Seachem Laboratories Reef Calcium Information

Product Manuals & Documentation

Seachem Reef Calcium ™ is a concentrated (50,000 mg/L) bioavailable polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH (formulated at pH 8.2). 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 inhibits calcium precipitation/alkalinity depletion. One side benefit includes enhancement of denitrification. 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 Kalkwasser™). 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. Each 100 mL treats up to 1,600 L (400 gallons).

Comments: I've used this many times in starting newer tanks develop coraline. I don't know the reason, but it has always helped. I use a few of the Seachem products for many years.

Comments: This works great, sugar based polygluconate complexed calcium works wonders for Coralline Algae. There are a few forums and a few threads on reefcentral discussing its success. Keep an eye on your alk, ph and magnesisum as well. My rocks are completely covered with coralline. Only took 3-4 months to cover over 50 lbs. 60g w/ T5HO

Comments: I use REEF PLUS, REEF COMPLETE, REEF CALCIUM, REEF ADVANTAGE CALCIUM and REEF BUILDER, like the folks at GARF recommend. Work well, corals are happy and coralline algae is growing well.
