CaribSea Purple Up 8oz – Coralline Algae Growth Supplement

Promote rich, vibrant coralline algae growth with CaribSea PurpleUp™ 8oz, a patented reef supplement engineered to support healthy reef coloration and mineral balance. PurpleUp™ uses a unique dual-action approach that has earned a U.S. patent, delivering essential elements to both the water column and the live rock surface for maximum effectiveness.

The formula provides 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, an essential element for coralline algae tissue health that becomes rapidly depleted in closed reef systems. This supplement is not a fertilizer and does not promote nuisance algae growth.
