Calcium and carbonates are essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health.\u003cbr\u003e\u003cbr\u003e\u003c\/inline\u003e\u003c\/div\u003e\u003cdiv\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cinline style=\"font-family: Georgia; color: rgb(0, 0, 0); font-size: 16px;\"\u003e\u003cb\u003eReef Advantage Calcium\u003c\/b\u003e also includes magnesium and strontium in amounts proportionate to typical utilization ratios (100:5:0.1, Ca:Mg:Sr). This allows one to maintain these two important elements while maintaining calcium. Unlike limewater (kalkwasser), Reef Advantage Calcium does not have a caustic pH and will not deplete magnesium. Used as directed, it will not deplete alkalinity.\u003c\/inline\u003e\u003c\/div\u003e\u003ch4\u003eDETAILS\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003ePackage Description:\u003c\/strong\u003e 2.2 Lbs.

Dissolve in at least 250 mL (1 cup*) of freshwater. Check calcium every 2 weeks and adjust amount or frequency accordingly. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eADVANCED:\u003c\/b\u003e Check calcium level, then follow addition regimen above until calcium is adjusted to 380–420 mg\/L. Each 5 g\/150 L will raise calcium by about 12 mg\/L. Quantity or frequency can be adjusted, but do not exceed 10 g\/150L per day. Thereafter, use as required to maintain calcium. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eEXPERT: \u003c\/b\u003eAfter determining the calcium consumption rate, set up a continuous drip system. Use the following formula to determine how much to add to your top-off water: m=vc\/400 (m=grams to add to top off water, v=volume of tank in liters, c=amount to raise calcium in mg\/L). For example, if you want to raise calcium by 25 mg\/L in a 200 liter tank, then you would add 200x25\/400=12.5 g into the top-off water. [For reference: 1 gallon*=3.8 liters, 5 g=1 teaspoon*]. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eHINTS:\u003c\/b\u003e If used with Reef Calcium, it is not necessary to exceed 380 mg\/L total calcium.
