If the calcium concentration is too low, growth rates will suffer. If it is too high, alkalinity or buffering capacity will be diminished, leading to possible instability of pH. Sufficient magnesium levels are also necessary to maintain the proper balance. It is therefore recommended that the hobbyist measure and control the levels of calcium, magnesium and alkalinity on a regular basis. Strontium is also required for formation of aragonite. Continuum recommends that you maintain a calcium level of between 410 and 450 mg\/L (ppm), an alkalinity level of 7 to 11 dKH (2.5 to 4 meq\/L), and a magnesium level of 1250 to 1350 mg\/L (ppm). Note: Aquarists keeping SPS corals should consider keeping alkalinity at 7 to no more than 9 dKH (2.5 to 3.21 meq\/L). Do not add calcium and buffering (alkalinity) products at the same time. Doing so will cause unnecessary precipitation and possible cloudiness.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ Maximum strength ionic calcium solution for use in marine saltwater aquariums.\u003c\/li\u003e\n\u003cli\u003e✅ Provides essential element for increased growth rates in corals, coralline algae, crustaceans, and more.\u003c\/li\u003e\n\u003cli\u003e✅ Does not contain acetate, gluconates, or other unnecessary organics; phosphate and silicate free.\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?
