Fiji Gold Coral and Live Rock Supplement is 100% natural calcium derived from seawater and coral reef substrate. None of the natural resources utilized in this product are derived from living coral. This product can be used effectively to raise calcium, alkalinity and PH levels in your aquarium.
Fiji Gold Coral and Live Rock Supplement is beneficial to all organisms especially those that excrete calcium from their exoskeleton or utilize calcification as part of their physiological process. This product will also rapidly increase the growth of coralline algae on your live rock.
Fiji Gold Coral and Live Rock Supplement contains calcium, magnesium and all major and minor trace minerals in their natural quantities and molecular structure to benefit invertebrates and fish. Because the minerals are in their natural state absolutely no waste or harmful build up of unused minerals will accumulate in your aquarium.
Fiji Gold comes in a convenient 20 ounce container and will treat 1200 gallons at the recommended dosage of one tablespoon per 30 gallons twice weekly.

I couldn't figure out why my reef is now growing green and brown hair algae...bad, till I read the previous review. My sps corals are still doing awesome, unfortunately so is the nuisance hair algae all over. They must not kill the algae seeds when they grind up the coral at the Fiji Gold factory.
