**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 Calcium is a concentrated (50,000 mg/L) bioavailable polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH. Polygluconate complexation confers several benefits: it increases the bioavailability of the calcium, it provides a rich source of metabolic energy to help maintain peak coral growth, and it prevents calcium precipitation/alkalinity depletion. Polygluconate contains no nitrogen or phosphorous, thus it is biologically impossible for it to lead to algae growth in a properly maintained reef system. Reef Calcium may be used alone to maintain calcium but will provide enhanced levels of coral growth when used in conjunction with an ionic calcium supplement (Reef Complete, Reef Advantage Calcium). Reef Calcium is intended to maintain calcium levels; if calcium becomes seriously depleted one should either perform a water change or use an ionic calcium supplement to restore the depleted level of calcium.
