**CUSTOMER NOTICE** Due to unforeseen circumstances caused by ill health, with much sadness we have decided to close Reef Lounge Aquatics. We would like to thank all our loyal customers, suppliers, family and friends who have been instrumental in growing the business and supporting us through our journey over the past 2 years. This was a very difficult decision for us to make and we would like to invite you all to a closing down sale which will begin this coming weekend. We look forward to seeing you all in the next few weeks. Best wishes The Reef Lounge team.

Reef Advantage Calcium™ is a non-caustic (pH 8.3–8.6) optimized blend of ionic calcium designed to restore and maintain calcium to levels found in natural seawater. 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. Reef Advantage Calcium™ 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. Add 1 capful (5 mL) per 80 L (20 gallons*) twice a week. You can increase the amount or frequency based on growth response but do not exceed 3 capfuls per 80 L (20 gallons*) per day. Each capful will raise calcium by about 3 mg/L. HINTS: Use the Reef Status™: Calcium test kit to measure calcium. It is not necessary to exceed 380 mg/L total calcium when using this product. Color and clarity may vary between lots.
