In the absence of adequate magnesium ions, calcium and carbonate ions bond rapidly, depleting their concentrations in the system and creating the false impression that heavier supplementation is required to re-establish the desired concentrations. No matter how much calcium is added, its natural seawater concentration of 412 ppm will never be sustained until the magnesium concentration begins to approach 1, 290 ppm. Once the balance between calcium and magnesium has been established, subsequent calcium supplementation yields immediate positive results. Keeping magnesium within a range of 1, 290-1, 320 ppm will maintain the desired balance, and provides enough of the element to reef-building organisms for the formation of aragonite (~0. 10% Mg by weight).\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ Provides magnesium which helps regulate the balance between calcium \u0026amp; carbonates in aquarium water\u003c\/li\u003e\n\u003cli\u003e✅ Component of aragonite, which is secreted to form skeletal materials for corals, clams, and their allies\u003c\/li\u003e\n\u003cli\u003e✅ Contains no unwanted organic material such as EDTA, gluconate, or polygluconate\u003c\/li\u003e\n\u003cli\u003e✅ Made in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eShipping \u0026amp; Guarantees\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ FREE standard shipping within the United States (3–6 business days)\u003c\/li\u003e\n\u003cli\u003e✅ 100% money-back guarantee for lost or damaged items\u003c\/li\u003e\n\u003cli\u003e✅ Secure checkout with encrypted payment processing\u003c\/li\u003e\n\u003cli\u003e✅ Shipping via UPS, FedEx, and USPS\u003c\/li\u003e\n\u003cli\u003e✅ Ships to lower 48 states only (no PO Boxes \/ APO \/ FPO)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eReturns\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ 30-day hassle-free returns\u003c\/li\u003e\n\u003cli\u003e✅ Items must be unused and in original packaging\u003c\/li\u003e\n\u003cli\u003e✅ Full refund if item is not delivered\u003c\/li\u003e\n\u003cli\u003e✅ Guaranteed delivery within 6–7 business days\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePayment Methods\u003c\/h3\u003e\n\u003cp\u003e✅ Credit Cards, PayPal, Shop Pay, Apple Pay, Google Pay, Amazon Pay, Meta Pay\u003c\/p\u003e\n\u003ch3\u003eCustomer Support\u003c\/h3\u003e\n\u003cp style=\"text-align:left;\"\u003e✅ Questions?
