CaribSea Purple Up 16oz – Coralline Algae Growth Supplement

Encourage rich purple coralline algae growth with CaribSea PurpleUp™ 16oz, a patented reef supplement formulated to enhance reef coloration and mineral balance. PurpleUp™ uses a unique dual-method approach—recognized with a U.S. patent—to deliver essential elements efficiently to both the water column and live rock surfaces.

This advanced formula supplies ionic calcium to immediately raise dissolved calcium levels in aquarium water, while Super Sea Calcium™—a micronized aragonite powder derived from natural seawater—targets live rock directly. As it dissolves in place, it delivers calcium, carbonate, magnesium, and strontium exactly where coralline algae grow. PurpleUp™ also replenishes iodine, a critical 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.
