CaribSea Purple Up 4oz – Coralline Algae Growth Supplement

Accelerate vibrant coralline algae growth with CaribSea PurpleUp™ 4oz, a patented reef supplement designed to support healthy, natural reef coloration. PurpleUp™ uses a unique dual-action formula that has earned a U.S. patent, delivering calcium and essential trace elements exactly where coralline algae need them most.

This advanced formula provides ionic calcium to immediately raise dissolved calcium levels in aquarium water, while Super Sea Calcium™—a fine aragonite powder derived from natural seawater—targets live rock surfaces directly. As it dissolves in place, it delivers calcium, carbonate, magnesium, and strontium at the rock surface to promote strong coralline development. PurpleUp™ also replenishes iodine, an essential element for coralline algae tissue health that is quickly depleted in closed reef systems. It is not a fertilizer and will not promote nuisance algae growth.
