 × 250 mL (3 × 8.5 fl. oz.)
